ワリカン

• 読み: ワリカン
• ローマ字: warikan
• 漢字の分解: From 割り勘定: 割り (to divide, split) + 勘定 (account, bill) → split the bill. Shortened to ワリカン in casual speech
• 発音: /wa.ɾi.kaɴ/

意味

Splitting the bill equally among everyone in the group, regardless of what each person ordered.

ワリカン is the default approach to paying at group meals in Japan, especially among friends and colleagues. Unlike Western 'going Dutch' where each person pays for what they ordered, Japanese ワリカン typically means dividing the total bill equally. This is so ingrained that many izakaya have ワリカン buttons on their payment terminals. However, generational and gender norms around ワリカン are shifting — younger couples increasingly split bills, while older norms expected men to pay.

例文

1. 今日のご飯はワリカンでいい？一人3000円くらいだと思う。
2. デートでワリカンってあり？なし？って話、永遠に終わらないよね。
3. ワリカンなのにめっちゃ高いもの頼む人いると正直モヤる。
