The heat of summer in Tokyo can be overwhelming but the trade-off is that there is a plethora of activities to do during this season. Hanabi or fireworks festivals are a key highlight to summer. You can participate like a local by wearing a yukata (summer-style kimono), and enjoying Japanese street food, while appreciating fireworks that brilliantly light up the sky. There are also modern-day music festivals such as Summer Sonic and Fuji Rock which yearly attract crowds of music lovers from all over the world.
