About the time in Ōta-ku
Ōta-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.
If you are coordinating from another country, the shortcut is the working window: a normal Ōta-ku day of 09:00–17:00 falls between 00:00–08:00 UTC. Convert your own hours into UTC once and you can tell at a glance whether someone there is likely to be at their desk.
Clocks in Ōta-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.
