This episode we take a look at the reign of Takewo Hiro Oshikuni Tate, aka Senka Tenno, and we take our first steps into what is referred to as the Asuka Period, due to the large number of rulers who had courts in the region of Asuka in the southern Nara Basin.

Welcome to Sengoku Daimyo’s Chronicles of Japan. My name is Joshua and this is Episode 80: The Asuka Period Begins!
When last we looked at the Chronicles, we were in the reign of Magari no Ohine, aka Ohoye—though we’ve gone with Ohine so I’m going to stick with that—aka Ankan Tennou. Assuming the dating in the Chronicles is correct, he was born about 465, and would have come of age in the era of Wakatakiru no Ohokimi, aka Yuuryaku Tennou. When his father, Wohodo no Ohokimi, first took the throne in 507, Ohine would would have been in his early forties—his father only in his mid to late 50s. And so when his father passed away about 25 years later, Ohine was already into his late 60s, himself. It is unclear whether his father reigned for 25 or 28 years; the Chronicles say 25, officially, but then note that there is another source that claims it was 28. It goes on to skip over about three years, during which Ohine himself didn’t take the throne, allowing for 28 years to have passed. That discrepancy of three years may not seem like much, but it is still curious.
Realistically, though, he had his hand on the tiller of the ship of state for much longer. We see his hand in stories dated to about 513, when he is shown politicking on national issues, taking a royal princess as his wife, and being established as the heir apparent. So he is actively participating in the government, and while it does appear that the long tradition of co-rulership, which we’ve discussed a few times, may have died out around this period, there seems little doubt as to his influence in the court.
And yet, Ohine’s reign only lasted two years. He was perhaps 68 or 69 years old when he took the throne, and he would die in the following year. Despite his influence, his father’s long reign had kept him off the throne for much of that time, and he was likely considered venerable even as he took the throne. He was succeeded by his maternal brother, the second eldest son of Wohodo no Ohokimi, who full name was Take-wo Hiro Kunioshi Tate. Based on his age and the dating in the Chronicles, he was only about one year younger than his older brother. So everything I said above about Ohine coming to the throne at a late age applies to Takewo as well - he would have also been through almost 7 decades by that point, so he was no spring chicken.
It is unclear what Takewo’s role was, growing up. He was the second son. His older brother was the heir apparent, and had his elder brother had children, no doubt those children would have been expected to inherit. However, such as not meant to be, as Magari no Ohine died childless.
Here I should point out that there were other brothers, since in the stories we’ve seen so far there has not necessarily been an insistence on the eldest brother taking the throne. One of these brothers was the young Ame Kunioshi Hiraki Hiro Niwa no Mikoto. Born to Wohodo and his formal queen, Tashiraga, he would have been 26 at the time of Magari no Ohine’s death. Young, in comparison to Takewo, but not impossibly so, and certainly old enough to have taken the throne. In fact the Chronicles treat it as a forgone conclusion, though that is likely more twenty-twenty hindsight than anything else. Besides, although his mother was queen, that appears to have been a blatantly political marriage, designed to join Wohodo’s line with that of the previous sovereigns. Even Ohine had married a royal princess from the previous ruling line, and Takewo would be little different.
Still, it seems likely that Takewo and Ohine were likely from the more favored line, at least at the time, and as they took the throne, had they had heirs who could follow after them those heirs would have likely been the new royal lineage.
So: both Ohine and his brother came to the throne quite late in their lives, and neither would hold it for very long. That doesn’t mean, though, that there aren’t some important tidbits for us in their stories. As we’ve discussed in the last few episodes, a lot happened during Ohine’s reign, particularly with the establishment of various royal granaries. His entry in the Nihon Shoki is over twice the length of Takewo’s, even though the latter’s reign was longer, though not by much—lasting from the twelfth month of 535 to the spring of 539—a little more than three years, all told.
Still, Takewo’s reign has a few notable events. First such thing is the enthronement ceremony in the twelfth month of 535, as the Ministers of the court delivered up to Takewo the regalia—the sword and the mirror. Notice that there is no mention of the jewel, and neither is their mention of the seal, which was the item given to Takewo’s father, Wohodo, on *his* ascension, which we discussed back in Episode 75. This continues something of a trend, where the sword and the mirror are the truly public regalia.
