History

Matsudaira Norikata founded the castle in 1864. Unfortunately, it was never totally finished by the time the Meiji Restoration began and it was abandoned in 1871. Rather than a huge fort like that of Goryokaku, Tatsuoka Castle is comparatively smaller and it's thought that it was intended as a residence rather than a large scale castle. Also, despite taking in the elements of a European star shaped fortress the moats are fairly narrow and shallow so it would not have been a very strong fortress. Norikata was well respected and served the shogunate in several high ranking positions. After the Meiji Restoration he helped found Hakuaisha, which would later become the Japan Red Cross.


Visit Notes

This is one of only two 5 point sar shaped forts in Japan. Be sure to view the Google map where you can very easily see the star shape that you can't get from this pictures. The castle is about the same distance from either Usuda or Tatsuokajo Stations. I walked from Usuda to the castle and then out to Tatsuokajo. The castle grounds are now occupied by an elementary school, but apparently they are open for walking around. Be sure you don't miss the original gate and wall about a 10 min walk from the castle. the town also has some old temples that are worth a visit if you're there.
五稜郭と一緒に日本に二つしかない稜堡式のお城です。この写真ではその形はよく見えませんが、グーグルマップではよく見えます。お城は臼田駅と龍岡城駅からほぼ同じ距離です。私は臼田駅から降りて、お城を回って龍岡城駅から載って帰りました。城跡は現在小学校がありますが、グラウンドに入ってもいいようになっているようです。城跡から徒歩10分位にある移築現存の薬慰問と塀も見る価値があります。時間があれば古い神社もいくつかあるのでゆっくりついでに散歩して回るのも楽しいです。

Tatusokajō (Saku, Nagano)  龍岡城 [長野県佐久市]

Tatsuokajō is famous as one of two pentagonal star forts in Japan, although there are other "star forts", properly called bastion forts, in Hokkaidō, other than the famous Goryōkaku. Tatsuokajō was the only bastion fort built outside of Hokkaidō in Japan. In fact traditional castles were still being built (such as Sonobejō) when Tatsuokajō was built. Tatsuokajō is best understood as an experimental fort, as it was not built on a large enough scale to be effective as a functional bastion fort. These latter day innovations by the Tokugawa Shogunate make for some strange stories. At least one Tokugawa domain had plans for a submarine! Can you imagine samurai in a submarine? Another part of this arcanery concerns samurai riding camels to Egyptian pyramids! That actually happened. To be sure they were strange times, and Tatsuokajō is a strange castle. Furthermore, even as it was built, Anglo-European powers had already moved on from the bastion fort model and were constructing polygonal forts (for context the Statue of Liberty was built less than two decades later on a bastion fort in New York Bay which had long been obsolete).

Tatsuokajō is bounded on all sides by ishigaki (stone-piled ramparts) and around most of the central star-shaped bailey by a narrow mizubori (water moat). The ishigaki is special, its like being found otherwise only at goryōkaku, because a lip of projecting oblong stones creates an impediment to any attacker that would try to scale the ramparts. The stones are otherwise hewn and slotted together very precisely (kirikomi-hagi). Earth is piled up above the ishigaki into embankments which are set back a little (the stone and earth combination being known as koshimaki-ishigaki when the ishigaki is lower). There are three entrances into the compound, set in the northwest, northeast and east. The south is bounded by the Ama River and the west slopes off into farmland - here the moat ends and becomes a rivulet. An original structure from the castle also survives, o'daidokoro; it is a large kitchen building. It was retained after the castle's closure to function as a school house. It was then later moved away from the castle but has since been re-relocated, though not in the exact same place. The castle's inner compound is now a primary shool, and in one spoke a shrine is located.

The castle also possessed some outer defences, and a masugata (gate complex) ruin remains a little distance from the main site. A relocated gate from the castle apparently stands in the vicinity, now used as the gate of someone's residence. These pictures are ordered larger as taken, apart from some highlights at the front of the set. I've also included a picture of the route I took. Technically I visited two more sites after Tatsuokajō: Tanokuchi-jin'ya, of which nothing remains, and the Yoda-yakata, which is now the temple Banshōin. It was from this latter site that I had intended to climb to Taguchijō, a yamajiro, where there is a viewing area for appreciating Tatsuokajō from above. However, the trail was closed because landslides wiped it out back in March. Hopefully I can go back when I have more time and find a different way up the mountain.

History:

The Ôgyū-Matsudaira, a branch family of the ruling Tokugawa, were originally based at Okutono-jin'ya in Mikawa, but Matsudaira Norikata relocated his main base to Tanokuchi-jin'ya in Saku (the clan's holdings in Saku were three times larger than those of Mikawa). From here he began constructing a new, modernised castle between 1864-1867. Completed (or, stopped being worked on) in 1867, Tatsuokajō was an experimental fort which served as the headquarters of the Ôgyū-Matsudaira Clan. The castle was decommissioned in 1871.

This is one of what I thought were only two western-style star forts in Japan until two more near Hakodate were recently posted on this site. These new two are small and not really stars but rather diamonds or rectangles. Tatsuoka is not as grand as Goryokaku in Hakodate, but it is a genuine star fort. It's occupied by an elementary school, although they don't seem to mind people walking around with cameras. As is often the case, I also pulled up my motorcycle on the grounds and parked. As long as you're not causing problems or arriving in large numbers, I don't think anybody will mind. Having said all that, Tatsuoka is historically interesting, but go to Goryokaku in Hakodate if you want to see a much better preserved star fort and feel free to explore it.
