Golden Week chaos, then the greenest month
May opens with Golden Week, the country's biggest travel surge — avoid those first five days at all costs. What follows is the reward: shinryoku, the brilliant fresh green that fills Kyoto's gardens, wisteria cascading at Ashikaga, and the last comfortable, rain-free weather before June's tsuyu arrives.
Why May Is Special
Wisteria season — two weeks that sell out
May's signature sight is wisteria (fuji), and Ashikaga Flower Park in Tochigi is the master of it — the great 160-year-old wisteria tunnel peaks for roughly ten days from early May, with night illuminations extending the season. Kameido Tenjin in Tokyo is the free urban alternative. The math is tight: wisteria blooms about May 1-15, the same window Golden Week hits, so plan for mid-May when crowds and prices both ease.
Shinryoku — the greenest month
After May 5, Japan settles into shinryoku, the luminous fresh green that appears the moment the rains and heat arrive. Kyoto's gardens — Shisendo, the Adashino Nenbutsu-ji bamboo path, the moss of Saiho-ji — are at their most vivid, and completely unlike the pink of April. It is the quiet month's best secret: famous temples half-empty, mild 15-24°C weather, and hiking at Mount Takao or Hakone with Fuji still snow-capped.
Photo opportunities
- The wisteria tunnel at Ashikaga, ideally before 9 AM or under its night lights.
- Shinryoku reflections in Kyoto's temple ponds — Shisendo at opening hour.
- Golden-prairie light at Mount Takao at late afternoon, with Fuji on the horizon.
Local tips
- Trains and hotels for May 1-5 genuinely sell out — never travel Golden Week unbooked.
- Aoi Matsuri (May 15) in Kyoto is a Heian-era procession that's free and far less crowded than its fame suggests.
- If fixed to Golden Week, trade Tokyo-Kyoto for Tohoku or Shikoku — 80% fewer international tourists.
What's On in May

- Kyoto's Aoi Matsuri (May 15) — Heian-era costume procession
- Kanda Matsuri & Sanja Matsuri in Tokyo (mid-May) — summer begins early

Where to Base Yourself in May
Tokyo or Kyoto both shine — skip the first week
After May 5 either city is superb. Tokyo's wisteria and fresh-green gardens are walkable from the city; Kyoto's temples glow green and its famous streets empty out once Golden Week tourists leave. For wisteria, base in Tokyo for the Ashikaga day trip.
Best May Day Trips
- Ashikaga Flower Park, Tochigi — the great wisteria tunnel
- Kamakura — hydrangeas still buds, beaches warming, temples in fresh green
- Mount Takao — early-season hiking with a clear Fuji view
Money in May
Prices triple for Golden Week itself, then fall back to shoulder-season levels from May 6. It's the sweetest value of spring if you time it right — weather is still perfect and rates drop 30-50% overnight.
Local Tip
Never book trains or hotels for May 1-5 without reservations — they genuinely sell out. And if your dates are fixed to Golden Week, go to less-touristed areas like Tohoku or Shikoku instead of fighting the Tokyo-Kyoto corridor.
