The bureaucratic administration of Japan is split into three fundamental ranges; nationwide, prefectural and municipal. Under the nationwide degree are 47 elements, or prefectures, and the minimalist symbolism within the prefectural flags is interesting, with most designs incorporating extremely stylised letters from the Japanese writing system.
Flag of Fukuoka. Stylised hiragana of ふく (fuku). Additionally represents ume (plum), the prefectural flower.
Flag of Gifu. Stylised kanji 岐 (gi). The logo expresses peace and concord. Inexperienced for the character of Gifu.
Flag of Ibaraki. The prefectural flower rose on blue area. Blue for the Pacific Ocean and Mount Tsukuba.
Flag of Kagawa. Stylised and barely rotated katakana of カ (ka). Additionally represents mountains, and leaves of the olive, the prefectural tree.
Flag of Kyoto. Stylized kanji of 京 (kyō).
Flag of Miyagi. Stylised hiragana of み (mi). Additionally represents the miyaginohagi (lespedeza), the prefectural flower.
Flag of Tottori. The image represents the hiragana と (to) and a chicken (tori) to kind a rebus of Tottori.
All prefectural flags are on Wikipedia.
Under the extent of prefectures are the municipalities. Additionally they have flags with properly thought-about symbolism and, for probably the most half, applicable restraint.
