Total is all inclusive about $12,500USD/mth
Many rent hotel accomodation at hotels nearby to Haneda at 8000Yen/night rather than spending 70,000Yen/mth on a 20sq mtr apartments.Works for me.I keep a bike and suitcase there for storage as do most.
Enjoyable flying overall.With overtime and selling back 2 days/mth netts $15,000/mth with Business class tckt back home.Easy.............
