特急課金

• Reading: とっきゅうかきん
• Romaji: tokkyuu kakin
• Kanji breakdown: 特 (special) + 急 (fast, urgent) + 課 (charge, levy) + 金 (money) → express train surcharge (framed as in-app purchase)

Meaning

Express train surcharge — paying extra for a faster train, jokingly framed as a real-life in-app purchase.

A humorous slang that frames the express train surcharge using the language of mobile gaming. 課金 originally means 'charging' or 'in-app purchase' in gaming contexts. Applying it to train travel creates a playful metaphor: upgrading from a local to an express train is like paying to skip ahead in a game. The term reflects how gaming vocabulary has permeated everyday Japanese conversation, especially among younger speakers.

Examples

1. 時間ないから特急課金するわ。 No time, so I'm paying for the express upgrade.
2. 特急課金したら1時間早く着くよ。 If you pay for the express you'll get there an hour earlier.
3. 今月旅行で特急課金しすぎた。 I spent way too much on express upgrades during my trips this month.

Don't Say
