Global rating :    
There is only one ryokan in Hoshi Onsen. Chojukan, which was build in 1875, is considered by some people to be one of the most beautiful ryokan in Japan. Its indoor bath is extremely famous.

Size :    
One indoor bath is available there. At least this bath is quite large.

Modesty :   
This mixed bath might afraid lots of women... After exiting the separate changing rooms, visitors will directly reach the bathing area; it seems that the custom of men in this bath is to fix the women entrance, which can be quite of a shock... Apart of that, due to the darkness of the room, a little of privacy is somehow kept.

Area :    
Located close to Minakami, on the road leading to Echigo Yusawa in Niigata-ken, this area is famous for its ski fields and, of course, onsen. If you visit the area in winter, you might as well continue north to Niigata-ken and the Naeba resorts, where incredible ski will be waiting for you. The rest of the year, this area of Gunma-ken offers many opportunities if you don't want to spend your day in the onsen.
