I saw a mention somewhere asking about the design of the now-destroyed [re-purposed?] Yasukuni Shrine Forge. I could not find anything on Google Search about the location, etc., so I took it upon myself to add a few mentions from Tom Kishida's outstanding book, The Yasukuni Swords: Rare Weapons of Japan 1933-1945; Tokyo: Kodansha, 2004; pp. 80-83.
