May is an excellent time for visiting Tokyo! During Golden Week (late April to early May), the city buzzes with energy, though expect crowds at major attractions. The weather is pleasant, with low humidity, great for exploring parks and gardens bursting with spring foliage.

In May, Tokyo enjoys pleasant spring weather, with average temperatures around 19.5°C (67°F), highs reaching about 24.3°C (76°F), and lows dipping to roughly 15.3°C (60°F). This comfortable climate is ideal for wearing denim, short-sleeve shirts, or light layers. Bringing a light jacket is a smart move for cooler evenings.

(Note: This is based on average weather data for Tokyo from 2019–2024.)

For Children's Day on May 5, Tokyo Tower in Shiba Park will display 333 vibrant koinobori streamers at its main entrance—one for every meter of the tower’s height.

Look closely to spot three quirky eel-themed streamers—two inspired by the spotted garden eel and one debuting in the likeness of a white-spotted garden eel, a nod to Sumida Aquarium.

At the special venue on East Yard 5F, kids and adults alike can join hands-on workshops like hand-painting paper koinobori with guidance from a Kazo craftsman, drawing mini koinobori postcards, and coloring candy-crafted fish from Asakusa’s Amezaiku Ameshin.
