Jingu-Gaien Fireworks Festival

Firework festival in the middle to Tokyo.
Cost: 7000 yen (stadium seat).
Free (outside)
Summer is the prime fireworks season in Japan. Some of the key events in Tokyo are Sumida River Fireworks, Tokyo Bay (Odaiba), and this one.
Why this one my favorite?
Simple. Plenty of bathrooms.
There are numerous benefits of holding fireworks festival at a professional out door baseball stadium.
— Crowd control. They know how to get people in and out of the place. There are multiple train lines in the area. It is possible to walk to Shinjuku or Shibuya stations.
— Stadium seating. Tight, but still better than sitting on grass. Also, assigned seating, so you don’t need to get there in the morning to save a seat.
— Beer served at your seat. That is right. The same staff that roams the bleachers during ball games does the same thing here. This sure beats other fireworks where there are huge lines at beer tents.
— Did I tell you that they have plenty of bathrooms?
Now I know that some will feel that I am snobbish for saying that fireworks festival that costs 7000 Yen per seat is the best. After all, there are plenty of other festivals, especially outside of Tokyo, where seating is free.
Yes, there is a charm in showing up 8 hrs before the show to lay down picnic tarp.
Yes, it could be fun to wait in a line for food, wait in a separate line for beer, and then getting lost because you cannot find where you situated your picnic tarp in the dark.
Yes, it is social to chat with locals as you wait in a big line for a portable potties.
Yes, it is quite exciting to see thousands of people heading to one train station in the town.
You miss out on all that «charm» at Jingu-​Gaien Fireworks Festival.
TIP 1: You can choose between the rugby stadium or baseball stadium. Choose the baseball stadium. Fireworks does up right next to this stadium.
TIP 2: I hate giving away this secret, but I will, because I am a good Unilocaler. You don’t have to sit at your assigned seat. The best seats are all the way at the end of third base side. You will see a section of open seats. They don’t sell these seats because it is too close to the fireworks. Ashes may drop on you (and it does). If you sit here, workers may warn you to go back to your assigned seats, but they do not enforce it.
TIP 3: If you like J-​Pop, go there early. Fireworks starts at 7:30, but live concert starts around 5PM. Past performers include Puffy, May J, Tamaki Koji, etc.
TIP 4: Bring your food and beer/​wine. Although there is a sign at the entrance that indicate no cans or bottles, that is only enforced for baseball games. They are afraid that people will throw bottles at players. For fireworks, they do not enforce such rule, so it is best that you bring your own booze. Bring a bottle of tequila if you like.
