Looking for Bulk Jewelry Supplies in Japan

Hi,

I live in Japan and I'm looking for recommendations on where to find products for a small online business I'm starting. It’s a handmade jewelry store with a Y2K fairycore theme, and I'm looking for sellers that offer raw materials like charms, beads, and similar supplies, ideally at lower prices or in bulk. I’ve attached a picture of a necklace to show the kind of style and materials I’m aiming for.

Any suggestions would be super helpful. Thank you in advance.
