Hello, I’m Kodak.
最高 (saikō) is one of the most useful Japanese words for enthusiastic praise.
Its literal meaning is “the highest”, but in everyday conversation it often means “the best,” “amazing,” “awesome,” or “it couldn’t be better.”
① the highest
The highest position, level, score, temperature, or amount
② the best
The best person, thing, experience, or result within a comparison
③ awesome / amazing
An enthusiastic reaction meaning “This is fantastic!”
Today’s Japanese word is 最高 (saikō)!
It combines 最 (sai: most) and 高 (kō: high).
Its core image is “reaching the highest possible level.”
From that image, 最高！ naturally became a way to say “The best!” “Awesome!” or “It doesn’t get better than this!”

↓

How to Pronounce and Write 最高
Hiragana: さいこう
Katakana: サイコウ
Romaji: saikō / saikou
Mora: さ・い・こ・う (4 morae)
The final こう (kō) contains a long vowel. In careful romanization, this may be written with a macron as saikō. In typing and search queries, saikou is also common.
さ・い・こ・う
sa – i – ko – o
Important:
Do not shorten the final long vowel so much that さいこう sounds like a three-mora word.
How to Use 最高 in Japanese
