ハイボール

はいぼーる
noun
highball; whisky and soda
food
1. highball; whisky and soda
A cocktail of whisky diluted with soda water and served over ice, typically in a tall glass. In Japan, it became a major casual drink in the 2000s and is now standard at izakaya, restaurants, and convenience stores.
ハイボール一杯(いっぱい)(くだ)さい。
One highball, please.
Highballs go well with fried food.
The canned highballs sold at convenience stores can be enjoyed casually at home, too.

From English "highball." In Japan the term refers almost exclusively to whisky-and-soda; the broader English meaning of "any spirit served tall with a mixer" is rarely intended.

Cultural note

Highballs declined in popularity in the late 20th century but were revived nationally by Suntory's promotional campaign for (かく)ハイ (Kakubin highball) starting around 2008. They are now a default casual order at izakaya alongside beer and chūhai.
