Just discovered in another message that AoW allows to play an ikko ikki army

I 've always loved Japanese armies AND mass units, soooo that sounds like the
perfect time to start building an ikko ikki army^^.
I would need some info concerning the amount of infantry i would need to get in order
to play a standard size army(knowing that i would rather go for the maximum amount of possible
units rather than fewer but better ones^^). Do they get any cav that i would need to buy too?
Hope that my request is not against any kind of code of conduct or anything:p.
p.s: sorry for the possible broken English... French here^^.
