If you are staying near the Tokyo station, this is the closest and located in a quiet area, not in a city full of people. As you step inside the reception you will feel that they keep the atmosphere quite traditional not like the modern yoga studios you see nowadays. Mainly experienced Hatha yoga teachers.
They have modern yoga styles such as Strala Yoga-Music&Flow, Beauty Pelvis Yoga, Tensegrity Yoga as well, if you are interested to experience new styles. A great curry place right in front of the studio to enjoy after class.
