You may notice that Raito also transcribes to the English word light. It is indeed the case that, sometimes (especially among babies born from the Heisei period (1989-2019) onwards), kanji either related to the word or otherwise used for image conjuring are used, like 光 meaning “light; ray, beam, glow,” 月 meaning “moon,” 輝 meaning “brightness, brilliance” and 煌 meaning “glitter, sparkle.” While single kanji are used for this name, they are more likely to be combined with a to kanji or another kanji with some sort of connection to light, examples of the latter being 煌月, 輝星 and 月輝.

Popularity:
In use since at least the 1920s, much of its usage is concentrated on those born in the Heisei period onwards. In 1990, it was only given to around 0.005% of boys, remaining stable until the late 1990s when it began to rise in usage. By the late 2000s, well over 0.12% of boys received this name.
Based on my 2014-20 names research, by 2014, it already ranked in the top 100 with 0.253% of boys receiving this name and peaking at 0.332% and ranking 74th in 2015.
