Yamazaki 18 help

wrldtrvler0203

Hi everyone. New member here. I’ve acquired a couple bottles through the passing of a relative. One of them I have a few questions about. I’m trying to determine the release date of a Yamazaki 18.  This particular bottle is numbered and most text is in Japanese. I’ve seen plenty of these bottles through searches but very few are individually numbered with a 6 digit number on the bottom right of the front label.. Any insights are very helpful. Thanks!
