Chichibu Yumoto Buko Onsen is recruiting carp streamers that are no longer used at home. Why not let the carp streamers sleeping at your home play an active role at the "Yokoze Carp Streamer Festival"?

Chichibu Yumoto Buko Onsen (Yokoze Town, Saitama Prefecture, hereinafter referred to as Buko Onsen), operated by Onsen Dojo Co., Ltd. (Tokigawa Town, Hiki-gun, Saitama Prefecture, Representative Director Toshiki Yamazaki), will implement the "Koi Koi Campaign" starting April 11, 2026, to collect carp streamers that are no longer needed at home.

Bring carp streamers that are no longer used at home to the facility and exchange them for a free admission ticket to the facility. The collected carp streamers will be displayed at the "Yokoze Carp Streamer Festival" which will be held from Saturday, April 11.

The "Yokoze Carp Streamer Festival" is a popular annual event in Yokoze Town, where approximately 180 carp streamers adorn the sky above the Yokoze River, which flows right next to Buko Onsen. Carp streamers often sit unused at home after children have grown up. We hope that the children of today's era will grow up healthy and strong, and we wish to see these carp streamers swim once again in the vast sky of Chichibu.

Onsen Dojo, whose corporate philosophy is "transmitting culture from baths," will grandly enjoy and enliven the "Yokoze Carp Streamer Festival" event with the local community.
