Yokohama vs Shanghai Time Difference

A 10:00 standup in Shanghai happens at 11:00 in Yokohama. That single hour is the only mental arithmetic you ever need. Neither city shifts clocks for summer, so the gap stays locked at one hour through 2026 and 2027.

Yokohama (JST, UTC+9) = Shanghai (CST, UTC+8) + 1 hour.

If it is 10:00 in Shanghai, it is 11:00 in Yokohama. If it is 15:00 in Yokohama, it is 14:00 in Shanghai. No spring forward, no fall back. China abandoned daylight saving in 1991 and Japan has not observed it since 1951, so the offset never changes.

What Is the Time Difference Between Yokohama and Shanghai?

Yokohama runs one hour ahead, every day of the year. Both cities sit on fixed offsets: Yokohama at UTC+9, Shanghai at UTC+8. The 135°E meridian that sets Japan Standard Time passes near Akashi, well west of Yokohama, so solar noon in Yokohama arrives around 11:42 JST. Shanghai, despite lying slightly east of the standard 120°E meridian for China Standard Time, uses a single national zone that covers the entire country. The practical result is a one-hour gap that never widens or narrows.
