Sunpu Castle




Sunpu Castle originally started as a yakata, or fortified palace, for Imakawa Norimasa in the 1400's. However, the exact location of this palace or any other details about it are unknown. An actual castle of the type of castle we think of today was built by Tokugawa Ieyasu in 1585. The main keep of Sunpu Castle was said to have been built three times. The second by Ieyasu in 1605 after he turned over the shogunate to Hidetada and the third was two years later after it burned down in a fire. The third keep also burned to the ground in another fire in 1635 and was never rebuilt. The castle lasted in this state until the Meiji Period when the it was dismantled and the moats were filled in. Sunpu Castle is most well known as the "retirement castle" of Ieyasu after he relinquished the shogunate to Hidetada.

Visit Notes

Most people just view the gate and leave, but the grounds of the castle are quite large and worth your time to walk around. There are are 2 good layers of moats remaining and the stone walls have many owner's marks or inscriptions in them. See how many you can find.

On december 18th 2019 i revisited Sunpujô. The first time was 10 years ago. See my comment below. I needed the 100 meijô stamp and so i could see the Hitsujisaru yagura, rebuilt in 2014. Like suggested by the comment of DiegoDeManila, i went first to the "Shizuoka Prefectural Government Office's Annex Building (just across the street from the park's southern edge) and took a lift up to the free-of-charge public observation deck on the 21st floor". From there you have a very nice view of the whole honmaru. There i encountered an old couple. They asked the usual questions and themselves were castle enthusiasts. Yesterday they went to Hamamatsujô and Kakegawajô. They shared their very nice pictures. I took my time on the deck and when i walked to the tatsumi yagura i saw them back. There another man picked up the conversation and he could say 'bonjour'(good morning in french). He plucked a amai natsu mikan from a tree next to us. All 4 ate of the fruit, which was delicious. Then i went to the Higashi gomon. I bought a 360¥ combination ticket to enter the turrets and the Momijiyama garden. There are several combinations or one could pay just for one entrance. Then i went to the Hitsujisaru yagura. The female attendee was glad to use her english and we had a long chat. I saw two 5min videos. The first one is a condensed version of the life of Tokugawa Ieyasu. The second is about the reconstruction of the tower. This video was very interesting. The floors aren't completely rebuilt, so you can't go upstairs, but so one can see the structure inside the turret. After this turret i walked to the excavations of the Tenshdai. You can walk just next to the excavations and a small temporary building houses explanations about the site. The attendee there gave me a nice map of the castle, which i didn't saw elsewhere on the castle grounds. I went to the Momijiyama garden and took some tea with a sweet at the tea house in the garden. Then i realised it was already 13h30 and since i wanted to visit the Toro iseki, a Yayoi period settlement, i left the castle and went to that site. After my visit at the museum of the Toro iseki and that site, i decided to return to Sunpujô. I went to the outer moat in the north of the castle and the moat north around the honmaru. Other excavations are done on the south east outer moat.

I had a great time and the weather was like summer in my country(22°C). I know it's not the norm in Japan in december, but i appreciated it.

