What is Hiragana?
Hiragana is one of the two Japanese syllabaries. Each character represents a sound (mora), not a meaning. It is used for native words, grammatical particles, verb/adjective endings (okurigana), and to show pronunciation above kanji (furigana). It developed from cursive forms of kanji.

What are English Syllables?
A syllable is a unit of pronunciation in English — it’s the beat you hear when you say a word.
Here are a few quick examples: cat = 1 syllable ba-by = 2 syllables beau-ti-ful = 3 syllables
On this site, English Syllables show how a name naturally breaks into sounds when spoken in English. This helps you understand how English speakers naturally say the name and where they pause between sounds.
What are Japanese Morae?
A mora (plural: morae, Japanese: 拍 Haku) is the basic unit of sound in Japanese — think of it as one rhythmic “beat” when speaking.
Here are a few quick examples: あ (a) = 1 mora あい (a-i) = 2 morae きょう (kyo-u) = 2 morae
On this site, Japanese Morae show how many “beats” a name has in Japanese. Most Japanese names have about 2–4 morae, which affects how natural and rhythmic the name sounds to native speakers.
This helps you see how the name fits into the natural rhythm of Japanese speech.

“English transcription” (romanization) is the romanized form of a Japanese name, intended to reproduce its pronunciation as closely as possible. It is also useful for searching names on this site.
Japanese-Style Nicknames
In Japan, nicknames are used to express familiarity and affection. Typical features include:
Shortened forms: Names are often shortened for closeness, e.g., “Yuki” from “Yukiko” or “Taka” from “Takashi”.
Suffixes: Terms like “-chan” (often for girls, also for young children) and “-kun” (often for boys) are used among family and close friends. Among very close adults, “-chan” may still be used. More details
Use & context: Nicknames are informal—common among friends, family, or close colleagues—and are not suitable for formal or professional settings. Their use implies a certain degree of intimacy.
Long vowels: The long vowel mark “chōonpu” (ー) extends the preceding vowel. For example, “あーちゃん” (A-chan) lengthens the “あ” sound.
