A yakatabune is a narrow, flat and long Japanese-style wooden boat that has historically been used to hold parties. Friends, families, and even coworkers might rent a yakatabune to socialize over a scrumptious feast for a special occasion. Nowadays, it is a popular bucket-list activity among international visitors who wish to experience this Japanese custom that dates back hundreds of years.
The Sumida River that flows through central Tokyo is one of the most popular places to hop on a yakatabune, especially during the fireworks season in summer. Prices will definitely be higher than other times of the year, but you basically get VIP seating to watch the firework displays up close. Otherwise, you would have to get to the venue hours in advance where you will hopefully find a spot, and even if you do, navigate through the intense crowds. With the comfort and privacy of the boat as well as delicious food to keep everyone in an excellent mood throughout the evening, I would highly recommend looking into reserving a yakatabune if time and budget allows.
