Translation guide
The number four in Japanese is most commonly expressed as 四 (し/よん). The choice between し and よん depends on context, with よん being more common in counting and everyday use due to し being a homophone for 'death'. This guide covers counting, age, time, and other uses.

The reading し for 四 is a homophone for 死 (death). In many contexts, よん is preferred to avoid this association. This is especially true in phone numbers, room numbers, and when counting aloud. However, し is still used in fixed compounds like 四月 (April) and in some idiomatic expressions.
When counting objects, use the appropriate counter word. The generic counter つ (四つ = よっつ) works for many items, but specific counters exist for people (四人 = よにん), flat objects (四枚 = よんまい), etc. Always learn the counter with the number.
It's four o'clock.
