Meaning

Declining; setting sun; waning. Used to describe industries, organisations, or eras in decline.

Literally 'the slanting sun,' this word gained its metaphorical meaning of decline largely through Osamu Dazai's influential 1947 novel 斜陽, which depicted the downfall of Japan's post-war aristocracy. Now commonly applied to industries, companies, or social structures that are past their peak. 斜陽産業 is a set phrase meaning 'sunset industry.'
