How to say "upon" in Japanese
Choosing the right word
- expressionNot a general word for 'upon': it is used only in place names, where it simply reproduces the English preposition in Japanese script. Outside such names it is seldom the word you want.
- 次第しだいsuffixCovers the temporal 'upon' — when something happens as soon as, or immediately after, something else. This common word is the ordinary choice for that sense, expressing that one action follows right upon another.
For the temporal 'upon' (as soon as, immediately after), use 次第; 「アポン」 appears only in place names, reproducing the English preposition, and is rarely the word a learner needs.
