Musashikoyama Onsen Shimizuyu: Hot Spring Guide & Prices

In Musashikoyama in Shinagawa, close to a lively shopping street, Shimizuyu is a rare hot spring bathhouse with two distinct source waters. One is a clear amber black water rising from old strata, and the other, called the golden water, is drawn from even deeper layers. Being able to enjoy both at an old-fashioned bathhouse price is exactly why it has long been loved by locals.

Highlights

• Two different natural springs to enjoy in one visit
• A fine-textured, clear amber black water
• A second high-quality golden water welling up from deep layers
• An open-air area that feels surprisingly spacious for the city

Enjoying the Seasons

Although it is a city bathhouse, the open-air bath lets you feel the air of each season. In the sweaty days of summer you can cool off in the shopping street afterward, and in the bone-chilling cold of winter the black water warms you to the core. Its easygoing appeal lies in letting you enjoy the seasonal waters as part of everyday life.

Access and Basic Information

• Location: 3-9-1 Koyama, Shinagawa, Tokyo

• Hours: roughly 12:00 to midnight (from around 8:00 in the morning on Sundays)

• A hot spring bathhouse with two source waters (the black water and the golden water) and an open-air bath, plus a few parking spaces

Practical Travel Notes

• Recommended time: Sundays open in the morning, so early hours are a good bet; on weekdays, just after the midday opening tends to be quieter.
• Time needed: about an hour for a bath alone, or half a day combined with the shopping street.
• Avoiding crowds: it fills with locals from the early evening, so for a relaxed soak try just after opening or around midday.
• Real spots nearby: the Musashikoyama Palm arcade, Rinshi-no-Mori Park, and the Togoshi-Ginza shopping street are all close by.
• Budget sense: the bath is bathhouse-priced and affordable; allow extra for the stone sauna or sauna if you use them.

A Quick Tip

Because you can enjoy two genuine hot springs at bathhouse prices, it fills with locals from the early evening. For a relaxed soak, try just after opening or around midday. Pairing your visit with a stroll through the Musashikoyama shopping street brings out more of the neighborhood charm.
