Delicious in Japanese
Today for those who want to know how to say Delicious in Japanese, I will introduce the four most common ways, from formal to casual or slang.
First, Oishii (pronunciation), also spelled Oishi, is the most common and formal way to say Delicious in Japanese.
You can use the politer version Oishii-Desu (おいしいです) (pronunciation) in every situation without hesitation.
Next, Umai (pronunciation), whose antonym is Mazui (不味い: meaning Taste bad), is another common way to say Delicious/Tasty in Japanese.
But Umai is less formal than Oishii and not recommended to use with people you don’t know. Also, this phrase tends to be more often used by males than females.
Short for Umai, Uma (pronunciation) is a casual way to say Delicious in Japanese.
As we often use this expression among male friends or family members, it is inappropriate to say Uma to strangers.
Last, Yabai (pronunciation) is a Japanese slang word often used by young generations, which can mean Delicious.
Yabai is a contronym or a word with opposite meanings; Dangerous & Awesome, and it can also mean Taste very good.
