Contrary to what you might think, this wall is not part of a museum. It’s actually a rock climbing wall in a designer gym in Ebisu. Illoiha‘s yoga studio is dimly lit like a Manhattan martini bar, and in addition to this awesome wall, it also has a rock bath facility. (Have you ever gotten a hot stone massage? This is like that but 100x more relaxing.) It’s pretty much $30/hr to do anything here–to sit in the bath, or to climb this wall. I would totally do it if I was rich, just to indulge.
