What Time Is It in Japan? JST and Prayer Hours in Kobe
Japan runs on JST, UTC+9, with no daylight saving. How to convert from home, and how sunrise, solar noon and sunset set prayer times in Kobe.
Japan runs on Japan Standard Time, written JST, which is nine hours ahead of Coordinated Universal Time (UTC+9). The whole country, from Hokkaido to Okinawa, shares this single time zone, and the clocks never move for summer, so the time in Kobe is always UTC plus nine hours: when it is 12:00 UTC, it is 21:00 in Kobe. What changes through the year is the sun, and with it the five daily prayers that a Muslim traveler sets by dawn, solar noon and sunset.
What time zone does Japan use?
Japan uses one time zone, Japan Standard Time, listed in the international time zone database as Asia/Tokyo and fixed at UTC+9 all year. Its reference line is the meridian of 135 degrees east, chosen by Imperial Ordinance No. 51, issued on 13 July 1886, which made the national standard time take effect on 1 January 1888. Before that, each region kept its own local solar time, and Tokyo and Osaka, about five degrees of longitude apart, ran roughly twenty minutes apart.
The 135th meridian runs through Akashi, the city that borders Kobe to the west, and the Akashi Municipal Planetarium stands on the line. For a visitor staying in Kitano-cho, the reference point of the national clock is a short ride west on the JR Kobe Line.
Does Japan change its clocks for summer?
No. Japan does not observe daylight saving time. Clocks were moved forward in summer only between 1948 and 1951, under the postwar occupation, and the practice was abolished in 1952. Later proposals to restore it, including a government review in 2007, were not adopted.
The gap between Japan and your home changes only on the days when your own country changes its clocks. If you live in London, Paris or New York, the difference with Kobe shrinks by one hour during your summer and grows back during your winter. If you live in Saudi Arabia, Turkey, the United Arab Emirates, Pakistan, Bangladesh, Indonesia or Malaysia, none of which moves its clocks, the gap stays the same all year.
How far ahead is Japan from Mecca, Jakarta, London or New York?
Japan's clock is ahead of the Middle East, South Asia, Europe and the Americas. The table gives the local time in a few reference cities at the moment it is 12:00 noon in Kobe.
| City | UTC offset | Local time |
|---|---|---|
| Mecca and Riyadh | UTC+3 | 06:00 |
| Istanbul | UTC+3 | 06:00 |
| Dubai | UTC+4 | 07:00 |
| Karachi | UTC+5 | 08:00 |
| Dhaka | UTC+6 | 09:00 |
| Jakarta | UTC+7 | 10:00 |
| Kuala Lumpur | UTC+8 | 11:00 |
| London | UTC+0 in winter, UTC+1 in summer | 03:00 or 04:00 |
| New York | UTC-5 in winter, UTC-4 in summer | 22:00 or 23:00 the day before |
Read the table the other way for calls home. A call placed at 21:00 in Kobe reaches Mecca at 15:00, Karachi at 17:00 and Jakarta at 19:00, while New York is still in the morning of the same day, at 07:00 or 08:00. The calendar shifts too: when the Friday prayer begins in Kobe around midday, Friday has not yet started in New York.
Why does the sun peak so close to 12:00 in Kobe?
Because Kobe sits almost on the meridian of the national clock. The National Astronomical Observatory of Japan places its Kobe reference point at 135.18 degrees east, less than a fifth of a degree from the 135th meridian, which is worth under a minute of sun time. Solar noon, the moment the sun crosses the meridian and the reference for the start of Dhuhr, therefore stays within about a quarter of an hour of 12:00 all year. The observatory's 2026 tables put it at 11:43 from 1 to 13 November, its earliest, and at 12:13 for most of February, its latest. That half-hour swing comes from the tilt of the Earth's axis and the shape of its orbit, not from the clock. The start of Dhuhr in Kobe follows solar noon, so it moves between about a quarter to twelve and a quarter past twelve over the year.
How do sunrise and sunset change through the year in Kobe?
| Date | Sunrise | Solar noon | Sunset |
|---|---|---|---|
| 1 February | 6:58 | 12:13 | 17:28 |
| 21 June | 4:46 | 12:01 | 19:16 |
| 20 October | 6:09 | 11:44 | 17:19 |
| 1 November | 6:19 | 11:43 | 17:06 |
| 22 December | 7:03 | 11:58 | 16:53 |
Kobe's longest days come in late June, with sunrise around 4:46 and sunset around 19:16, about fourteen and a half hours of daylight. Its shortest come in December, with under ten hours: the sun sets as early as 16:48 between 2 and 9 December, and in early January it does not rise until 7:07. In June, Fajr comes well before the 4:46 sunrise and Isha arrives late after a 19:16 sunset. In December, Maghrib can fall before 17:00, in the middle of an afternoon of sightseeing.
