Planning Judgment

  • June 29 Arashiyama is still a good plan, but it should start early and avoid trying to turn the afternoon heat into a checklist. Add Gion / Pontocho / Kamo River only after a rest if the family wants a classic Kyoto evening.
  • June 30 is locked as a full Fushimi Inari summit attempt plus the booked Gion Night Walk. Leave early, protect the summit before heat/crowds, return to CHOAN-RIN for showers/rest, and treat afternoon sightseeing as optional.
  • July 1 Kyoto -> Tokyo now works better as a station-buffer transfer day: checkout from CHOAN-RIN by 11:00 AM, use Kyoto Station for lunch and train buffer, board HIKARI 708 at 1:07 PM, arrive Tokyo at 3:42 PM, then go directly to the Asakusa Airbnb check-in.
  • June 28 transfer plan should stay luggage-protective: Uber/taxi from Dazaifu to Hakata, Shinkansen to Kyoto, then Uber/taxi from Kyoto Station to CHOAN-RIN. Fukuoka rain risk is low by transfer time, but Kyoto is damp/humid enough that luggage-heavy walking is not worthwhile.
  • Kyoto looks usable but humid and unsettled. The June 30 summit attempt should start early, with radar checks before any optional afternoon block because rain/thunder risk rises after lunch.
  • July 2 Tokyo should be run as a rainy flex day from Asakusa. Stay east-side by default with Ueno / Ameyoko / Akihabara, let Justin do Ueno Park if rain allows, and use Harajuku as an optional sister-focused thrift branch only if the rain and group energy justify the cross-town move. Tokyo Tower and Skytree are off the plan.

Dazaifu / Fukuoka

  • 2026-06-26: Rain; JMA notes possible intense rain and thunder through late morning. Evening arrival still needs a wet-transfer mindset.

  • 2026-07-02: JMA Tokyo forecast issued 2026-07-02 05:00 JST: rain until evening, then cloudy; possible thunder and intense rain through the morning. Tokyo precipitation probability is 90% from 6:00 AM, 50% from noon, and 10% from 6:00 PM. Tokyo temperature was about 24 C at 9:00 AM.

Action Notes

  • June 29 same-day Kyoto weather check is complete. Keep Arashiyama early, carry water/sun/rain protection, use cafes/shops as heat breaks, and make a rest at CHOAN-RIN the default before any evening classic-Kyoto add-on.
  • June 28 Fukuoka -> Kyoto transfer weather check is complete. Keep the Uber/taxi plan on both ends because it protects luggage and avoids damp/humid station-to-lodging walking.
  • June 30 Fushimi Inari summit + Gion tour weather check is refreshed. Leave by 6:30 AM, attempt the summit before heat/crowds, return to CHOAN-RIN for showers/rest, and make the afternoon optional because rain/thunder risk rises after lunch.
  • July 1 Kyoto -> Tokyo weather check is refreshed. Use taxi support to Kyoto Station if the checkout-to-station move is wet or hot, and go directly from Tokyo Station to the Asakusa Airbnb rather than adding a luggage-heavy stop.
  • July 2 Tokyo same-day weather check is complete around 10:30 AM JST. Use a rainy-day plan: rain buffer first, then Ueno / Ameyoko / Akihabara east-side loop, with Harajuku thrift as an optional split branch only if conditions improve enough.
  • July 3 Tokyo weather check is refreshed for the family Haneda departure and Justin solo Pokémon route. Carry rain gear; plan for cloudy conditions with a moderate afternoon/evening rain chance.

Gotchas

  • Forecasts are volatile in rainy season. Treat this as a planning snapshot, not a guarantee.
  • JMA area forecasts are regional; use live hourly radar and local routing before outdoor walks, mountain paths, or luggage transfers.
  • Thunder/heavy rain language should override itinerary ambition.
