About the activities ahead of iftar, or fast-breaking dinner, the imam said the meaning of fasting was explained to the Japanese participants. The busiest days are Fridays, Saturdays, and Sundays, he added.
"We hosted approximately 15-16,000 guests, of whom 5-6,000 were Japanese, during our iftars at the Tokyo Mosque," he said.
They also collected aid for the people affected by two earthquakes that struck Türkiye in early February, Cinar said.
The mosque is seen as a central point in the collection of aid, he said, adding the Japanese community generously contributed to the relief aid during Ramadan.
Noting that different segments of society visited the mosque and made donations, Cinar said tourists visiting Tokyo from different countries also donated for earthquake victims.
The Imam said representatives of different faiths such as Buddhism, Christianity, and Shintoism also visited the mosque and provided help to the earthquake victims in Türkiye.
Also, the Japanese architect, who converted to Islam this year at the Tokyo Mosque and took the name Islam, shared his feelings and experiences on his first-ever fasting and the month of Ramadan.
"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.
