How to say "brightly" in Japanese

Choosing the right word
  • adverb (with と)For the flashing, dazzling sense of 'brightly' — a sudden gleam or sparkle rather than steady light. A less common mimetic word, it suits something flashing brightly for an instant as it catches the light.
  • 冴え冴えさえざえ
    adverb (with と), suru verbCovers brightness as clarity and vividness — light or color that is crisp, fresh and clear rather than intense. A less common word, it suits colors or a scene that look bright and sharply defined.
  • adverb, suru verbAlso covers the flashing, dazzling, sparkling sense of 'brightly'. This less common mimetic word depicts a sudden, momentary flash — light that gleams brightly for an instant rather than shining steadily.
  • adverbA common word, usually written in kana alone. It conveys 'brightly' as light reaching everywhere, leaving no dark corners — hence also 'clearly'. It is not the word for flashing or dazzling brightness.

For flashing, dazzling or sparkling light use 「ぴかり」 or 「ピカッと」; 「冴え冴え」 suits clear, vivid brightness; 「くまなく」 describes light that reaches everywhere, leaving no dark corners.
