Guide
The Masuya Seiemon Residence is a historic building located in the port town of Tomonoura, Fukuyama City, Hiroshima Prefecture. It was once the residence of the Masuya family, who thrived as a 'Kaisen Donya' (shipping wholesaler) during the Edo period, handling trade, lodging, and logistics for various domains. The most significant feature is the 'hidden room' where the legendary figure Sakamoto Ryoma is said to have gone into hiding. While the location of this room remained a mystery for many years, a 1989 investigation revealed a hidden attic space preserved exactly as it was in the past. Today, it is open to the public as a precious historical site where visitors can feel the atmosphere of the era in which Ryoma lived and breathed.
This building is deeply connected to the 'Irohamaru Incident' of 1867 during the late Edo period. At that time, Sakamoto Ryoma was involved in complex negotiations with the Kishu Domain and was using the pseudonym 'Saitani Uetaro' to conceal his identity. Legend has it that Ryoma stayed at this residence for several days while evading danger. This is not merely a legend; the existence of his stay is documented in historical records such as the 'Bingo Tsuzu Osetsu Hikki.' This site preserves the traces of an extremely tense period, occurring just seven months before Ryoma's death in Kyoto, as he worked toward the future of Japan.
The greatest highlight is the 'hidden room' open to the public. Discovered in 1989 when a ceiling board was removed, this space had remained untouched for generations. Although there was once no clear way to access the attic, recent renovations since 2010 allow visitors to observe its structure. Experiencing the architectural details of an Edo-period merchant house and the palpable sense of tension from Ryoma's time is a unique experience. Additionally, the attached 'Zakka Shop MASUYA' offers a variety of items that reflect the lifestyle of the Seto Inland Sea, including products made with local traditional techniques.
It is recommended to visit during daylight hours to best appreciate the architectural details and the structure of the attic through natural light. The surrounding Tomonoura area changes its expression with the seasons, and the harmony between the calm Seto Inland Sea and the historic streets makes it a wonderful place for strolls. Please note that the residence is open on Fridays, Saturdays, Sundays, Mondays, and Public Holidays. Visiting during the quieter hours on these days allows for a more serene and contemplative experience.
Beyond simple sightseeing, this site offers a deep connection to Japanese history. By exploring the hidden room, you can trace the footsteps of Sakamoto Ryoma during the turbulent Bakumatsu period. At the adjacent 'Zakka Shop MASUYA,' you can purchase items related to the traditional industries of the Bingo region, such as keychains made from 'Bingo Igusa' (rush grass). These handcrafted items are a testament to the continuation of local craftsmanship. It is a multi-layered cultural experience where historical architecture meets modern local crafts.
