Osaka and Fukuoka are in the same time zone. When it's 3:00 PM in Osaka, it's also 3:00 PM in Fukuoka. Both cities use Japan Standard Time (JST, UTC+9) and Japan does not observe daylight saving time.
These two major Japanese cities are connected by the Shinkansen (bullet train), with the journey taking about 2 hours and 15 minutes on the Sanyo Shinkansen line.
Any time works! With no time difference, standard business hours of 9:00 AM - 6:00 PM work perfectly for both cities.
Osaka is Japan's third-largest city and a major economic hub known for its food culture. Fukuoka, located on Kyushu island, is famous for its ramen and serves as Japan's gateway to Asia with close proximity to South Korea and China.
