Where to buy Japanese cosmetics in the UK?

As per the title really. My Japanese girlfriend will be coming to the UK on a fiancee visa shortly and it would be good to know where she can buy these things from.

We're just outside London, so hoping that there might be some specialist shop there which might sell them. Failing that, a good online retailer would be perfect.

Many thanks for any replies :)

Try Mitsukoshi department store near Piccadilly.

Alternatively, buy online from jshoppers, DHC UK or sasa.com.

You may be able to put in a special order through Japan Centre.

sasa.com is really popular! I have purchased from them multiple times(Japanese products too). Otherwise, if she uses really big brands, then their official site might even ship overseas.
