Tsuyoshi is a masculine Japanese given name.

Written forms Tsuyoshi can be written using different kanji characters in Japanese names.

The most common kanjis associated with "Tsuyoshi" generally implies sturdiness, determination, commitment, etc. and emphasizes more on mental strength rather than overpowering physical strength. Here are some common examples:

毅, "mentally strong, determined and committed" 剛, "sturdy, hard to break"

Much less commonly, Tsuyoshi can also be used with Kanjis that describe general strength:

豪, "outstanding/larger-than-life figure, famous elite" 力, "strength, power" 強, "strong"

Tsuyoshi can also be a combination between a kanji for "tsuyo" and another for "shi", so that the same three syllables can become a two-kanji name, preferred by some parents that find a single-kanji name too simplistic. In this case, the "Tsuyo" part still encompasses the same "mentally strong" or "sturdy" concept, but the kanji associated with the "Shi" syllable is often chosen not for its original literal meaning (with a goal to combine the two kanjis into a meaningful phrase), but just for a kanji with a positive connotation. The most common form for this "tsuyo" is 剛. Some common examples:

剛史, "sturdy/mentally strong", "history, historian, administrator" 剛志, "sturdy/mentally strong", "will" 剛士, "sturdy/mentally strong", "gentleman/samurai" 剛司, "sturdy/mentally strong", "administrator"

In modern Japanese names, this name is often written in hiragana ("つよし") or katakana ("ツヨシ"), which serves to encompass the general positive connotations of all the possible kanjis, rather than being limited to a single kanji.
