Akan Lake Marimo Exhibition and Observation Center

At the Marimo Exhibition and Observation Center on Churui Island in Akan Lake, you can observe these rare spherical marimo up close through tanks. Exhibits showcasing marimo exceeding 30cm in diameter—among the world's largest—and their growth process are a must-see. The location, accessible by sightseeing boat across the lake, also tickles your sense of adventure. Panel exhibitions are also rich with information about why marimo grows spherical and the fascinating ecology behind it.
