K15Art Project



Kanda River

Free Admission

When we look at the city of Tokyo from a historical perspective, the “local resources of the waterfront since the Edo period” centering on the Kanda River, the Nihonbashi River, and the outer moat have immeasurable value. In the Tenmasen Project, a miniature Tenmasen boat (about 25 cm long), modeled after Japanese traditional wooden boats, will be floated on the Kanda River (between Hijiribashi and Manseibashi), and time trials will be held, following the flow of the river. For every 1,000 yen donated, participants will register one miniature Tenmasen boat, and on the day of the event, they will be able to watch the miniature Tenma boats all flowing together from the river’s upstream via webcast. Part of the donation proceeds will be used toward river clean-up, promotion of river culture. This is an art project that aims to change people’s awareness of the river through the event and donations.

commandN (Artist Initiative)

commandN was started in 1997 by members active in artistic and cultural activities. The group took on the name of the Macintosh shortcut key “command+N”. In 2010, it went on to become a general non-profit organization. Under the concept of an “artist initiative”, numerous projects have been brought to the city center through independent planning and operation by artists themselves. The organization held its 20th anniversary exhibition “Open the New page!” in 2017.
