Do you know of a company called Travelience?
Travelience, which is a company that provides sightseeing guidance service for foreign tourists visiting Japan by a tour guide-interpreter, is providing Tokyo tour for Muslim tourists.

While other existing tourist guidance companies places emphasis on efficiently getting around tourist attractions, Travelience provides tours with emphasis on satisfying intellectual curiosity so that tourists can have fun by having their guides pleasurably transmit many information with “More knowledge, More Fun” as their motto.
Also, the other tours they provide are very appealing. We suggest using their service when travelling to Japan.
