The list of Japanese municipal flags lists the flags of municipalities of Japan. Most municipalities of Japan have unique flags. Like prefectural flags, most of them are with a bicolor geometric highly stylized symbol (mon), often incorporating characters from Japanese writing system (kanji, hiragana, katakana, or rōmaji). However, there are three types of symbols (emblems, logos and crests). Therefore, the list will also discuss the emblems or logos.
