He studied English under Ranald MacDonald, and as “Chief Dutch Interpreter” was one of the chief men involved in the negotiations with Commodore Perry in regard to the opening of Japan to the outside world. Williams, a member of Perry's second visit noted in 1854:

He ^* giving us all a good impression of his education and breeding. (Williams, p.120, March 3rd 1854)
