The Brimmer Japan trip made it to Osaka, Japan after meeting at Logan at 3 a.m. Monday. The first leg took us to San Francisco and a very brief layover. Trip so far: 6 hours. Then an orderly transition to our international flight, leaving SFO at 11:45 and arriving in Osaka at 4:45 the next day local time. With the 14-hour time difference, that makes a grand total of 18 hours in the air.
