A city on the JST meridian
Japan Standard Time is defined by the 135th meridian east, which runs through Akashi, about 50 kilometers west of central Osaka. Osaka itself sits at 135.5° east, so of Japan's big cities it is the one whose clock best matches the sun: solar noon falls between about 11:45 AM and 12:15 PM through the year, depending only on the season. Tokyo, nearly 5 degrees farther east, sees sunrise and sunset about 17 minutes earlier on the same clock.
With no daylight saving, summer mornings start early. Around the June solstice the sun rises near 4:45 AM and sets around 7:14 PM, about 14 hours 29 minutes of daylight. In late December sunrise is close to 7:01 AM and sunset about 4:51 PM, a day of roughly 9 hours 50 minutes.

Osaka's markets and working hours
Offices generally work 9:00 to 18:00, and department stores in Umeda and Namba open around 10:00 and close at 20:00 or later. Osaka has a long trading history: the Dojima Rice Exchange, founded in 1730, is often cited as one of the first organized futures markets. Its successor, Osaka Exchange, part of Japan Exchange Group, is Japan's main derivatives market, with a day session for Nikkei 225 futures and a night session that runs into the early hours of the next morning, so traders can react to US markets.
Osaka against New York and London
Osaka is thirteen hours ahead of New York from March to November and fourteen hours ahead in the US winter: 9:00 AM in Osaka is 7:00 or 8:00 PM the previous evening in New York. London is eight hours behind during British Summer Time and nine in winter. Since Osaka and Tokyo share a clock, the JST to EST page applies to both.
