Ota Ward has the most bathhouses in Tokyo and is the ultimate destination for "Kuroyu"—natural black water hot springs rich in ancient organic minerals. Here, you'll find everything from coffee-colored waters and retro, temple-style bathhouses to beautifully renovated modern spots. Based on the Tokyo Sento Association's list, we've gathered 31 sento in Ota Ward (excluding Hisamatsu Onsen, which is currently closed). Why not wrap up your neighborhood stroll by hopping between these unique, pitch-black hot springs?
