Yup that's about the best case for buying from Japan. Also big is anime, high end fishing gear (reels and lures are perfect because they're so shippable) also golf clubs (length can be a shipping challenge). Also look into zenmarket.com for a proxy buyer / forwarder

It being a proxy buyer means they don't really support you with issues (at least from my experience using it once). I purchased a guitar for several hundred EUR (before shipping and taxes), and it was described as functional. It arrived relatively quickly and was extremely well packaged.

However, the seller either didn't know or hid an issue. Zenmarket provided 0 support. I think they just google-translated my message, forwarded it to the seller, the seller just said "item as-is, no partial refunds", and Zenmarket just closed the issue.

For the guitar nerds: the neck was back-bowed, and it was not really playable because several frets were already buzzing. Truss rod arrived completely loose, meaning fixing this would be difficult/expensive. Try to explain to a tired customer support person that it makes some kind of sound, but not the right kind.
