Translation guide
The English word "shine" covers several distinct meanings: emitting light, reflecting light, polishing something to make it bright, and excelling at something. Japanese uses different words for each, and the choice depends on what is shining and how.
Describing a light source that produces its own light and shines brightly.
General verb for shining brightly, often with a sense of brilliance or radiance. Used for stars, sun, jewels, and also metaphorically for people's eyes or achievements.
星が輝いている。
The stars are shining.
彼女の目が喜びで輝いていた。
Her eyes were shining with joy.
To shine, gleam, or glow. Often used for things that emit light intermittently or with a steady glow, like fireflies, stars, or polished surfaces. More about the physical emission of light.
蛍が暗闇で光っている。
The fireflies are shining in the dark.
遠くの灯台が光っていた。
The distant lighthouse was shining.
To shine (of the sun). Often used in weather contexts, like 'sunny'. Less common for general shining.
日が照っている。
The sun is shining.
Describing a surface that reflects light and appears bright or glossy.
Used for surfaces that gleam or reflect light, like polished floors, wet roads, or shiny objects.
磨いた床が光っている。
The polished floor is shining.
雨で道路が光っていた。
The road was shining from the rain.
Can also be used for reflective shine, but often implies a more brilliant or radiant reflection, like jewels or water in sunlight.
Onomatopoeic adverb/な-adjective meaning shiny, sparkling, or gleaming. Often used for clean, polished surfaces.
The act of rubbing or polishing something to make it shine.
To polish, brush, or shine something. Used for shoes, teeth, silver, etc.
Causative form of 光る, meaning to make something shine. Can be used for polishing, but 磨く is more common for the physical action.
彼は靴をピカピカに光らせた。
He made his shoes shine brightly.
To perform very well or be outstanding in a particular area.
Metaphorically shine, as in to excel or stand out. Often used in contexts like 'shine on stage' or 'shine in a competition'.
彼女はステージで輝いていた。
She was shining on stage.
彼は試合で輝きを放った。
He shone in the match.
Can also mean to stand out or be excellent, often used for talent or skill. Slightly more casual than 輝く in this sense.
To be recognized as superior, to be highly regarded. Literally 'to have one eye placed', meaning to be acknowledged as outstanding.
彼は同僚から一目置かれている。
He shines among his colleagues (is highly regarded).
Both mean 'to shine', but 輝く (kagayaku) often implies a brilliant, radiant shine, often with emotional or metaphorical connotations (e.g., eyes shining, shining on stage). 光る (hikaru) is more about physical light emission or reflection, and can be used for intermittent or steady glow. In many contexts they overlap, but 輝く is more poetic or intense.
星が輝く / 星が光る
Stars shine (both possible, 輝く is more poetic)
The English loanword シャイン (shain) is not commonly used as a verb meaning 'to shine'. It appears in some compound nouns (e.g., シャインカット) but is not a natural way to express the action of shining. Stick to native Japanese verbs.
彼女の顔は幸せで輝いていた。
Her face shone with happiness.
靴を磨かないといけない。
I need to shine my shoes.
湖が太陽の光で輝いている。
The lake is shining in the sunlight.
床がピカピカに磨かれている。
The floor is polished to a shine.
His talent has been shining since he was a child.
