Sounds like you are looking for irons actually made in Japan. Truth of the matter these days are that Japanese brands have offshored most of their manufacturing to overseas. (mostly China and Taiwan. ) Some honest brands actually mention that only the final assembly are done in Japan and the components are made elsewhere. Other brands are still hiding the fact that their stuff come from overseas countries and try to make it sound like it is made in Japan. Now... are the Chinese made and Taiwanese made irons bad? No not at all. If you think about it, 99% of the PGA players are playing these Chinese made or Taiwanese made irons and making gobs of money when then win. Looking at your list, most of the models are Game Improvement type irons which are most likely made outside of Japan. Some manufacturers still make their one piece carbon steel forged irons in Japan. But even those are becoming rare and harder to find. I know that Yonex makes some of their forged irons in Japan. Miura Giken also another brand that still forges their heads in Japan. Kyoei and other boutique brands have forged irons made in Japan too.
