Each modern prefecture has a unique flag, most often a bicolour geometric highly stylised design (mon), often incorporating the letters of Japanese writing system and resembling company logos. A distinct feature of these flags is that they use a palette of colours not usually found in flags, including orange, purple, aquamarine and brown.
Some prefectures also have alternative official flags called "symbol flags" (シンボル旗). They may be used on less formal occasions. Famous symbol flags include the one used in Tokyo.
