How to say "boy" in Japanese

Choosing the right word
  • 君くんJLPT N4approx.Common
    suffixNot the plain word for a male child: it is a way of addressing a boy, corresponding to the 'Mr' and 'master' senses, and is seldom what you want for 'boy' itself.
    トニー君くんはなんと上手じょうずにテニスをすることができるのだろう。↗
    How well Tony can play tennis!
  • 少年しょうねんJLPT N3approx.Common
    nounA boy as a young male, typically one not yet grown; it tends to appear in writing, news reports and official contexts, and can sound more formal than 男の子.
    少年しょうねんは木きに自分じぶんの名前なまえを刻きざんだ。↗
    The boy carved his name on the tree.
  • 男子だんしJLPT N3approx.Common
    nounA boy viewed in contrast to girls; it fits contexts where males and females are distinguished or grouped, such as school and sports settings.
    このクラスは女子じょしが男子だんしより多おおいです。↗
    There are more girls than boys in this class.
  • 男の子おとこのこJLPT N5approx.Common
    expression, nounThe everyday word for a male child, at home in ordinary conversation; it also covers the 'son' and 'baby boy' senses, which none of the other words here share.
    あのハンサムな男の子おとこのこを見みて。↗
    Look at that good-looking boy.
  • ボーイJLPT N3approx.Common
    nounSeldom the word you want for a male child: as a loanword it usually refers to men in service jobs, such as a waiter or bellboy, so turn to 男の子 or 少年 instead.

For 'boy' in everyday speech use 「男の子」, which also covers 'son' and 'baby boy'; 少年 for a youth in writing or formal contexts, 男子 when contrasting boys with girls, 君 when addressing a boy, and 「ボーイ」 hardly ever.
