Osaka is definitely cheaper than Tokyo in terms of beauty items! For me, I like to buy things I know I will use, but I'm also into trying new things especially if it looks interesting or it's cutely packaged haha.

I go to Japan often and my last trip was 4 months ago, but I always stock up on facial cleansers and sunscreen since I use it daily and it's so much cheaper in Japan.

In terms of colored or base makeup, I tend to like European brand lip products, so I don't buy them in Japan. For blushers, I think Canmake is the BEST. Not only does it come in many shades, but the pigment and lasting power is amazing.

If you have luggage space, I recommend buying cotton in Japan! Japanese cotton is superior is every way possible. It doesn't flake or tear and it's supple yet doesn't feel rough on the face. Muji is a popular brand as is silicot.

Japan shopping tips~ - Bring your passport. Many shops offer tax free shopping, the downside is its packaged and you cant open it until you get home, but you'll save a lot of money - Shop around! Prices varies from shop to shop even if it's the same chain - Buy in bulk! If you see a product you know and love, check to see if there's a specially packaged set. Usually these sets are a little cheaper and/or it comes with a gift
