Everything you ever wanted to know about Tokyo, you smelly weeaboo, you.

ramen stands and places that sell food like yakitori and stuff are cheap. The convinience stores are really good, they sell all sorts of food at am/pm prices.

Also, the rails are the best method of transportation so get a Suica card. It's better than using the machines to buy a pass every time. All you have to do is swipe it on the gate things.

If nowhere to sleep, either pay for homestay (if you can find it) or rent out love hotels by the night. They're like 50/70 bucks but be prepared to find used condoms in drawers if it's a supercheap place.

If you go to disneyland, don't go inside. Hang out around the outside and they have their own downtown disney. It's not cheap there but it's fun to look around. They have a movie theater too. If you really wanna go to d-land, go to disney sea, it's much better than the other park.

Go to odaiba bay as well. More stuff to see. and there's like cool arcades with claw machines and stuff. Go to yoyogi koen at harajuku and you can look at all the weird goth lolita girls and more weird people and that's free. They have a lot of streetside food vendors too.

Shibuya has some cheap stuff because it's designed mainly for teenagers, and the girls there all look like anime characters (cosmetic surgery) the night clubs in shinjuku are not that pricey.

akihabara is really fun to look around. You get to see Japanese Nerds. They're the OG weeaboos. Maid cafes are not that expensive and fun to go to once or twice. They also sell cheap electronics.
