Bizen-ya Seikuro, who ran a coastal shipping wholesale business, founded a sake brewery to help the community burdened by heavy rice taxes. This marks the beginning of Tsuujun Shuzo.

The "Kansei-gura" storehouse was built. It is now the oldest surviving sake storehouse in Kumamoto Prefecture.

During the Satsuma Rebellion (Battle of Tabaruzaka), Saigo Takamori's Satsuma army is said to have gathered in Hamamachi and used the brewery as their headquarters for war councils.

Received the Kumamoto Landscape Award in recognition of the brewery's contribution to good scenery while retaining its appearance since founding.

The 2016 Kumamoto earthquakes damaged more than 10 storehouses including the Kansei-gura, resulting in the loss of about 4,000 liters of sake.

Received the 30th Anniversary Grand Prize of the Kumamoto Landscape Award.

In March, the 200-year-old Kansei-gura reopened after a roughly three-year renovation as a new hospitality-focused sightseeing sake storehouse.
