Tell me interesting things i could do in Tokyo?

Question:

I'll be in Tokyo soon and I would like to know some cool interesting and fun things to do ... and if it's free it's even better (I've got a low budget)

thank you all for your response

Answer:

I definitely recommend you visit the districts of Shinjuku, Shibuya, Ginza and Akihabara. Also visit the Meiji Shrine and Tsukiji Fish market, take a ride on the unimaginably busy Tokyo subway, and eat at any little ramen store you can find, they are great. A day trip to Mount Fuji is also worth it. Also, shopping on Takeshita dori is a must. Don't forget to pose with Harajuku girls in Yoyogi park and watch any sumo wrestling match you have time to see.
