Catchphrases & Misc

Introduction

Some Japanese slang doesn’t fit neatly into any category. 知らんけど (I don’t know though) is a Kansai export that’s gone national. ワンチャン (one chance = maybe) has become essential for hedging any statement.

This chapter collects the catchphrases, filler words, and miscellaneous slang that every Japanese learner needs to know.
