I have started a new audio commentary on our website for certain items. However, I am sorry to say it is only in Japanese. So if you are able to understand Japanese, please give it a listen. The commentator is Nobuo Nakahara Sensei, who has over 46 years of experience in sword and sword fittings and has written many books on the topic. Nakahara sensei was born in 1951 and in 1974, he was introduced to Kosuke Murakami, a former director of the NBTHK, who studied under Honami Koson Sensei. He became independent after the death of his teacher in 1983, and published the study group newspaper "Touen" (bimonthly) until December 1998. Currently with 46 years of sword history, he is active as a lecturer and writer at sword appraisals and study sessions nationwide. His major works are "From the Muromachi period-Swords of Oita prefecture (2001)", "From the Muromachi period-Swords of Oita prefecture next volume (2008)", "People of the Honami family (2009)", "Appreciation of swords (2005)", "Standards for appreciation of swords (2019)". This audio commentary aims to convey the appeal of products that are difficult to express with text and images. We hope that the audio commentary will convey the appeal of products that are often overlooked and broaden the horizons of our customers. If you have the ability to understand the audio commentaries, I invite you to give it a listen.
