Japanese jewelry

I hadn't had the opportunity to buy it myself so I want to buy some nice things online.

I'm looking for earrings or necklaces, can be silver (not gold due to allergy!) but simple stuff is okay too.

What I mean by 'Japanese' is not the designers name but e.g. earrings with a little sushi, a fan, a katakana/hiragana/kanji letter, an ukiyo-e design etc.

I only found one shop (www.jun-gifts.com) but their range in choices is limited.

Anyone who knows a reliable online store where I can buy some of this?

Do you mean something like this? It's only in Japanese language but I hope it helps.

@ Bobo, yes that's an example of what I mean. But I can't read the Japanese.... :(

Anyone, please?
