Weather in Tokyo in May

What to expect

Daytime

This is walking weather. Shade is useful, not essential the way it is in the hot months. A long outdoor day is a reasonable plan.

Rain

Mixed skies in Tokyo in May. Dry days and wet days share the month. Outdoor plans need a backup, not a cancellation policy.

Pack a shell you will actually carry. The monthly table is the place for totals. This is the feel: usable, interrupted.

Evening

Evenings are cooler. A layer helps after sunset.

What to pack

  • Rain jacket

  • A layer for cooler evenings
