I've had 2 basses from Japan, one from Ishibashi and another from a large ebay based outfit but I cannot remember their name.
And a bunch of pedals.
No problems with any order. The Ishibashi bass was a Japanese market Fender P bass (PB-62 or something?) and was actually in even better condition than the sales blurb claimed. Obviously like an idiot I sold it because at the time I didn't understand P basses.
My most recent Japanese buy was from Effects Bakery - they make tiny budget pedals. I bought their "Japanese Butter Roll" vibe and it arrived in under a week, was under the import fee point and vat was dealt with so got to be for about £50 including the shipping.
