Spring: beauty with a planning premium
Late March and early April can be remarkable, but bloom dates move and the most sought-after rooms disappear early. Travel for Japan first and blossoms second.
Summer: festivals and long evenings
June is humid and often wet; July and August are hot. The reward is a deep festival calendar and excellent access to mountain regions when planned well.
Autumn: clarity and colour
October and November offer comfortable walking conditions across many regions. Colour timing varies by elevation, which makes rail-based itineraries especially flexible.
Winter: quiet detail
Winter brings clear air, fewer crowds outside holiday periods, and a different food season. It is often the best fit for travellers who value atmosphere over a long landmark list.
