May is Excellent for Tokyo.
May is often called 'the perfect month for Tokyo.' Average highs of 24°C and lows of 14°C — neither too hot nor cold. Fresh greenery makes Meiji Jingu's forest paths and Rikugien Garden particularly stunning. The catch: early May's Golden Week (April 29 - May 5) brings massive domestic Japanese travel, spiking hotel prices and crowds. International travelers should aim for mid-to-late May.
May's signature event is Sanja Matsuri — one of Tokyo's three great festivals, held in Asakusa. Dozens of mikoshi (portable shrines) parade through the streets, drawing 1.5 million+ visitors. Stay near Asakusa during the festival to soak in the atmosphere from dawn to night.

Yokohama Open Port Festival (mid-May) is the second annual highlight.

Post-Golden Week (mid-to-late May) is excellent value. Business hotels return to $55-67 / ¥8,000-10,000 and attractions become manageable. UV index spikes — wear sunscreen daily.
