Oishii and Umai: Saying Delicious in Japanese

Oishii and umai both mean delicious. Oishii is the standard, polite, universally safe word. Umai is more casual, sounds direct and hearty, and has traditionally had a masculine image, though plenty of women use it among friends today. Umai has a second meaning too: skilled. This guide covers when each word fits, the reaction words that surround them, what to say at a host's table, and how to politely say that something is not to your taste without the blunt mazui.

Oishii is standard and safe with anyone; umai is casual and hearty

Umai also means skilled, as in e ga umai, good at drawing

Oishisō means looks delicious, the natural reaction before eating

Chotto nigate desu is a gentle way to say you do not like something

Two words for delicious

Oishii is the default. It works in every register, from a child's lunchbox to a formal banquet, and adding desu makes it polite enough for anyone.

Umai says the same thing with more force and less polish. It is the word shouted after the first bite of a great bowl of ramen, and it often shrinks to a single clipped syllable in excitement.

JapaneseRomajiMeaning
おいしい!Oishii!Delicious!
おいしいです。Oishii desu.It's delicious: polite
うまい!Umai!So good!: casual
うまっ!Uma!Wow, good!: very casual, excited

Choosing by situation

The choice depends on who is listening more than on the food. Umai belongs with friends, family and casual places; oishii works everywhere, including those places.

Umai has traditionally carried a masculine image, and some listeners still associate it with men. Many women use it casually now, but if you are unsure, oishii never sounds out of place.

Umai also means skilled

Umai has a second, completely different meaning: good at something. In that sense it is often written with different kanji, but in speech the context tells you which meaning is intended.

The adverb umaku, well or successfully, is extremely common and worth learning early.

JapaneseRomajiMeaning
絵がうまいね。E ga umai ne.You're good at drawing
うまくいった!Umaku itta!It went well!
うまく言えないけど……Umaku ienai kedo…I can't put it well, but…
説明がうまいですね。Setsumei ga umai desu ne.You explain things well

Oishisō and other reactions

Japanese reacts to food at every stage: when it is seen, when it is smelled and when it is tasted. Having a phrase for each stage makes you a much more pleasant person to eat with.

JapaneseRomajiMeaning
おいしそう!Oishisō!That looks delicious!
いい匂い。Ii nioi.It smells good
本当においしいです。Hontō ni oishii desu.It's really delicious
これ、やみつきになる。Kore, yamitsuki ni naru.This is addictive
優しい味ですね。Yasashii aji desu ne.It has a gentle, comforting flavour

At someone's table

Eating a meal someone has cooked for you calls for more than one oishii. Asking a small question about the dish shows genuine interest, and it keeps the conversation going naturally.

JapaneseRomajiMeaning
いただきます。Itadakimasu.Said before eating
とてもおいしいです。Totemo oishii desu.It's very delicious
これは手作りですか。Kore wa tezukuri desu ka.Is this homemade?
作り方を教えてもらえますか。Tsukurikata o oshiete moraemasu ka.Could you teach me how to make it?
ごちそうさまでした。Gochisōsama deshita.Thank you for the meal

When it does not taste good

The opposite of oishii is mazui, and it is blunt. Said about someone's cooking it is hurtful, and it also means that is bad news, as in mazui, okureru, uh-oh, I will be late.

Polite Japanese shifts the focus from the food to your taste. Nigate, something you are not good with, is the key word.

JapaneseRomajiMeaning
ちょっと苦手です。Chotto nigate desu.I'm not very good with this
私には少し辛いです。Watashi ni wa sukoshi karai desu.It's a little spicy for me
独特の味ですね。Dokutoku no aji desu ne.It has a unique flavour
もうお腹いっぱいです。Mō onaka ippai desu.I'm already full
まずい、遅れる!Mazui, okureru!Uh-oh, I'm going to be late!

FAQ

Frequently asked questions

Is umai rude?

Not rude, but casual. Among friends and at casual restaurants it is perfectly natural. At a formal dinner, with a host's family or in front of a client, oishii is the safer word.

Can women say umai?

Yes. Umai has traditionally had a masculine image, and some people still notice that, but many women use it casually today. Oishii is neutral for everyone.

How do I say something is not delicious politely?

Avoid mazui, which is blunt. Say chotto nigate desu, I'm not very good with this, or watashi ni wa sukoshi karai desu, it's a little spicy for me, to focus on your taste rather than the food.

What does oishisō mean?

It looks delicious. It is the natural thing to say when food arrives or when you see it, before you have tasted it.
