it is a decent price if it is the hammer price.
it is a "Made in Japan" version, suppose to be rarer than the usual " Made in Taiwan R.O.C.".
i believe the Japanese always keep the "Made in Japan" version (and some unique designs) for sale in Japan only, at least in their golden era of bubble economy,
and all the export versions were Taiwan made.
i have a black "made in Taiwan R.O.C.", i wouldn't mind paying this amount to own this.
...oh, no relation.
