The Floating Castle of Suwa: Takashima Castle

Date: 1st July 2018

It was early Sunday morning when I headed off to Takashima Castle in Suwa, Nagano Prefecture. The roads were very quiet, not many cars passed by as I walked from Kami-Suwa station to the castle. I did see quite a number of foreign tourists around the train station though, whose destination was probably Lake Suwa, increasing in popularity thanks to the popular anime film Kimi no Na wa (Your Name), in which the lake in Iitomori was modeled after Lake Suwa. I had other plans lined up for my day in Suwa, but Lake Suwa was not part of it. Well, another time.


After passing by the somewhat tree-shaded pathway to Takashima Castle, though feeling anxious of the likelihood of falling bird poop (yes, the streets were full of these), I was delighted to see the donjon (main keep) of the castle, which had a brown exterior, something you do not see often in Japanese castles.


Takashima Castle (高島城) was built in 1592 by Hineno Takayoshi, a daimyo of the Suwa Domain who was under Toyotomi Hideyoshi. The Suwa Clan, who was originally the ruler in the area, was defeated by Takeda Shingen of Kai Province and was only able to rise to power following the defeat of the Takeda clan to the Oda Nobunaga and Tokugawa Ieyasu forces. Suwa Yoritada, a successor of the Suwa Clan was a daimyo of the Soja Domain during Toyotomi Hideyoshi’s time. The Suwa Clan was only able to reclaim their ancestral domain in 1601 with Suwa Yorimizu as the daimyo when Hineno Yoshiaki was transferred to the Mibu Domain and as a reward to Yorimizu who was allied to Ieyasu. The Suwa Clan continued to rule the domain until the start of the Meiji era.


Takashima Castle was dismantled in 1875 following the Meiji Restoration which saw many feudal castles destroyed in order to remove the symbol of the Tokugawa’s powers. Reconstruction of the donjon, yagura and castle gate was completed in 1970.


Also known as the Floating Castle of Suwa, Takashima Castle was built on an island in Lake Suwa, connected to the shore by a narrow piece of land. The waters of the lake reaches the edge of the castle thus made the castle to appear as if it was floating on the waters of the lake, and thus the nickname.



After crossing the bridge, the gate you see is the Kabuki-mon (cross-bar gate), the main entrance to the honmaru.

The honmaru area is now a park, perfect for a stroll while admiring the three-storey donjon from afar. The park is a famous spot among locals during the sakura season which usually blooms around mid-April. The wisteria here is also a sight to behold, blooming in the month of May. Here is a post on Tokyo Bling that shows how pretty the castle park is during the sakura season.

The first and second floor of the donjon exhibits artificats related to Takashima Castle and Suwa Domain, while the third floor features an observation deck to view the surrounding of the castle. It seems you can also see Mt. Fuji on a clear day from here!

The turret (yagura) you see in the corner is the Sumi Yagura, which is also used as a storehouse.

      1. I look forward to reading about your visit to the Suwa Grand Shrines Jennifer. They are very important to the Shugendo group I’ve been spending time with. It wasn’t clear to me how easy it was to visit the Shrine on the west side of the Lake. Possibly there is a bus from the nearest train station?

        1. Are you referring to the Honmiya / Maemiya? My post on the Suwa Grand Shrine will be up around next month, which will include the access details. Let me know which of the 4 shrines you are referring to, I can give you the low-down on the access options here.


      2. Dear Jennifer, I obviously have a lot to learn about the Suwa Shrines and their orientation in relation to the Lake! My sense of direction has never been that strong. 🙂 It would be great to learn more about the history of the Shrines. From what I’ve read all four have onbashira? Is that correct? While I plan to visit both the upper and lower Shrines, the one I am particularly interested in is the Main Shrine. 🙂

        1. Hi Jann. Yes all four have onbashira. The upper shrines (Maemiya and Honmiya) are accessible via buses, Maemiya from Chino Station and Honmiya from Kami-Suwa Station. I could not find the timetable online, but you could get a copy of the timetables at the tourist information centre near the train stations. I took the Karin bus No 6 from Kami-Suwa (after the castle trip) to Honmiya. From Honmiya, Maemiya is within walking distance (25 mins).
