Things to Do in Japan in May

May's mild mornings are good for exploring Tokyo's hidden neighborhood temples by bike. The air is crisp at 8 AM when most shrines open, and you'll catch monks sweeping gravel paths while the scent of cedar incense still hangs in morning dew. These 3-4 hour routes thread through Yanaka's cat-filled alleys and the 47-temple circuit in Setagaya - places most tourists never reach.

May's stable weather means Toyosu Market runs its full tuna auction schedule. The 5 AM start feels manageable when temperatures hover around 12°C (54°F) - warm enough for the 20-minute walk from Shijō-mae Station, cool enough that the ammonia smell from the ice doesn't hit as hard. You'll see the famous tuna tail-touching ritual when buyers check fat quality with flashlights.

May evenings cool to 12°C (54°F) - good for outdoor onsen without the winter shock. The contrast between warm mineral water and cool mountain air creates steam clouds that smell faintly of sulfur. Remote ryokan in Hakone and the Japanese Alps offer last-minute availability post-Golden Week, often with private rotenburo (outdoor baths) overlooking rice terraces.

May's seasonal ingredients - bamboo shoots, firefly squid, and mountain vegetables - appear in traditional kaiseki menus. The classes happen in converted machiya townhouses where tatami floors smell of fresh straw and miso paste ferments in wooden barrels along the walls. You'll learn to slice squid into paper-thin sheets and grill bamboo shoots over charcoal that crackles like dry leaves.

Kamakura's coastal cycling routes shine in May's mild weather. The 25 km (15.5 mile) loop from Hase Station to Enoshima Island passes 12 ancient shrines, where waves crash against black volcanic rocks and the air tastes of salt and pine. Morning rides start cool enough that you'll want a light jacket. But by 10 AM you'll be cycling in t-shirts past surfers at Shichirigahama Beach.
