How to say "high" in Japanese

Choosing the right word
  • 高いたかいJLPT N5approx.Common
    i-adjectiveThe adjective for physical height: tall people, high buildings, mountains, ceilings. When you simply want to say that something is high or tall, this is the word you want.

    Mt. Fuji is the highest mountain in Japan.
  • ハイCommon
    na-adjective, nounThe loanword for the emotional sense of 'high': feeling euphoric, elated, or intoxicated, as from alcohol, drugs, or excitement. It does not describe physical height.

    I kept saying "Let's stop" but she drained cup after cup of wine ― and now, as you can see, she's completely drunk.
  • 高尚こうしょうJLPT N1approx.Common
    na-adjective, nounThis is not about physical height: it describes learning, tastes, or ideas that are noble, refined, or advanced. For things that are physically high or tall, it is not the word you want.
    彼かれは趣味しゅみが高尚こうしょうです。↗
    He has elegant tastes.
  • 高層こうそうJLPT N2approx.Common
    no-adjectiveConcerned with height up in the air: high altitude, the upper atmosphere, and air currents. It is not the way to say simply that something is high or tall — for that, use 高い.

Use 「高い」 for physical height and tall things, 「ハイ」 for feeling euphoric or intoxicated, 高尚 for refined or advanced quality, and 高層 for high altitude in the upper air.