Visited 01 Oct '17. Easy day trip from Tōkyō (under 1.5 hr via shinkansen, another 10-15 min on foot from JR Shizuoka Station). The descriptions I'd seen in advance of my visit tended to emphasise the lack of surviving Edo Period material - which was why my initial low expectations ended up being massively exceeded by the end of the day. Large sections of the Sannomaru moat have survived, although this outermost enceinte is now heavily overbuilt with modern structures; the present-day Sunpu Castle Park encompasses just the former Ninomaru and Honmaru enclosures. The Higashi-gomon and nearby Tatsumi-yagura have been rebuilt using traditional materials and techniques, and this same treatment has been extended to the (relatively) new Hitsujisaru-yagura reconstruction on the opposite edge of the Ninomaru compound. Two sections of the former Honmaru-bori have been unearthed and refilled with water; small portions of the retaining wall that once shored up the Honmaru itself can be seen along the side. There's also an interestingly designed canal (meant for controlling the water level) that links the Honmaru-bori to the larger Ninomaru-bori outside. Just north of this is the beautiful Momijiyama Garden, not really a part of the historic castle complex but nonetheless a delight to walk around in, and the garden's tearoom is a good place to take light refreshment in. West of the garden, I came across the highlight of my visit: a massive archaeological dig focussed on uncovering the long-buried foundations of Sunpu Castle's tenshu (as well as nearby stretches of the Honmaru wall), which haven't seen the light of day since they were torn down and covered over in 1896. (I plan to return to Sunpu a few more times in future Japan holidays just to keep track of progress re: the dig.) Before heading "home" to Tōkyō, I stopped at the Shizuoka Prefectural Government Office's Annex Building (just across the street from the park's southern edge) and took a lift up to the free-of-charge public observation deck on the 21st floor, which offered great views of the entire castle compound - or at least the Ninomaru and Honmaru areas - as well as the city of Shizuoka around it. A 2.5-star site for the most part, but I've given it a full 3 stars thanks to the "big dig".

The link below is to gather donations for excavation only. There is no hard plan for rebuilding in the future, but it is certainly a possibility if there is sufficient information to rebuild it historically accurately. The government is much more strict about rebuilding on national historic sites than they were in the past.

I went to Sunpu again at the end of last December as part of a castle trip to the Shizuoka City and Odawara City area. It has been almost two years since my previous visit to this castle. In that time, they have finished restoring the ishigaki (stone walls) around the Otegomon (Main Gate) Ruin. They have started and almost finished building a reconstructed corner watchtower, the Hitsujisaru Yagura in the Nishinomaru (West Bailey.) It will be completed by end of March 2014. Work is also being done on repairing and shoring up a section of ishigaki on the north side of the Sannomaru (Third Bailey) near the Kusabukagomon (Kusabuka Gate) Ruin. BTW, if you look carefully near some of the gate ruins, there are kokuins (insignias) to be found carved into the stone walls indicating which lord was responsible for the construction of that section of ishigaki.

Parts of two of the original three sets of concentric water moats remain, with the middle water moat surrounding the Ninonmaru (Second Bailey) being completely intact. The city has reconstructed the Higashi Gomon (East Gate) and the Tatsumi Yagura (Tatsumi Turret) from Japanese Cyprus. Inside the Higashi Gomon is a museum which includes some nice models of the castle keep, and a big diorama of how the castle and its town looked like during the Edo Period as well as information about the merchant town that grew up around the castle. There are also three nice drawings of and explanations about Azuchi Castle Keep, Osaka (Toyotomi’s Black) Castle Keep, and Sunpu’s Castle Keep side-by-side, so you can really compare the differences in style and design. Sunpu Castle had a keep, which burnt down in 1635 and was not rebuilt. The keep looked like it had five storeys on the outside with five sets of gable roofs, but internally it actually had seven floors. It was a mainly white castle keep with a green roof on the top storey and a section on one of the lower floors that looks in the drawing similar in design to the Tsukimi (Moon-Viewing) Tower part of Matsumoto Castle. The Tatsumi Yagura contains information about the reconstruction of the East Gate and the Tatsumi Turret. The ruins of the gates into the Ninomaru have survived minus the wooden gates. However, most of the Honmaru (Main Bailey) is now just a park with remnants of the innermost water moat left. Sunpu Castle is certainly a good place to visit to find out some information about the Tokugawa Clan as this was the castle where Ieyasu retired to and ranks second in importance after Edo Castle during the early part of the Edo Period. For this castle fan, it rates no higher than 2 stars because there just aren’t enough ruins left, and the fact that the entire Honmaru is now a park with no remains of the former palace or castle keep.

I visited this site on my way to Kakegawajo. When the sakura are blooming, the park and the moats are very beautiful. I think this site deserves 2 stars because the towers were reconstructed using classical materials. But there are not much buildings to visit.
