I have often wondered the same thing. My ball marker is made for japan that I got on ebay and matches my putter grip and head cover, but for some reason its not sold in the US.

We'll guys Yes i'll agree japan dose have some cooler bags. I live here in japan and i see them all the time. Titleist dose have a Japan division and  the japanese Market is very big for golf. And let me tell you. You dont want to pay japanese prices for golf stuff. ProV's are about 70 U.S. dollars. the new Titleist Driver try over $500 after the conversion and thats with a Titleist shaft in it. Japanese are huge on aftermarket shafts so you'll find some for $700. I just saw a Used set of 710 MB irons 5-pw. try $800. a Mid size  Staff bag goes for around $300. But it is pretty cool its a glossy paten leather bag. I still order my stuff from the U.S. even after shipping its cheaper.
