My research resulted in the following preliminary conclusion, please correct me if I'm wrong: If you ask experienced collectors, you can summarize that the Nihonto market has changed and
has become more acute, especially in recent years: Especially the market for high-quality, fairly priced objects seems to be completely empty .
Furthermore the interesting stuff always remain in Japanese hands and is traded only among long-standing collectors and networks (understandable). Even Tsuruta-san (AOI), which has a great selection in terms of quantity and
is accessible to Europeans, is said to be in the 3/10 to 6/10 range in terms of quality. Basically, as a nobody, you always lose out in this niche area "nihonto", especially since the majority get their blades over the Internet
without being able to take advantage of the chance to look at the blades in real life (and photos are of course placed in such a way that kizu and rust cannot be clearly seen, or are even covered up with a horimino).
Of course it's not just about owning the great works, but when you read and hear that only "junk" is being exported to the West, then you start to question your passion, at least for your own possessions.
Buying directly in Japan also doesn't seem very tempting when you add up to 35 percent more for transport and customs clearance (Germany and Switzerland). Thanks for your assessments of the current market situation and potential future developments.
