Japan doesn't do Daylight Savings Time despite the idea being introduced many times, in part due to the Ministry of Education's concerns about an extra hour of daylight's impact on school performance.
They usually adjust for DST correctly. In this case it seems they meant 23:00 PST instead of PDT. It's still only 22:~~ in PST, though no one actually lives in this timezone at this time of year.
