句読点

Japanese punctuation marks (Yakumono) are different from Western ones. They are full-width characters.

句点(くてん)- Period

Input: "." usually converts to "。"

読点(とうてん)- Comma

Used to separate clauses. Slants to the right.

Input: "," usually converts to "、"

鍵括弧(かぎかっこ)- Quotation Marks
「」

Quotation marks. Used for speech or quoting text.

「こんにちは」と彼は言った。
中黒(なかぐろ)- Middle Dot

Middle dot. Used to list items or separate foreign names.

全角(ぜんかく)- Full-width

Characters that take up the full width of a square. Used for Japanese text, punctuation, and symbols.

Examples:
あいうえお ABCDE 12345 !?

半角(はんかく)- Half-width

Characters that take up half the width. Used for English text, numbers, and basic symbols in technical contexts.

Examples:

Note: Japanese input methods typically convert spaces, numbers, and punctuation to full-width by default.

縦書き(たてがき)- Vertical Writing

Traditionally, Japanese is written vertically from right to left.

  • Books (Novels)
  • Newspapers
  • Greeting Cards (年賀状)

Websites and modern documents usually use horizontal (横書き) left-to-right style.
