Re: When did the word "Aiki" first appear?
Good point Cliff, the turn of the century kanji (19th to 20th) were much more 'difficult' and chinese-like, making documents 60 to 70 years hard for current native reader - not impossible, just 'difficult.'
Another phrase pops up - 合氣術 which translates as "Aiki technique or skill." This is a 1920 reference.
"A translator, a translator, My aiki for a translator."
