More about pronounciation-- the good doctors name-- Dr. Tsunoda's- has the TS-- which to people who haven't learned it in childhood -- sounds just like S-- but Suyuki and Tsuyuki in Japanese are as different as Brined and Blind-- words my Japanese brother- in -law "hears"(an pronounces) the same.--as brined
(or brineds-- as in "we got some venitain Brineds for the window.")-- but most adult learner of English (or Japanese) have trouble with one (or the other!)

Just as i can't say Tsuyuki right-- he has trouble with Blind/brined. This ability to hear certain sound used in a language disapears young-- before the age of five-- So my bi-lingual neice and nephew can both say their name, and say blinds! (or say brine-- when speaking about the taste of sea water)
