History of Otsuka Mosque:
The story of the Otsuka Mosque is a great example of a community coming together. Before 1999, the Japan Islamic Trust (JIT) had a prayer space in a rented room in nearby Ikebukuro. When their lease expired, the community knew it was time for a permanent home. With the hard work and generous donations from their members, they bought a four-story building in Otsuka, a spot that was easy for everyone to get to. This new mosque, which opened in 1999, quickly became the main office for the JIT and an important place for Muslims all over Tokyo.