Then, they moved the palace, as was customary. The Chronicles say that they set it up in Ihorino, in Hinokuma. This has traditionally been identified as being in the Hinokuma district of Asuka, near Omiashi jinja. Omiashi jinja claims to be the family shrine of the Aya, one of the families that trace their lineage back to the weavers brought over from the Korean peninsula. That family, much like the current dynasty, traced their own lineage back to the time of Homuda Wake, and I wonder if there wasn’t some kind of connection that would have made Hinokuma important to the sovereign and the court back in the early 6th century.
It is also near the site of the ruins of Hinokuma temple, said to have been established over a century later, in 686. Temples often were their own kind of symbol, and likely spoke to some importance for this area at the time it was founded, though it is likely that was coincidental to the site’s use by Takewo and his court, assuming the Chronicles can be trusted on that point.
Now some of you, like me, may have picked up on the location of this palace; that is to say, Asuka. As in the Asuka period. This is the period, between the 6th and 7th centuries, when many of the sovereigns based their capitals out of this region south of Kashihara in the Nara Basin, and hence the name. We’ll talk more on this periodization—as well as the various dates and what they mean—later on in the episode. For now, just know that this area, which is rich in archaeological evidence for this period, is going to be of particular importance to us—so much so that scholars have named an era after this region.
After setting up the palace, we are told that Takewo appointed his ministers. Two of the names are no surprise—Ohotomo no Kanamura and Mononobe no Arakahi were still around, and had continued in positions of power. Two new names join the list, however: Soga no Iname no Sukune was made Oho-omi, and Abe no Ohomaro no Omi was made Daibu.
Soga no Iname comes from the famous Soga clan. They claimed descent through none other than the famous Katsuragi no Sotsuhiko, and have popped up now and again. For more on Sotsuhiko, check out episode 47. The last mention appears to be during the reign of Wakatakiru no Ohokimi, when they mentioned Soga no Karako—which looks like it may be talking about someone born on the Korean peninsula. Given their connections to the continent and their eventual connection with Buddhism—as we’ll see in later episodes they played a large role in bringing it over and popularizing it in Japan—it seems quite likely that they had ties to the Korean peninsula. Here, we see Soga no Iname being made Ohoomi, the head of the Soga no Omi family, and what appears to be a rank of prime minister, although so far the actual authority of the Oho-omi in State affairs seems a bit hit or miss.
Abe no Ohomaro, on the other hand, is being made Daibu. This term is interesting—they are not making Ohomaro the head of the Abe clan, which would also be Ohoomi, one assumes, just like the Ohomuraji of the Ohotomo and Mononobe, though there are a lot of “Omi” ranked families that have been mentioned, but only a handful who have been mentioned as Oho-omi. The term “daibu” has shown up a few times in the Chronicles before, and generally just seems to refer to high ranking court officials, generally, though here it seems to be a specific court title. It would certainly be used that way, later, but it is also possible that, like Omi, it was originally just a more general term for high ranking ministers.
The Abe family has shown up here and there. Much like the Mononobe, their family name appears to suggest that they were originally formed as one of the “-Be” corporate family groups, though of course they show up in the Chronicles well before that would seem to have been the case, and have been prominent enough to marry daughters off to various sovereigns, so they at least claim something of a pedigree. They would continue to be important at court, and appear to have been close allies with the Soga clan, at least in this period.
There are a host of famous Abe throughout history. From the poet, Abe no Nakamaro, to the famous Onmyoji, or Yin-yang diviner, Abe no Seimei. There was a branch of Abe in the Tohoku region that regularly caused problems for later courts. And of course there is the modern political dynasty, as well, including the late Prime Minister, Abe Shinzo. However, it is somewhat difficult to know just who is actually related. The poet Nakamaro may be named for a village, rather than for his relationship to the court family. There are even different ways of spelling and pronouncing the Abe name, even in the Nihon Shoki itself. The Abe family was large enough that it would not have been difficult for someone to claim a relationship that didn’t exist, particularly in some of the more chaotic times. Still, we’ll try to keep track of them as best we can, at least as they interact with our narrative. In this case, that means keeping an eye on Abe no Ohomaro and his position at court.
Besides affirming the ministers, there was also the appointment of a queen. Here we again see the trend to connect this dynasty with the previous, as Takewo’s primary wife was none other than Tachibana no Nakatsu, a daughter of Ohoke no Ohokimi, aka Ninken Tennou. Together they had one son and three daughters, so technically it would appear that he did have an heir when he passed, but as we’ll see, that isn’t quite how the succession ended up working out.
