Where can I buy Japanese food/drink products?

Question:

About a year ago, I came across a site where you could by food products from Japan/Korea; however, I can't remember what the site was called.

I remember seeing that you could buy drinks like Pepsi Nex and whatnot. Anyone know a site where I can purchase drink and food products from Asia online?

Answer:

If you live in the UK there is an online Japanese shop (food).
www.japancentre.com
I used to shop there regularly but now we moved to India and they don't deliver here.
