Where to Go in Japan in May

Hokkaido

Sapporo, Niseko, Furano, Asahikawa

May feels like early summer: cool, often breezy, and green everywhere, with Furano’s valleys preparing for the lavender season. Tourist crowds are light compared with Honshu’s Golden Week hotspots, though late-May can be busier around national parks. Mosquitoes are rare early in the month, but hikers should still have waterproofs-the occasional frontal rain passes quickly.

Tohoku & the Sea-of-Japan Coast

Aomori, Akita, Sendai, Niigata, Kanazawa

May opens up bright, grassy landscapes and easier access to rural hot springs and coastal drives; the national parks turn green and waterfalls swell from snowmelt. This is prime time for hiking in higher valleys and for seeing early festivals with fewer international tourists than in Kyoto. Pack a light rain jacket for unpredictable spring showers and cooler evenings.

Tokyo & the Kanto Plain

Tokyo, Yokohama, Kamakura, Mt. Fuji approaches

May’s long Golden Week (late April-early May) brings a domestic travel surge that affects Tokyo’s trains and hotels. Outside the holiday week, days are warm and pleasantly humid-great for strolling through Asakusa or taking a day trip to Kamakura. Expect some crowds at attractions and plan reservations for popular restaurants and museums.

Central Alps & Japanese Alps

Nagano, Matsumoto, Takayama, Kamikochi, Mt. Fuji approaches

May opens lower-elevation hiking and alpine valley exploration as snowline retreats; the high mountain passes typically clear later in the month. Mountain meadows bloom, but high trails can still hold snowfields; crampons and an experienced guide are useful for early-season trekking. Roads are less crowded than Golden Week on Honshu but book lodging if you arrive during that holiday.

Kansai & the Seto Inland Sea

Kyoto, Osaka, Nara, Hiroshima, Okayama, Takamatsu

May contains Golden Week (late April-early May), which creates a massive domestic travel surge-expect packed trains, sold-out hotels and busy attractions. Outside the holiday cluster, late May is warm and sunny, great for ferry trips across the Seto Inland Sea and cycling on Naoshima and Shimanami Kaido. Light clothing and a hat suffice during the day; evenings can be cooler.

Kyushu & Okinawa

Fukuoka, Nagasaki, Kumamoto, Kagoshima, Yakushima, Okinawa main and outlying islands

May brings humidity creeping northward and fans out on Kyushu as the main islands approach the rainy season; gardens are lush from spring storms. Okinawa often begins its early rainy season in May, producing brief heavy showers and high humidity; still, many days are fine for snorkeling. Plan indoor alternatives and flexible ferries for island hopping.

Events & Festivals in May
