This is "Kinnanzan" from Kobaien, a long-established ink maker founded in the Azuchi-Momoyama period, the oldest in Japan. It is a masterpiece made from ultra-fine, high-quality rapeseed oil soot, and Kinnanzan is one of the most highly-regarded inks. This is an old ink made in 1978, and I believe it is a rare ink. As it is an antique, I would be happy to sell it to someone who understands this. I am also selling Kobaien's safflower ink.
