Affordable Ring Repair Places in Tokyo?

So I have this brass ring that broke into 2 pieces, and I want to repair it properly. Does anyone know places that offer such services for an affordable amount?

"Just get glue from the 100 yen store", yes that's my current stopgap solution, but it's noticeable and still prone to breaking again. I want to properly repair it this time.
