Japanese Names That Start with K
Boys, girls, and gender-neutral K names with meanings and kanji
Japanese names that start with K come from one of the largest starting-sound groups in Japanese, because the kana row ka-ki-ku-ke-ko turns five sounds into K names. This page is the cross-gender hub for japanese names starting with k: the girl and boy lists below each open pre-filtered on K, and a dedicated section covers gender-neutral picks such as Kaede. If you already know you want a girl name, the Japanese girl names starting with K page keeps that intent; use this hub to compare both genders, check kanji, and shortlist faster.

Girl Names That Start with K
The girl list gathers Japanese names that start with K that Japanese parents actually register for daughters. Kaori, Kanna, Kana, Kotone, and Kasumi are steady favorites, with kanji leaning toward fragrance, flowers, music, and gentle weather imagery. The browser below opens directly on K, so you can compare sound, kanji, and meaning inside the exact letter set you searched instead of scrolling the whole girl database.

Boy Names That Start with K
The boy list collects Japanese names that start with K whose sound is firmer and more outward-facing: Kaito, Kenji, Kenta, Kazuki, and Kōta are long-established picks, typically built on kanji for ocean, health, victory, and brightness. Remember that ka-ki-ku-ke-ko all count as K names, so Kaito (ka) and Kōki (ko) belong on the same list even though their vowels differ. The browser below opens on K with meanings and readings side by side.

Gender-Neutral K Names
Gender neutrality in Japanese names comes from kanji and reading habits, not from the first letter. Kaede (楓, maple) is the clearest example among japanese names beginning with k: it was long used for girls, and naming communities now report it ranking inside the boys top 100 as well, with the same kanji serving both genders. Kai (海, ocean) reads masculine-leaning in Japan but unisex to international ears. Kazumi and Katsumi flip the logic: the readings are unisex, while the kanji decides the lean — 美 (beauty) pulls feminine, 勝 (victory) pulls masculine. Kohaku (琥珀, amber) moves between genders depending on the pair. When neutrality matters, pick the reading first, then choose kanji that match the tone you want on paper.
K Name Meanings and Kanji
A handful of kanji generate most Japanese names that start with K: 海 (ocean) powers Kai and Kaito, 楓 (maple) is Kaede, 勝 (victory) builds Katsuo and Katsumi, 健 (healthy) builds Kenji and Kenta, 琴 (koto harp) builds Kotone, and 光輝-style brightness kanji build Kōki. Two checks keep a K name safe. First, same sound, different name: Kōta can be written 晃太, 康太, or 浩太, so confirm the exact pairing before you commit, because the meaning changes with it. Second, long vowels survive registration but not always romaji: Kōta and Kota collapse to the same English spelling, so decide how you want the name to read abroad and record the hiragana precisely. Say the full name with a surname, then check whether the kanji still looks like a person and not a word.
