Traveling in Japan -
Frequently Asked Questions
How do I figure the time in Japan?
Japan is all in a single time zone, which is 15 hours ahead of Denver, in the Summer, during Daylight Savings Time (MDST), and 16 hours ahead during Standard Time (MST). Check to see if your travels will be in DST or not. The Old Farmers Almanac can give you the information for the US.
Japan does not use Daylight Savings Time.
Here is a handy quick reference for time mappings (red times are "next day"):
