There are many katakana words in Japanese, and the number keeps increasing. Recently, we often see people calling occupations in katakana. Especially for professions that have recently appeared, there are many katakana names: such as 「purogurama̋ (programmer) - someone who writes computer programs, or 「neirisuto」 (nail artist) - someone who paints and decorates nails.
In addition, there are also professions that have existed since ancient times but have only recently been called by the word katakana. For example, calling a dance teacher 「insutorakuta̋ (instructor), calling an artist 「a̋tisuto」 (artist), calling an athlete 「asuri̋to」 (athlete). Everything is the same, saying it in katakana sounds more special and new than the old way of calling it.
When introducing myself, if I say my profession in katakana, it sounds like I'm doing a pretty good, pleasant job. ② Something like this is probably also the reason why more and more people call their profession in katakana.
