Sunrise today lands at 05:04 and sunset at 06:23 local time, giving 13h 19m of daylight. Those figures come from the city's own coordinates (35.71, 139.80) rather than a country-wide average, so they match what you would actually see from a window in Sumida-ku.
Sumida-ku runs on Asia/Tokyo, which puts the city UTC +9 from Coordinated Universal Time right now. The clock at the top of this page is not copied from your device: it is anchored to our reference timestamp and re-rendered every second against the IANA time zone database, so it stays right even when a laptop or phone has quietly drifted.
Clocks in Sumida-ku stay put all year. There is no summer-time switch to remember, so UTC +9 is what you will get in January and in July alike — useful if you book recurring calls with people in Japan.
