Time Difference: Berlin and Tokyo
Tokyo is 8 hours ahead of Berlin in winter and 7 hours ahead in summer. 9:00 AM in Berlin is 5:00 PM in Tokyo on CET and 4:00 PM on CEST.
Daylight saving note: Tokyo never changes its clocks. It is 8 hours ahead of Berlin on CET and 7 hours ahead on CEST, which runs from the last Sunday in March to the last Sunday in October.
Why Berlin and Tokyo Rarely Share a Workday
Berlin is UTC+1 in winter and UTC+2 in summer. Tokyo is UTC+9 all year. That's a gap of 8 hours on CET and 7 hours on CEST, with Tokyo ahead.
Only Europe's clocks move, so the shift always happens on the last Sunday in March (the gap narrows) and the last Sunday in October (it widens). 3:00 PM in Berlin is 11:00 PM in Tokyo in winter and 10:00 PM in summer.
The date is the second thing to check. A Berlin afternoon is Tokyo's late evening or night, and anything after 4:00 PM in Berlin on CET is already tomorrow in Tokyo: 5:00 PM in Berlin is 1:00 AM the next day.

Best Meeting Time for Berlin and Tokyo
On CET, a strict 9-to-5 day on each side gives no overlap, because Berlin's 9:00 AM start is Tokyo's 5:00 PM close. On CEST you get one hour: 9:00 to 10:00 AM in Berlin is 4:00 PM to 5:00 PM in Tokyo. In winter, the workable fix is an early Berlin start, with 8:00 to 9:00 AM there at 4:00 PM to 5:00 PM in Tokyo.
Avoiding Berlin-Tokyo Time Mistakes
Tokyo is ahead, so a late evening in Berlin is already the next calendar day in Tokyo. With a 8 hours gap, that starts at 4:00 PM in Berlin: 4:30 PM there is 12:30 AM the next day in Tokyo. When the gap narrows to 7 hours, the date line moves to 5:00 PM.
Tokyo is the fixed side, so a standing slot in Tokyo time moves on Berlin's clock each March and October. 4:00 PM in Tokyo is 8:00 AM in Berlin in winter and 9:00 AM in summer. Put both times in the invite, since the abbreviations alone don't tell Berlin which applies.
A Worked Example: An Early Berlin Call With Tokyo
Say a Berlin manager wants a short call with a Tokyo colleague. A 9:00 AM Berlin start is 5:00 PM in Tokyo on CET and 4:00 PM on CEST. On CET that's exactly the Tokyo close, so there's no room at all, and on CEST there's an hour.
Starting an hour earlier changes it. 8:00 AM in Berlin is 4:00 PM in Tokyo on CET and 3:00 PM on CEST. That's a hard start for Berlin but the Tokyo team has most of an hour to spare.
If Tokyo hosts at 4:00 PM, Berlin joins at 8:00 AM on CET and 9:00 AM on CEST, so a standing Tokyo slot moves by an hour on the Berlin clock each March and October.
