SENTO-DASHI 2021 Tour with Public Bathmobile


<Open Call Project SOCIAL DIVE>

Made from former “sento” (Japanese public bathhouse) parts, a “dashi” (float) will be pulled around the city’s sento – said to be the heart of Tokyo’s local popular culture – as a procession for the Tokyo Biennale festivities.
“Matsuri” (festivals) are a collaborative activity that dig up buried local resources. This touring of “SENTO-DASHI Public Bathmobile” will attempt at bringing the value of the sento’s everyday operations to the local community through the space of “matsuri”. This project is not limited to our current values, rather, it anticipates more diverse participants making discoveries of more multi-dimensional values in sento.

Based in Bunkyo City, the BKY+SENTO-DASHI committee is composed of core members specializing in architecture and urban design. Through an architectural perspective, “Bunkyo Youth (BKY)” rediscovers the often overlooked charms of local areas and continues to share their value. Their activities as a group of people who love the local culture of sento (Japanese public bathhouses) and festivals has already reached its 9th year. While documenting through surveys and tours the many sento that have become closed, they have also engaged in numerous measures to support sento still in operation. In recent years, they are involved in sharing the appeal of not only sento, but also local ryokan (traditional Japanese inns) and other community values they have not yet turned to.
In 2020, when Tokyo will receive more attention than ever before, the volunteers of the Bunkyo Youth will be at the center with the formation of a “SENTO-DASHI committee”. They started this project with serious thought toward creating this “SENTO-DASHI Public Bathmobile” to be carried throughout Tokyo.
