Yoro Valley Goriyaku no Yu: Day-Use Hot Spring Prices

This is a streamside day-use hot spring in the Yoro Valley of Otaki Town, set on the upper reaches above Awamata Falls. With an outdoor bath and a restaurant, it lets you relax surrounded by the greenery of the Boso hills. It is perfect for a soak after a hike or a stroll among the autumn leaves.

Highlights

The highlight is the outdoor bath where you soak while gazing at the mountain stream. Wrapped in the sound of water and the calls of birds, it makes you forget the bustle of the city. Awamata Falls is about 800 meters upstream, within walking distance, so you can enjoy both a valley walk and the hot spring at once.

Enjoying the Seasons

Yoro Valley is known as one of the prefecture best spots for autumn leaves, usually peaking from late November into early December. The outdoor bath after viewing the colored valley is exceptional. The fresh greenery of spring and the cool streams of summer are appealing as well.

Access and Basic Information

The address is 176 Awamata, Otaki Town, Isumi District, Chiba. It is open from 10:00 to 18:00, with last entry at 17:00. Visiting by car is convenient, and there is parking on site. As it is some distance from Yorokeikoku Station on the Kominato Railway, take a bus or taxi from the station. Closing days and fees may change by season, so check the official site before visiting.

Practical Travel Notes

The autumn leaf season, usually late November to early December, is recommended, but the whole of Yoro Valley gets crowded then, so an early visit is reassuring. Plan on about one to two hours for bathing and a meal, or half a day including the walk to Awamata Falls. Budget around a thousand yen for bathing only, or a few thousand yen if you use the restaurant. Combining it with Awamata Falls, a gently sloping cascade about 30 meters high, the hiking trails of Yoro Valley, and the surrounding hill scenery makes for a day fully enjoying the nature of Boso. As footing near the stream gets wet easily, comfortable walking shoes are a safe choice.

A Quick Tip

Combining it with a journey along the Kominato Railway and Isumi Railway local lines is also recommended. In the autumn leaf season the roads and parking get crowded, so an early visit is reassuring. After working up a sweat on a hike, the streamside bath feels wonderfully good.
