確認する
かくにんする·kakunin suru
Meaning
to confirm; to check; to verify; to make sure
Nuance & Usage
確認する means to check something to make sure it is correct or as expected. ご確認ください (please confirm/check), 確認が取れた (confirmation obtained), 身元を確認する (to verify identity), 予約を確認する (to confirm a reservation) are everyday uses. 再確認する (saikakunin suru — to double-check, reconfirm) and 確認作業 (kakunin sagyou — confirmation/verification work) are used in professional settings. In business emails, ご確認のほど、よろしくお願いいたします is a standard closing phrase when asking for a check or approval.
Common Mistakes
Learners sometimes confuse 確認する with 確かめる (tashikameru — to make sure/verify, more personal and direct) and チェックする (chekkusuru — to check, casual loanword). 確認する is the standard formal choice in professional contexts. 確認が取れる (to get confirmation) and 確認が取れない (unable to confirm) are useful patterns. ご確認いただけますか (Could you please verify this?) is a softer, more polite alternative to ご確認ください in business emails.