Why do two prayer apps show different times for the same city?
Sunrise, solar noon and sunset are astronomy, and reliable sources agree on them within a minute or so. Fajr and Isha are different: they depend on how dark the sky must be, expressed as the angle of the sun below the horizon, and each calculation convention picks its own angle. The Muslim World League uses 18 degrees for Fajr and 17 for Isha. Umm al-Qura University in Makkah uses 18.5 degrees for Fajr and places Isha 90 minutes after Maghrib, or 120 minutes in Ramadan. The Islamic Society of North America uses 15 degrees for both. Asr also has two rules: an object's shadow equal to its length plus its noon shadow in most schools, or twice its length in the Hanafi school, which places Asr later in the afternoon. A phone set to one method and a mosque timetable built on another can therefore disagree on Fajr, Asr or Isha. In congregation, the timetable of the mosque you attend is the one that counts.
Distance inside Japan adds a second layer. The country shares one clock across a long arc of islands, so the same reading on the clock does not mean the same sun. On 21 June 2026, the observatory's tables give Nemuro, at the eastern tip of Hokkaido, a sunrise at 3:37 and solar noon at 11:19, while Naha, in Okinawa, sees sunrise at 5:37 and solar noon at 12:31. Kobe sits in between, at 4:46 and 12:01. A prayer timetable is therefore local to its city. The one printed for Kobe does not fit Otaru, Sendai or Fukuoka, and the mosques of Tokyo, Osaka, Nagoya and Fukuoka each follow their own sun.
What does Japan's clock mean for Ramadan in Kobe?
Ramadan follows the lunar calendar, which runs 10 to 11 days shorter than the solar year, so the month moves through the seasons. Estimated dates based on the Umm al-Qura calendar place Ramadan 2027 between 8 February and 8 March 2027. The observatory's tables for Kobe give a sunrise at 6:52 and a sunset at 17:35 on 8 February 2027, then 6:20 and 18:01 on 8 March 2027. That is between 10 hours 43 minutes and 11 hours 41 minutes of daylight, with the fast itself starting earlier, at Fajr. A June Ramadan, with fourteen and a half hours of daylight alone, would be far longer. To see how those evenings unfold, from iftar at sunset to tarawih after Isha, read about Ramadan nights at Kobe Mosque.
How should you set your phone and plans when you land?
A phone that sets its time automatically switches to JST once it joins a Japanese network, but a watch, a laptop set to manual time, or a prayer app locked to your home city will not. Before your first prayer in Japan, check three settings: the time zone (Asia/Tokyo), the location used by the prayer app, and its calculation method. Train timetables and shop hours in Japan are commonly written on the 24-hour clock: 19:16 rather than 7:16 PM. If you land at night, the guide to praying around Kansai Airport helps you place the first prayer of your trip between baggage claim and the train to Kobe.
Is the time the same in Tokyo, Kobe and Okinawa?
Yes. All of Japan uses Japan Standard Time, UTC+9, so Tokyo, Kobe, Sapporo and Naha always show the same clock time. Only the sun differs: solar noon in Naha comes more than an hour after solar noon in eastern Hokkaido.
How many hours ahead of Saudi Arabia is Japan?
Six hours. Saudi Arabia keeps UTC+3 all year and Japan keeps UTC+9, so 12:00 in Kobe is 06:00 in Mecca and Riyadh, and the gap does not change with the seasons.
If it is morning in London, is it AM or PM in Japan?
It is afternoon or evening. Japan is nine hours ahead of London in the British winter and eight hours ahead during British Summer Time, so 8:00 in London is 17:00 in Kobe in winter and 16:00 in summer.
Sun times in this guide come from the sunrise and sunset tables of the National Astronomical Observatory of Japan for Kobe, Nemuro and Naha, for 2026 and early 2027. The 1886 ordinance, the 1948 to 1951 summer time and the Akashi meridian follow the encyclopedia entry on the history of Japan Standard Time. Prayer conventions follow the published angles of the Muslim World League, Umm al-Qura University and the Islamic Society of North America. Neither source publishes a prayer timetable for a Kobe mosque; for that, the notice board of the mosque you attend remains the reference.
