Ramadan 2027 in Osaka, Japan

Sehri and Iftar in Osaka

For Osaka, the evening fast opens at local sunset, shown as 5:11 pm today. The pre-dawn cutoff is calculated separately from the Fajr setting; sunrise is not used as the start of the fast. The page uses Osaka’s coordinates (34.69, 135.50) and the Asia/Tokyo time zone.

Sunrise-to-sunset daylight in Osaka lasts 11 hours today. Across the June and December solstices that daylight span differs by about 4 hours 39 minutes at this latitude. That helps explain why Ramadan feels very different when the lunar month returns in another season, but it should not be read as the fasting duration because Fajr occurs before sunrise.

For comparison, sunset in Sapporo is 4:36 pm today, 35 minutes earlier than in Osaka. Travellers should therefore switch to the timetable for the place where they are actually observing the fast rather than carrying one city’s times across Japan.

This timetable uses the Karachi prayer calculation setting. The calculation notes explain how the site handles Fajr, Isha and unusual daylight conditions, so that general methodology is not repeated on every location page.
