Your Top 3 must do things ?

Our first trip to Japan will be next March, im still in the early stages of planning out what to do/see/visit etc.
If you had to pick 3 things in each of the following locations that you thought were must do's what would they be.
Tokyo
Osaka
Kyoto
include anything you want, day trips, things to see, places to eat/drink, shops, areas to walk around, parks etc etc, no exclusions.

I don�Lt know much about Kyoto; I�Lm also on my early stages on planning, to go on May-June next year.

Tokyo:

1. Breakfast Sushi in Tsukiji
2. Spend a whole evening playing rare arcade machines
3. Ride the rollercoaster @ Tokyo Dome park

Osaka:

1. Visit de Aquarium
2. Go to Super Potato shop at Den Den Town
3. Watch a baseball game

Kyoto:
1. Fushimi-Inari Taisha
2. Kiyomizu-dera and its surrounding histori-tourism district
3. Nishiki Market during the day

Osaka:
1. Bunraku
2. Takarazuka
3. ? (I haven't spent much time in Osaka)

Tokyo:
1. Kabuki in Ginza
2. Walking from Meiji-jingu through Harajuku
3. Ameyoko in Ueno

For Tokyo...

1. Spend some timebin the colourful weirdness that is Akihabara.

2. Walk in my fave park, Shinjuku Gyoen.

3. Visit Ueno park, it has a host of great museums and galleries within it.

I second Albert with a few changes
Kyoto:
1. Fushimi-Inari Taisha
2. Kiyomizu-dera and its surrounding historical-touristic district
3. Nishiki Market in the morning and the other adjacents arcades

Osaka:
1. Bunraku
2. Umeda sky building
3. kita giant underground malls : Hankyu san ban gai, Whity, Diamor (all connected)
Takarazuka is close to kobe by the way and they do not play all the time so it is a hit and miss

Tokyo:
1. Kabuki in Ginza
2. Walking from Meiji-jingu shrine through Harajuku
3. Ameyoko in Ueno (then visit Ueno Park for the shrines, museums etc.)

Great ideas everyone, its interesting to see how different people from different cultures enjoy doing different things.
