My Great Grandfather lived in Japan 1872-1875 and then visited more than a dozen times on business. I just found an autobiography that he wrote. There is a Japanese word that he uses several times and I cannot find a translation.
It is SAITORI. He says as the nobles sold their art works in 1870's to foreigners, a middle man (Saitori) would show the articles, and convey the offer to the noble - thus keeping the noble anonymous.
Is this word correct?
BTW, his capital S is "funny" like having dots at each end. I know he was fluent in Japanese and wrote the language also.
