How to Say ‘Is the water heater powered on?’ in Japanese
給湯器の電源は入ってる？
kyuutou ki no dengen wa haitsu teru
[kyuu-toh kee noh den-gen wa haht-teh teh-roo]
💬 Usage Tip: [入ってる？] is the casual spoken form of [入っていますか？]. For power and switches, Japanese says [電源が入る] — literally "the power enters," but naturally "the power is on."
🇯🇵 In Japan: This sounds casual and natural between people who know each other, like a landlord speaking informally. In a more formal interaction, you'd expect [入っていますか？].
