what date will you be reaching in presume Tokyo?
Sat morning? If so i will be more worried whether flight get cancelled or re-timed then what clothes to bring
Typhoon will hit Tokyo around Friday/Sat and will be pretty strong.
The last typhoon last week some flight got cancelled/retimed
I will be arriving Kansai on Saturday night 9pm plus. Hopefully the typhoon would have already passed Kansai area by then.
I will be flying to Sapporo next tuesday too but I don't think that flight will be affected.
