肩代わり
Taking over someone else's burden, responsibility, or debt.
The term "肩代わり" means to assume someone's financial obligations or debts, showing a financial responsibility shift.
彼の借金を肩代わりした。
I took over his debt.
Here, the term "肩代わり" expands its usage to include taking over responsibilities, not necessarily financial.
彼はそのプロジェクトの進行を肩代わりすることになった。
He agreed to take over the progress of the project.
In this case, "肩代わり" refers to assuming managerial duties or operational responsibilities.
