Kyukamura Tateyama Onsen: Hot Spring Guide & Access

Located in the Minami-Boso Quasi-National Park, this is a public resort hot spring that looks out over Tateyama Bay and Mount Fuji. Just a short walk from the beach, it is popular for its all-ocean-view rooms and cuisine made with the bounty of the sea. The large bath Hanaumi no Yu, which views Tateyama Bay, welcomes its visitors.

Highlights

The highlight is the large bath that commands Tateyama Bay. From the outdoor bath you can see the Miura Peninsula and, when conditions are right, Mount Fuji. The spring water is a sodium chloride and bicarbonate cold mineral spring. With stargazing at night and beachcombing in the morning, the activities that bring you into contact with nature are rich as well.

Enjoying the Seasons

In summer, enjoy playing at the nearby beach along with the hot spring. In winter the air is clear, and the chances of seeing Mount Fuji from the outdoor bath increase. Mild Tateyama is also known for flowers and suits an early spring trip.

Access and Basic Information

The address is 725 Kenbutsu, Tateyama City, Chiba. It is reachable by car from the Tomiura interchange of the Futtsu-Tateyama expressway. It is a public lodging facility centered on overnight stays, and day-use bathing is currently suspended. The official Kyukamura Tateyama Day Spa page states that day-use hot spring bathing is not being offered, so only overnight guests can use the baths. Guests bathe from 15:00 to 24:00 and from 5:00 to 9:30, with the baths closed for cleaning at other times. Service could resume, so check the official site or call before visiting.

Practical Travel Notes

Day-use bathing is suspended at present, so plan an overnight stay if you want to use the hot spring, and check the official site in advance in case day use resumes. Plan on about one to two hours for bathing and a rest. In the evening the sun setting into Tateyama Bay is beautiful, and the view from the outdoor bath is exceptional. Nearby are the scenic drive along Hirasago Beach, Tateyama Castle in Shiroyama Park, and the flower fields of southern Boso, which combine well with sightseeing that makes the most of the mild climate. Because day-use bathing is suspended, the hot spring can be enjoyed only with an overnight stay, so budget for a stay rather than for a bath-only visit.

A Quick Tip

Dusk is a beautiful time for the sunset. After watching the sun sink into Tateyama Bay, look up at the night sky and try searching for the stars. Day-use bathing availability changes easily, so do not forget to confirm before you arrive.
