Stayed in Tokyo for two days only and wish I can stay longer. Many places that I didn't make it to explore. I visited the Asakusa area especially Senso-Ji, Edo Tokyo Museum and I loved it, Akihabara and bought a pair of light saber chopstick, the beatiful Camii Mosque, the crowded Shibuya and Tsukiji Fish Market. I love the food in Tsukiji especially the Sashimi rice bowl with fatty tuna in it :)
Insider Tip:If you have JR Pass with you and you want to use subway services(Metro and Toei), buy the subway pass at Tourist Information Center at Haneda Airport (1,2 and 3 day pass). It really a great bargain if you go to many places with subway services.
