「一生懸命」と「一所懸命」の使い方は同じでしょうか？
Both 一所懸命 and 一生懸命 are currently in parallel use to mean _endeavoring with all
one’s might_. The former literally means _to risk one’s life “at a place” for
achieving something_ , while the latter means _to do something at “a risk of
one’s life” for achieving something_.

Though 一所懸命 and 一生懸命 are used in the same meaning, 一生懸命 was derived from 一所懸命,
which originally meant that 武士 – Samurai – in ancient times survived by
desperately defending their fief given or assigned by the Mikado or Shogun
against invaders.

Both words are used interchangeably today because they sound almost the same
and the concept of risking life on defending one's territory is no longer
relevant to the people of today.
