I my Precision Special (bought 2nd hand, but as new) came with a Fender Gig bag, Allen keys, guarantee card, Fender price tag (with barcode/model number) and a Fender cleaning cloth. Then again, this bass cost £599 new in 2001. So you'd expect some candy. The P Bass Upgrade I bought similarly as new, just came with a Fender gig bag.
My guess is that some MIMs come with candy, some don't. Some have their candy pilfered on way from factory to customer, some don't. So yeah, because of that people don't know what you're supposed to get, unlike with every US where you expect a hard case, strap, lead, manual, allen keys, truss rod adjuster etc.
What do you get with a Japanese bass when new?
