Common Kanji Variants and Exact Meaning
健二 (Kenji) — Health and Second Son
The most widespread kanji for Kenji is 健二, combining 健 (ken, meaning healthy or strong) and 二 (ji, meaning two or second). This composition is generally interpreted as "healthy second son" or "second son who is strong." Parents may choose this kanji to express hopes that a younger son will grow in good health. Because 健 commonly appears in names related to health, Kenji often carries positive, protective wishes for the child.
Other Kanji Options and Nuances
Japanese given names can use different kanji with similar sounds but distinct meanings. Less common variants include:
- 剣二 (kenji) — "sword, second"
- 賢二 (kenji) — "wise/clever, second"
- 乾二 (kenji) — "dry, second" (rare in practice)
Speakers and readers usually interpret the name as 健二 unless context or spelling indicates otherwise. The everyday understanding centers on health, steadiness, and family position.
On'yomi and Kun'yomi Readings
On'yomi (Chinese-derived Reading)
The on'yomi for 健 is ken, and for 二 is ji. In the name Kenji, these combine as Ken-ji. On'yomi readings are used in Sino-Japanese compounds and in many given names, producing a clear, balanced pronunciation.
Kun'yomi (Native Japanese Reading)
Names seldom rely on kun'yomi, but 健 can occasionally be read as tam(eru) or sumi, and 二 as futa. In practice, the given name Kenji is nearly always pronounced as the on'yomi ken ji, making it easy to read and remember.
