In 1913, our restaurant was operated in the style of a health spa, which was rare at that time. Since then, it has been rebuilt twice and currently operates on the first floor of a four-story reinforced concrete apartment building.
  We did not apply for a hot spring license as "Take-no-yu," a public bathhouse in the local Azabu Takeya-cho area, but in December 2002, we obtained a hot spring license in order to let more people know about the quality of our hot spring. The name of the hot spring is "Azabu Kokubisui Onsen. The name was based on the color of the blackish-brown water and the comments from customers that their skin feels smooth after bathing in this hot spring water. I have been bathing in this hot spring since I was born, and I think it feels better than any other hot spring I have bathed in! Please take a bath.
