Totsuka Onsen is a welcoming hot spring in Totsuka Ward of Yokohama, a major suburban district serving as an important rail junction linking central Yokohama with the Shonan coast and the Miura Peninsula. The bicarbonate thermal waters offer gentle skin-softening and relaxation benefits, providing accessible thermal wellness for the large residential population of Totsuka and the surrounding Yokohama suburban districts. The ward's historic role as the Totsuka-juku post station on the ancient Tokaido road — the great highway connecting Edo (Tokyo) to Kyoto — gives the area a deep historical grounding beneath its modern suburban appearance.
