I am afraid
it will be very hard (maybe impossible
) for you to find an online bead store here in Japan that is in English.
I am assuming you live in Japan - may I ask where ? and do you have a craft store in your locality ? If so - maybe you can ask them to order the items you need for you - for a small charge. Most online bead shops charge about 800 yen for shipping unless your order exceeds a certain amount which can be from 5000 to 10,000 yen which can be a LOT.
Another option is to find a Japanese friend who can help you out with your purchase online. I think this is your best bet.
Most online bead shops require pre-payment of your order before they ship out. Pre-payment can be done in many ways -
1. Bank transfer (ginkou furikomi
- bank to bank or post office to bank plus transfer charges depending on the amount being transferred and the bank or post-office; or via the convenience store.
2. credit card
3. Cash on delivery (daikin hikikae
?) - you pay opun delivery to the delivery guy (usually a surcharge of 300 yen or more)
You can check this site http://www.suzuranart.com/top.html
for a list of bead shops (click on Beads shops in the Japanese version of the page). You need a Japanese speaking friend for this. The list is classified according to area/prefecture - and the shops with web sites are also listed.
I hope this helps (i.e. only if you live in Japan)
