Seasons in Japan
Storm season runs August to October
Japan is in its storm season right now, August to October. Most trips are unaffected, but a storm reroutes flights and closes beaches at a day's notice — the packing consequence is a buffer day and a charged power bank, not different clothes.
Going in October
Typhoon season, with September the most active month. A direct hit stops the trains and grounds flights for a day at a time.
What this means for your bag
A buffer day, and your documents on your phone
Storms reroute and cancel flights at short notice. Leave a day between the trip and anything unmissable, and keep bookings and insurance available offline.
See the Travel Documents Pack packA packable rain shell
Not a winter coat — it stays warm through the rain. A light hooded shell that folds into its own pocket ends up in the day bag instead of the hotel room.
See the Weather Protection packA charged power bank
Power cuts follow storms. A charged bank keeps maps, bookings and your ability to call someone alive through one.
