Tsushima Tourism Promotion Center

Constructed in the latter half of the 1920s for banking purposes, this building served as Nagoya Bank, the Tsushima branch of Tokai Bank, and the head office of Tsushima Credit Union before it became the Tsushima Tourism Promotion Center in 2009.
It retains some traces of its banking days and is a Registered Cultural Property of Japan.
The center offers seasonal events as well as a little rest stop and some local souvenirs for sale.
You can also experience a matcha tea ceremony here (this requires a fee and a reservation).
