All of Japan, from Hokkaido to Okinawa, uses JST. Japan has not used summer time since the early 1950s, so offsets to Tokyo only move when the other country changes its clocks.
Tokyo sits at the eastern edge of its time zone, which gives it very early mornings in summer. Around the June solstice the sun rises at about 4:25, and in December it sets as early as 16:30. Visitors from Europe often notice how dark the city is by late afternoon in winter.
Tokyo is 3h30 ahead of India all year. A 13:00 meeting in Tokyo is 9:30 in Delhi, which is why many Indo-Japanese teams meet just after lunch in Japan. London is 8 hours behind during BST and 9 hours behind in winter, so London's early morning matches Tokyo's late afternoon.
For the US West Coast, the Tokyo morning lines up with the previous afternoon in Los Angeles. Japanese business culture values punctuality, so check the date carefully when you are working across the Pacific.
No. Japan has stayed on UTC+9 all year since the 1950s.
Yes. Seoul also uses UTC+9 with no daylight saving, so the two cities always match.
Tokyo is 3 hours 30 minutes ahead of India throughout the year.
