“No Bo-hi” Bo-hi is the grind ridge seen the full length of a sword. I’m not sure why you’ve said there is none..
As far as import export, In Japan if you wish to import hunting rifles, air guns, and swords, you need to obtain a possession permission from the Prefectural Public Safety Commission. Possessing weapons is fundamentally prohibited under the Firearms and Swords Control Act any blade over 14cm is confiscated and destroyed without the proper paperwork, export same, proper paperwork.
Only traditionally made Nihonto can be licensed, i.e. swords made in Japan from Tamahagane 玉鋼 (and Shinto swords that are inscribed "Motte Namban-Tesu 以南蠻鐵" ["made using steel from the southern barbarians"]). This means in effect that it has to be either an antique, or made by a contemporary, licensed smith. Mass produced WWII swords (so called Showato昭和刀) and foreign made swords are not eligible for Torokusho.
Tomahagne, yes manufacturing did take up again after China & US left Japan, but that’s not about his sword… Mid 1800’s Emperor Takamori orders Samurai to be disbanded and all sword production to cease. 1937 China’s turn, 1945 US & China confiscate and destroy swords.
Contemporary smiths have to go through an apprenticeship of at least five years and - after they have proven their ability to forge a sword before a panel of judges consisting of senior smiths - and become certified by the Cultural Agency (Bunka-cho 文化庁).
I’m sure you’re additional information was welcomed, the blatant disrespect however was not.
