The typical path in Japan is shown by the education, training and experience of current workers above and in the Japanese guidance below. A detailed English guide for this occupation is being prepared.

Guidance from job tag (Japanese)
潜水士になるには、潜水士免許試験に合格しなければならない。試験は安全衛生技術試験協会で実施され、試験科目は、潜水業務、送気・潜降及び浮上、高気圧障害、関係法令の4科目である。受験資格には、学歴・性別など制限はないが、満18歳未満の人には潜水士の免許は与えられない。試験は学科だけで実技はない。
　スクーバ式潜水については民間のダイビングスクールなどで指導を受けるのも一つの方法である。その他各潜水方式とも、所属する会社で先輩から指導を受け、潜水技術を習得することが一般的である。水産・海洋系の大学・高校などで潜水に関する講義や実習を行っているところもある。
　潜水士の業務は陸上で行う作業をそのまま、潜水具を身に付けて水中で行うことが多く、潜水して行う作業についての資格や技能（溶接・溶断、発破、写真等）の習得も必要である。
　なお、潜水士の資格取得者のうち職業潜水士は約4,400人となっている（2024年時点*）。
