Kapukon Yu (加富根湯?) is a public bath in Higashi Komagata, Japan that has been in business for over 60 years. It is E. Honda's favorite spot, and the old gentleman who mans the counter has known Honda since before his glory days as a sumo wrestler. Honda often faces opponents in Kapukon Yu in order to drum up some business to the place, which has been going through some hard times.
The "Hot Water of Edo" (江戸の湯 Edo no Yu?) is E. Honda's stage, set inside of Kapukon Yu. Honda always takes a bath after practice, and he grew up in a large bath since a young age, loving it. Torn between his love for sumo and hot baths, Honda decides to combine both, making an unusual sumo field in the public bath.