One of the major events of this reign seems rather substantial. That’s the creation of a government house—basically an administrative center—in northern Kyushu, specifically in Nanotsu no Kuchi. Ostensibly it was to organize granaries to consolidate and distribute food as necessary. Of course, it can’t be forgotten that rice was not just food, but also the basis of the economy. So granaries were just as much a place that taxes could be collected, and that would have given officials there a tidy sum, some of which was no doubt destined for Yamato, but which I imagine was also used to help grease the wheels of local government.
We’ve seen this coming for some time. We see the military subdual of Kyushu in the old stories, and we see various people sent out to bring it to heel or otherwise administer at least the northern areas, which would have been part of the critical trade routes between Yamato and the mainland. Mononobe no Arakahi had been sent down with what we are told was a “battleax” of office to put down the Iwai Rebellion. That was about ten years ago, and we see Arakahi still in the government. Now, however, Yamato seems to be consolidating its hold over the area, instituting economic controls, beyond just the threat of military force.
There are also the various areas and families that they drew upon to fund and kickstart this venture. Most of it is from the Yamato region—Mamuta, in Kawachi; Owari, near modern Nagoya; Nihinomi, likely near Ohosaka; and Iga. The families in charge of this include Aso no Kimi, who must have had some leverage in Mamuta; Soga no Iname, who held influence of the Owari no Muraji; Mononobe no Arakahi, who apparently was in charge of the Nihinomi no Muraji; and then the Abe family, who directed the Iga no Omi. Of these, I find the Aso no Kimi most intriguing, as the others are all related to the great ministers of state. Aso no Kimi feels out of place, to me. It may be a reference to Mt. Aso or similar. But I also can’t help but notice that we have one Great Minister missing: Ohotomo no Kanamura, though not for long.
The rest of the setup of this government house—what sounds suspiciously like the area we’ll later come to know as the Dazaifu—included commandments that the local regions of the island of Kyuushuu also provide funds, which is to say rice. They consolidated reserves from Tsukushi, Hi, and Toyo, which is mostly northern Kyushu.
This was all in the year 536. Whether that is when it was commanded or that is when it was setup is not quite clear to me. One suspects that it would have fallen to Mononobe no Arakahi to administer things from this new government center, if it weren’t for that fact that Arakahi passed away only about a month later.
It is unclear who administered this new government house immediately, but in the year following, 537, and with Silla breathing down Nimna’s neck, Takewo’s government assigned Ohotomo no Kanamura’s sons, Iwa and Sadehiko, to assist Nimna. Iwa took charge of the government in Tsukushi, which would have been supplying any adventures on the peninsula, including raising troops and making preparations. Meanwhile his brother, Sadehiko went to Nimna and, we are told, “restored the peace” there, as well as lending aid to Yamato’s ally, Baekje.
This is rather vague. I don’t see anything in the Samguk Sagi that clearly equates to this. In 532, the Silla Annals talk about the King of Keumgwan Kara surrendering to Silla, though Kara would continue to be a going concern for at least another sixty years or so. It is possible that this had something to do with this new expedition around 537, but it isn’t clear.
Takewo would pass away in 539. His kofun near Mt. Unebi, just a little ways north of his palace at Hinokuma. It is identified as one in modern Toriyacho. It is said that he was buried together with his wife, Tachibana, and one of their children, who died while still quite young.
And that’s where we might end things, but there are a few other points to note for this period. For one thing, this is a great time to discuss periodization in Japanese history, since some people claim that the Asuka period started during this reign—specifically referencing the date of 538.
Periodization of historical eras often seems straightforward, but more often than not it is anything but. Periods may be designated for political reasons or even cultural. Political reasons may include things like a change in government, or even a change in the location of government. Certainly the Nara period, starting in 710, is based quite squarely on the foundation of Heijo-kyo, the continental style capital in modern Nara city. Likewise the Heian and Kamakura eras are often dated from the founding of the governments in those areas.
However, just because the government moved does not necessarily mean that things changed overnight, or even much at all. Likewise there were smaller changes that often happened within these periods, so within the Heian and Kamakura periods, you get terms like the Fujiwara and Insei periods to denote specific aspects of who was controlling the government at any given time.
For some, that means that the Asuka period doesn’t start until the reign of Toyomike Kashikiya-hime, aka Suiko Tenno, in 593, and by the narrowest definition only continues until the Taika reforms in 645, which are easily defined political dates with broad agreement across the scholarship for when they occurred.
