Quick summary: Japanese is one of the world's most nuanced languages โ levels of politeness, context-dependent meaning, and a phonetic system that trips up first-timers. This guide cuts through the complexity to give you 30 practical slang words and phrases that will make your Japan trip smoother, more fun, and more culturally respectful.
Why Japanese Phrases Matter More Than You Think
Japan has exceptional English signage in major cities, and service staff at hotels and tourist spots often speak some English. But the moment you venture into a local izakaya, a rural onsen town, or a neighborhood ramen shop, Japanese becomes essential.
More importantly, Japanese people deeply appreciate any effort made to use the language โ even imperfect attempts are met with warmth and encouragement. A well-timed ใใฟใพใใ (sumimasen) or ใใใใจใใใใใพใ (arigatou gozaimasu) signals respect for the culture and earns genuine goodwill.

It's far safer and more natural than its alternatives and can even substitute for thank you in some casual contexts.

Things to Avoid
- Don't eat or drink while walking โ it's considered impolite in most of Japan.
- Don't tip โ tipping is not just unnecessary in Japan; it can actually cause confusion or offense.
- Remove shoes when indicated by a step-down (genkan) at the entrance of homes, many ryokans, and traditional restaurants.
- Don't speak loudly on trains โ quiet culture on public transport is strictly observed.
- Don't pass food chopstick-to-chopstick โ this mimics funeral rites and is considered taboo.
Pronunciation Tips for Japanese
- Every vowel has one sound: A = "ah," I = "ee," U = "oo," E = "eh," O = "oh." No diphthongs.
- Japanese R is not like English R โ it's a light flap, almost between R, L, and D.
- Long vowels matter: ใใใใ (ojisan) = uncle; ใใใใใ (ojiisan) = grandfather. The double "i" changes the meaning entirely.
- Silent vowels: U and I are often barely voiced between unvoiced consonants โ desu sounds like "des."
- Equal stress: Unlike English, Japanese syllables are roughly equal in length and stress.
