チーム
ちーむ
chiimu
= team
チーム (chiimu) is the word you will hear the moment people start working, playing, or competing together in Japan — on the field, in the office, or inside a video game lobby, this borrowed English word has become the default way to say (team).
チーム comes directly from the English word (team), and its long vowel is written with a dash: ち + ー + む, read as a stretched-out chiimu rather than a short chimu. It shows up constantly as スポーツチーム (sports team), and just as often in offices as a 開発チーム (development team) or プロジェクトチーム (project team). Two compounds built on it are essential: チームワーク (chiimuwaaku, teamwork) describes the cooperative spirit itself, while チームメイト (chiimumeito, teammate) names a fellow member. Japanese also has older native words covering overlapping ground: 組 (kumi) means a group or class, often used for school classes or small fixed groupings, and 班 (han) means a squad or work detail, common in schools and factories. Neither carries the modern, dynamic, goal-oriented flavor of チーム, which is why 組 and 班 tend to describe who you are grouped with, while チーム describes a unit actively working or competing toward something together.
Learners often reach for 組 or 班 when they mean チーム, but the two are not interchangeable: 組 (kumi) suits a fixed school class or long-standing group, and 班 (han) suits an assigned squad for a specific duty, while チーム is the natural choice for anything competitive or project-based, from a soccer club to a startup’s engineering unit. Do not shorten the long vowel — it is chiimu, not chimu, and mispronouncing it is a common beginner slip. Learn チームワーク (chiimuwaaku, teamwork) early, since it functions almost as a value word in Japanese workplaces and sports, praised on its own even when a team loses. Also useful: チームメイト (chiimumeito, teammate) and チームプレー (chiimupuree, team play), used to praise someone for prioritizing the group over individual stats.

In Japanese sports culture, チームワーク is often treated as more important than any single star player’s performance. Baseball and volleyball broadcasts frequently praise a team’s 連携 (coordination) and willingness to sacrifice individual glory for the group, and youth sports coaching puts heavy emphasis on players learning to move and think as a チーム before focusing on personal skill. Losing with strong teamwork is often described more positively than winning through one player’s dominance.
This same value carries directly into the Japanese workplace, where a チーム is expected to share credit, coordinate closely, and avoid standing out as an individual at the group’s expense. Companies frequently name internal units プロジェクトチーム or 開発チーム rather than using the older 班, since チーム carries a modern, collaborative, goal-driven connotation that fits corporate language. Meanwhile 組 and 班 have not disappeared — they persist in schools, factories, and traditional organizations — showing how a borrowed word and native vocabulary can comfortably divide up the same conceptual space depending on context.
