how can I ask about things I dont know

When I asked about campy outrageously over the top things to see in Japan, (like Puroland or Disney world) someone mentioned the Akihabara maids. Now I have never even heard about, ever, these maid cafes. I would never have even dreamed of looking these up on the net until someone here mentioned them! How many other zany, kooky things are out there that I don't even know to ask about or search for? If you know of anything over the top please tell me. I now know about Yoyogi on Sunday, the Akihabara maids and Puroland. Anything else please?
How can I be an audience member on those crazy constestant shows etc?
what is the Tokyo Takazaruka theatre?

An internet search for "Takarazuka theatre" should provide a lot of information...

Also try searching "weird Japan", "kooky Japan" etc as there is lots written about that kind of thing.

And maybe also by keeping one continuous thread on the topic, so that people who come here would get an idea of what kind of things you are looking for... :)

Takarazuka is the all-female theater group. The original theater is in the city of Takarazuka, and the Tokyo theater is a branch theater. The shows are fun, but of course, they are in Japanese.

They have a lot of interesting ''theme'' restaurants. Here are a few of the popular ones:

Ninja Akasaka (Ninja themed):

The Lock Up (A jail-themed restaurant)

Oh, here is a list of some:

A lot of people find them to be quite fun (but expensive!)
