so my weeb ass is finally going to Japan. Main things me and my partner want to do are Ghlibi museum and theme park, see the life size Gundam, and go to a baseball game. We'll be mostly in Tokyo and Kyoto and then the Ghibli theme park in Nagoya. We like all the nerd shit so we'll be in Shibuya, Shinkuk and Akihabara, and maybe do some fancy stuff in Ginza.
Go see some wrestling at Korakuen Hall - I had to go there as a wrestling nerd pilgrimage and happened to get to an anniversary show of a decently-popular wrestler, but they run shows like every night of the week so you could just pick one any time.
Here's the schedule - i'm sure me and a few others could give you a rundown on some of these promotions.
Hint: the Joshi (women's) promotions hit fucking harder than the men most of the time. Every cool wrestling move you've seen in the last 20 years was invented by a Japanese woman.
Korakuen is also part of the Tokyo Dome City, so there's all the other stuff to do surrounding it too (the rollercoaster, shopping centre & restaurants, the Baseball HoF/museum, the Dome itself for tours and baseball if you're lucky)
