Yokohama was a fishing village of around 600 people when it was chosen in 1859 as one of the first ports opened to foreign trade — precisely because it was far enough from Edo to be controllable. It is now Japan's second-largest city by population.
The clock: Yokohama keeps UTC+9. Japan's first railway ran from here to Tokyo in 1872, and with it came the country's first public timetable.
Yokohama lies at 139.6°E. Its time zone, UTC+9, is built around the 135°E meridian. The 4.6° gap between them means the clock runs roughly 19 minutes behind the sun: solar noon arrives at about 11:41 rather than 12:00. The zone holds UTC+9 all year — there is no daylight saving here.
The longest day of 2026 is 22 June, with 14h 33m of daylight. The shortest is 22 December, with 9h 46m. The swing between them is 4h 48m. This is the latitude band where the difference between summer and winter evenings is most obvious.
The earliest sunrise and the latest sunset do not land on the longest day. In Yokohama the sun comes up earliest on 14 June at 04:25, while the latest sunset waits until 30 June at 19:01. The equation of time is what separates them: the Earth's elliptical orbit and axial tilt move solar noon back and forth by several minutes over the year.
The sky stays usably light for a while after the sun goes down. In Yokohama that civil twilight runs about 25 minutes at the equinox, stretching to 30 minutes at the solstice.
Every figure in this section is computed from the city's own latitude, longitude and IANA time zone using NOAA solar algorithms (Spencer, 1971), accurate to about ±2 arcminutes below 65° latitude.
