ラッシュ

• 読み: ラッシュ
• ローマ字: rasshu
• 漢字の分解: From English 'rush (hour)' → katakana loanword for peak commuting period
• 発音: /ra.sɕu/

意味

Rush hour — the peak commuting period when trains and roads are at their most congested.

Borrowed from English 'rush (hour),' ラッシュ in Japanese specifically evokes the extreme congestion of morning and evening commutes. 朝ラッシュ (morning rush) and 夕ラッシュ/帰宅ラッシュ (evening/homeward rush) are daily realities for millions. Beyond trains, ラッシュ also applies to highway congestion, especially during holiday periods (お盆ラッシュ, 年末年始ラッシュ). Avoiding ラッシュ is a key consideration in daily planning.

例文

1. 朝ラッシュ避けたいから早めに出るね。
2. お盆のラッシュに巻き込まれて高速3時間渋滞だった。
3. ラッシュの時間帯は電車乗りたくない。

使い方ガイド

場面: commuting, travel planning, daily conversation

トーン: practical, complaining

正しい言い方

• ラッシュの時間ずらして出よう。 (Let's leave at a time that avoids rush hour.)
• 朝ラッシュ終わってから行けば空いてるよ。 (If you go after morning rush is over, it'll be empty.)

避ける言い方

• 深夜のガラガラな電車を「ラッシュ」とは言わない — ラッシュは混雑した時間帯のこと (Don't call an empty late-night train 'rush' — ラッシュ means a congested peak period)

よくある間違い

• Thinking ラッシュ only refers to trains — it is also used for highway congestion during holidays (お盆ラッシュ, GWラッシュ)
• Not knowing peak times — morning rush is roughly 7:30-9:30 AM, evening rush is 5:30-8:00 PM

起源と歴史

From English 'rush (hour).' Adopted into Japanese during the post-war period of rapid urbanisation. Often used without 'hour' — just ラッシュ alone conveys the full meaning of peak congestion.

文化的背景

時代: Post-war urbanisation, ongoing

世代: All commuting ages

社会的背景: Universal urban life

地域メモ: Most intense in Tokyo and Osaka. Holiday ラッシュ on highways and trains is a seasonal news staple, with predictable peak congestion around GW, Obon, and New Year.
