"I got used to fasting gradually, although I could not succeed in the first week," Islam said.
Islam, who also works part-time at the mosque campus, said the Japanese visiting the mosque meet both Islamic and Turkish cultures.
Additionally, Ramadan was also observed at the Tsushima Hagia Sophia Mosque, which was built in the city of Nagoya, 350 kilometers (217 miles) southwest of Tokyo, with the support of the organization of the Islamic Community of Mili Gorus (IGMG) in Germany.
