Hanabi festival (花火大会) falls in between late july and early august. There's practically a firework display every other day somewhere in Japan.
Its a tradition to wear bathrobes (Yukata 浴衣) and picnic when u watch the fireworks.
Here we are.. me and my labmates. Quite "kiasu", we reach the picnic spot 3 hours before the start of the fireworks just to secure a good seat.
Here are some unique ones. They come in various shapes - heart shape, ghost, jellyfish, cat face, flying saucer, butterfly, mushroom, spiral etc etc. Indeed impressive.