And yet, we know that there were governments based out of the Asuka period before that, if the Nihon Shoki is to be at all believed. So if this is about the location of the capital, why not start it with Takewo and his palace? Shouldn’t that be the start of the so-called “Asuka Period”? After all, during this period the sovereigns continued the practice of building new palaces upon their ascension, with most, though not all, being in the Asuka area. And yet, that probably wouldn’t really help break up the period in the most meaningful ways. After all, if we go with that idea, why not start when Wohodo no Ohokimi built his palace in Iware, just a little to the north? What was so different from one to the other?
On the other hand, cultural periods tend to focus on changes in things like art or even thought. These often overlap well, but not exactly, with political periods. For instance, you may hear about the Higashiyama period, a time in the Muromachi when the Higashiyama era of Kyoto was ascendant, and it was influencing artistic growth and evolution across the country. But even that is a hard thing to tack down.
For the Asuka period, perhaps the biggest change – and one we will spend a lot of time discussing – was the introduction of Buddhism, that foreign religion from India, transported across Eurasia to the Korean peninsula and then over to Japan. The primary figure to whom the spread of Buddhism in Japan is attributed is the enigmatic Shotoku Taishi, who served as a regent for Toyomike Kashikiya hime, and instituted myriad reforms, often along continental models. And yet, if we want to look at the start of Buddhism, that actually goes further back—and for many it goes back all the way to the years included in this reign—specifically the year 538.
Now the year 538 in the Nihon Shoki contains no mention of Buddhism. In fact, the Nihon Shoki wouldn’t have a record of anything related to Buddhist teachings coming to Japan until about 13 or 14 years later, in the reign of the following sovereign, known as Kimmei Tenno, whom we will be getting to shortly. This chronicle states that it was in about 552 when an envoy from Baekje brough an image of the Buddha as well as Buddhist scriptures to the court.
However, these days it seems that many scholars prefer a date of 538 for this particular event. The 538 date comes from the records of Gangoji Temple—the Gangouji Garan Engi—as well as the Jouguu Shoutoku Houou Teisetsu, aka the Jouguu-ki. This latter is purported to be a biography of Shotoku Taishi, and comes from the 8th century, so contemporary with the Nihon Shoki, the Kojiki, and the Sendai Kuji Hongi. Both of these sources lend credence to the idea of 538 being when these Buddhist icons first came over, and so many people will start the Asuka period at this date.
To be clear, it isn’t as if Buddhism came over once and that was the end of it and everybody became Buddhist. This is just the first recorded instance of Buddhist items and ideas entering Japan—it wasn’t until later, as the court was adopting more and more continental ways, that Buddhism really gained acceptance and spread. Eventually it seems that state sponsorship of temples would override the construction of large kofun, as economic resources and labor were shifted to these new institutions of the state, bringing the Kofun era to its eventual end. But that is still down the road for us. Right now we are just at the beginning of the introduction of Buddhism, and while things are changing and the state is definitely growing, life didn’t suddenly take a turn one way or the other.
As for the date of 538—why was this, in hindsight, incredibly important religious and cultural event not mentioned in the reign of Takewo? Why was it instead mentioned in the reign of his successor? I’ve seen a few theories, but nothing that can concretely answer this question. Of course, there is the possibility that Takewo just wasn’t as impressive. The Chronicles seem to take issue with both his lineage and his elder brother’s, suggesting they weren’t true heirs because they did not have the full pedigree that someone like their brother, Ame Kunioshi, had. Of course, that could also have something to do with the path history took—to the Chroniclers it only made sense, but I think we can all see how that could have turned out differently.
There is also a theory that Ame Kunioshi, aka Kimmei Tenno, was actually co-ruling. Some have even suggested that Takewo and his brother, Magari no Ohine, were fictional, though why they would need to pad things out is anybody’s guess. It certainly does not seem unreasonable to think that some tradition of co-rulership had briefly continued in some form. As such, it may be that it did happen during Ame Kunioshi’s reign, but that said reign overlapped with his brother. If that were the case, the Chroniclers may have been teasing the two apart to provide a more direct narrative.
In the end, it is hard to know exactly why the dates don’t correspond between the different documents, but for our part I think we can say that we have now at least dipped our toes into the Asuka Period, especially as we get into the reign of Takewo’s younger step-brother, the youngest son of Wohodo no Ohokimi, or so we are told: Ame Kunioshi Hiraki Hiro Niwa, aka Kimmei Tennou
But that will be for another episode, and there is so much to talk about: More contact with the continent, further discussion of the coming of Buddhism, and perhaps a look at some of the archaeology, including some volcanic events that don’t seem to have made it into the Chronicles themselves. All of that, coming up.
