Ryoma History Museum, Biographical history museum in Kōnan, Japan.

The Ryoma History Museum tells the story of an important historical figure through documents, personal belongings, and displays arranged across several exhibition spaces. The collection helps visitors understand this person's life and its context in detail.

The museum was founded in 1988 and focuses on a person who played a key role in transforming Japan from a feudal system to a modern society during the 1860s. This shift was one of Japan's most important turning points.

The museum's name comes from Sakamoto Ryoma, the Tosa-born samurai whose 33-year life is told in 27 scenes with over 120 wax figures. Konan, where it stands, was home to Tosa loyalists such as Yataro Oishi and Kaientai member Umanosuke Shingu. A scroll certificate of the Hokushin Itto-ryu naginata school is on permanent display.

The museum is in the Actland complex at 928-1 Oya, Noichi-cho, Konan, next to the Shikoku Automobile Museum. It opens daily from 10:00 to 18:00 with no closing days, and parking for 285 cars is free. Entry to the grounds costs nothing; the eight paid exhibition halls charge adults 1000–1500 yen and schoolchildren 500–800 yen, with under-sixes free. It is about 10 minutes on foot from Noichi Station on the Tosa Kuroshio Gomen-Nahari line and 10 minutes by car from Kochi Airport.

The museum preserves handwritten letters and a sword connected to a major event in this person's life. These direct objects allow visitors to feel a personal connection to the past.
