Ruyat-e-Hilal Committee-Japan & Far East Astronomy

How the Islamic Calendar Operates in Japan

The Muslim community in Japan, numbering over 250,000 across vibrant metropolitan centers, observes the Islamic calendar under the leadership of the **Ruyat-e-Hilal Committee-Japan**, coordinated by the Japan Islamic Trust and Tokyo Camii.

At a Glance: The Japan Calendar in 3 Key Points

Ruyat-e-Hilal Committee-Japan Leadership: Formed by representatives of major mosques across Tokyo, Kobe, Osaka, and Nagoya.
Far East Astronomical Position: Because Japan is situated in the far east, the new crescent moon is rarely visible on the evening of conjunction, often resulting in month starts 24 hours after Arabia.
Malaysia Accord Coordination: The committee coordinates with nearest Muslim-majority nations (such as Malaysia) when local cloud cover prevents domestic observation.

The Ruyat-e-Hilal Sighting Session

On the 29th of each lunar month, the committee convenes at the Otsuka Mosque in Tokyo. Sighting teams across Japan from Hokkaido to Kyushu submit observation reports.

Far Eastern Geographic Dynamics

Because the moon travels from east to west, when the new crescent is born, it usually sets in Japan before growing large enough to be seen with the naked eye, leading to rigorous verification.

Day Transition Dynamics

The civil calendar updates at 12:00 AM midnight Japan Standard Time (JST / Asia/Tokyo, UTC+9), while religious observance begins at sunset with the Maghrib prayer.
