Regarding the Japan version and Asia version, yes, Japan version means the stock came from Japan. So, that means China > Japan > Malaysia. Asia version = from Shanghai, or HongKong, or Singapore > Malaysia. Companies like Good Smile have a main distributor in the 3 countries/cities i mentioned. So, if you ordered your figures from HS, HLJ, AmiAmi, etc, they are all Japan version.
And, all Japan versions of scale figures by Good Smile, Max Factory (and Alter also if not mistaken) will have a shiny sticker behind or bottom of the box, which reads hentai japan (HJapan). The sticker will not be there for Kotobukiya, Alphamax, etc (most other brands) regardless of what "version".
But, if you bought your new figure from an event where Good Smile has a booth - like AFA, Culture Japan, etc whether the stock is Japan version or not, we cant be sure (to be honest, i dont think it is - transport/shipment is expensive).
NO sticker will be present on the box of figures sold in such events, but not necessarily because they are not Japan version; it's because the stickers are slapped on by traders and distributors (like AmiAmi) in Japan, not by Good Smile. But, let's give an example of AFA singapore - does the figure come from Japan or their own S'pore distributor center? The Singapore distribution center is the bigger possibility for me but we cant be sure our selves. If Good Smile themselves is selling Asia versions in their booths at such events, why worry about the quality difference with Japan versions?
Hence, does Asia version or Japan version really matter? Not a big deal. But, it is true that Japan version figures underwent quality inspection a 2nd time in Japan so some people feel better or more assured that the quality is better. The first time QC is done is in the factories in China. However, quality issue itself is still highly dependent on luck. But why sellers like AF Hobby made a big deal out of Japan and Asia version and price them differently? Supply and demand - people asked for it. Some people are too particular about Japan version, and there are also those who wants to save more and pay less so they dont mind Asia version. So, AF pretty much went through the trouble and take stocks from different suppliers and label them differently to satisfy people who are particular about versions. So, they can target customers with both kinds of preferences.
So, is it means that for those RM480 is asia version...and RM560 is Japan version?
