Senpai and Kohai: Seniority in Japanese Sport
Senpai and Kohai: Seniority in Japanese Sport
The senior-junior relationship shapes every Japanese team. Here is how senpai-kohai works in sport — its strengths, its tensions, and how it’s changing.
Step into almost any Japanese sports team and you meet the senpai-kohai system — the structured relationship between seniors (senpai) and juniors (kohai). It shapes how teams train, behave and bond. Here is how it works, and the debate around it.
1. What it is
A seniority hierarchy.
Senpai-kohai is a hierarchical mentor relationship rooted in Japanese society: juniors show respect and learn from seniors, while seniors guide and look after juniors. It runs through schools, workplaces and especially sports clubs.
2. In the sports team
Roles and rituals.
In a club, kohai traditionally handle tasks like preparing equipment and tidying up, address senpai with respect, and learn the team’s ways from those above them — part of the etiquette explored in our guide to rei and respect.
3. Strengths and tensions
Order and its limits.
At its best, the system builds discipline, mentorship and team cohesion. At its worst, rigid hierarchy can enable excessive deference or even bullying — a tension increasingly discussed in Japanese sport.
4. A changing tradition
Respect without rigidity.
Modern Japanese sport is rethinking the harsher edges of senpai-kohai while keeping its positives — mentorship and mutual responsibility — in line with a more player-centred coaching culture.
