What is Hiragana?

cat = 1 syllable

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.

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.
