Condoms in japan , who?

Question:

who is supposed to buy it? the male or the female? in western culture the guy buy it but japan is so different so.. and then, where is is possible to buy condoms? i've never seen condoms in supermarket , and nether in the automatic machines (only beverages and sometimes newspaper).
And if someone know the average price of a pack of 10 condoms in Japan, thanks!

Answer:

It's usually sold at a drug store like Matsumoto Kiyoshi.

Usually a boy buys it because it's something a boy uses. But of course, girls buy it in some cases. It depends on each case.
