Doink: A few reasons-
1. Seller and another unrelated party confirmed they were Japanese, mostly based on the design of the inside of the wheels where the tyres are mounted (i.e. curved with one distinct crease, vs. Taiwanese / Malaysian designs where the inside of the wheels are usually flat)
2. 'JAWA' (Japanese alloy wheels association) sticker, with Japanese writing, heheh.. ;p
Wanggot: Rims were sold earlier today, sorry mate..
