Best overlap: 2:00 PM to 6:00 PM in Tokyo is 8:00 AM to 12:00 PM in Athens.
Keep meetings inside 2:00 PM to 6:00 PM in Tokyo — that maps to 8:00 AM to 12:00 PM in Athens. With 4 hours of overlap, 2:00 PM in Tokyo (8:00 AM in Athens) is a comfortable, repeatable slot for both sides. These times hold for most of the year, but Athens's daylight saving (which Tokyo doesn't use) shifts them by an hour twice annually.
