What does omedetou mean in Japanese?
The word Omedetou (お目出度う) literally means congratulations on some auspicious occasion such as a birthday, wedding, or promotion. The word is composed of the adjective medetai (目出度い) which means happy, auspicious, cheerful, and favorable.
The word is composed of the ideograms eye [目] exit [出] and occurrence [度]. This word is usually accompanied by the famous expression gozaimasu (ございます) which makes the expression a bit more formal.
Ironically, the adjective medetai can also mean naive, innocent, foolish, good-humored. There are Japanese sweets that are also called omedetou (御目出糖) and are made from glutinous rice and azuki beans.
Other strange ways of writing “Medetai” that have fallen out of use are [芽出度い] and [愛でたい]. Nowadays, the word is more often written in hiragana when it is a congratulatory expression (omedetou) and sometimes with kanji if used as an adjective.
