Kotetsu is Japanese in Origin.

Kotetsu is a Japanese masculine given name, variously written as 虎徹, 小鉄, or 古鉄, combining elements such as ko (“tiger,” 虎, or “small,” 小) and tetsu (“thorough/penetrating,” 徹, or “iron,” 鉄). Depending on the kanji, meanings range from “tiger of resolve” to “little iron,” evoking strength, resilience, and precision. As with many Japanese names, nuance shifts with the characters chosen; some modern forms use alternative ko kanji like 琥 (“amber”) for a softer tone while retaining a strong tetsu core.

The name is attested since the Edo period via the renowned swordsmith who signed Kotetsu (虎徹), giving it a martial cachet; it later appears among athletes, entertainers, and in pop culture, keeping it recognizable though uncommon. Variants and related forms include the romanizations Koutetsu and Kōtetsu; short forms Ko and Tetsu; and cognate names on tetsu, such as Tetsu, Tetsuya, and Tetsurō. Predominantly masculine in Japan; rare elsewhere but accessible in English.
