Prefectural flags of Japan by The_Irish_Jet.
I recently collected all the prefectural flags of Japan for a project, and here they are below in rasterized form, alphabetically arranged.
Most are formed by stylized hiragana and katakana (and even kanji and alphabet) and shapes of prominent geographical features and symbols, which may not be obvious on first observation.
Embarrassingly, I didn’t even realise until recently that the emblem of Ibaraki (where I live) is a stylized rose bud. I have often wondered how it came to be and now I know.
I like simple, uncluttered design, like Ibaraki’s rose emblem. Besides that, my other favorites are Fukuoka, Hokkaidō, Kyōto, Nagasaki, Saga, and Shizuoka.
Aichi’s flag combines あ (a), い (i), and ち (chi) to form a design representing the overseas development of the prefecture facing the Pacific Ocean and the hopeful Rising Sun Wave Crest.
The Akita flag features a dynamically stylized katakana ア (a) from its name, representing the progress and development of the prefecture. A striking design by an anonymous creator, it vaguely resembles the Nike logo, which it precedes by more than ten years.
Akita’s flag shows the topographic contour of the prefecture–the green color representing hope and future, and the white color representing the infinitely expanding space.
Chiba’s emblem, the oldest of all prefectural emblems, is a combination of katakana チ and ハ to form the shape of nanohana, the prefectural flower. The blue background represents hope and development.
Ehime’s design features a Mikan blossom, the prefectural flower, shifted slightly to the left. The white of the petals represents modesty and vitue; the green represents peace and hope; and the yellow represents happiness. It’s a simple construction that contains no characters.
Fukui’s flag shows the prefecture name in katakana (フクイ) arranged in a circular design. The design where a young leaf grows between two leaves symbolizes the wish for the development of the prefecture.
Fukuoka’s flag design incorporates stylized rendetion of ふく (fuku) to represent the plum blossom, the prefectural flower. The emblem represents peace and development, and harmony and progress of the prefecture’s citizens.
Fukushima’s flag features a highly stylized rendering of hiragana ふ (fu) in circular shape, symbolizing harmony and solidarity of its people, and the steady development of the prefecture.
The emblem on the flag is stylized first kanji of Gifu’s name (岐). The green color scheme represents the beauty of nature in the prefecture.
In the middle of Gunma’s flag are the characters 君 and 羊 arranged horizontally to form 羣 (the old form of 群) surrounded by the prefecture’s three prominent mountains (Akagi, Haruna and Myōgi) stylized into crescent shapes to reprsent “growing Gunma”. The purple color of the flag represents the cultural prosperity of Kōzuke Province (Gunma in ancient times).
Hiroshima’s flag features a stylized katakana ヒ(hi) to form a circle, representing the harmony and unity of the citizens of the prefecture, while the overlap of the circles represents progress and development.
The seven-pointed star of the prefectural flag symbolizes the pioneering spirit of the ancestors who endured the harsh wind and snow and also represents the future of Hokkaidō.
The red of the star symbolizes the indomitable spirit of the people, the white represents brilliance and wind and snow, and the dark blue the sky and sea of the North.
Hyōgo’s prefectural flag features a stylized 兵 in the shape of a wave, symbolizing the prefecture’s position between the Sea of Japan in the north and the Seto Inland Sea in the south. The cerulean blue represents youth while the white expresses brightness and honesty.
Ibaraki’s flag, created by famed illustrator Kazumasa Nagai, shows a stylized rose bud, the prefectural flower. The swirls of the rose suggest advancement, creativity, dynamics and development.
Ishikawa literally means “stone” and “river”. The flag design shows the shape of the Noto Peninsula (where prefecture is located) jutting out to the Sea of Japan, and vaguely resembling an oblique 石川. The blue background represents the Sea of Japan and the prefecture’s land blessed by rich greenery, clean water and clear air.
The prefectural flag features a highly stylized, vertically symmetrical kanji of 岩, representing its progress to a prosperous and highly livable prefecture.
Stylized katakana カ (ka) from the prefecture’s name, based on the image of an olive leaf, symbol of peace since ancient times. It also represents blessed climate and development. The background color is olive green.
Olive is the prefectural tree and has been cultivated in the prefecture for over 100 years.
The design is a highly stylized rendition of the prefecture’s Satsuma and Ōsumi Peninsula and the part where Shibushi Bay is located is dented. The active volcano Sakurajima, symbol of the prefecture, is represented by the red circle in the middle.
Kanagawa’s flag features an almost abstract interpretation of the kanji 神 (“kami” or spirits venerated in the Shinto religion) from the prefecture’s name.
Hiragana と (to) from Kōchi’s old name Tosa and katakana コ (ko) from Kōchi are combined to create a circular design: the sword edge pointed upward symbolizes progress and the circle symbolizes peace and cooperation.
Katakana ク (ku) from the prefecture’s name is transformed into the shape of Kyūshū, one of Japan’s four main islands. The circle in the middle symbolizes Kumamoto’s position in the middle of the island.
This design takes the first kanji (京) of the prefecture’s name and stylized it into a six-pointed leaf, symbolizing the magnificence of the ancient city, and the over-all design represents the citizens’ unity and cooperation.
Like Miyagi Prefecture’s emblem, Mie’s flag features a stylized み (mi) designed to look like an upward arrow to create an image of the prefecture’s progress, and the circle represents the world-famous pearl farming in Ago Bay.

Miyazaki’s flag features its symbols: nature (green) and the sun (yellow). At the center is the stylized katakana ミ (mi) arranged to look like steps upwards, and represents the progress of the prefecture.
The katakana ナ (na) is stylized into a bird in flight inside a circle, where the shape of a mountain is reflected like on a lake. The design imagines the progress and development of the prefecture through its nature, and the citizen’ friendship and unity.
One of the only three prefectures to feature an alphabet on its flag, Nagasaki’s international outlook is represented by a stylized N transformed into a dove, symbol of peace, the light blue color suggesting the bright sea and sky.
Featuring a stylized katakana ナ (na), the outer cycle represents the nature of the great Yamato Province (Nara’s old name) , the inncer circle represents the spirit of harmony, and the horizontal axis represents the continuous progress of the prefecture.
Niigata’s emblem in its flag is formed by a stylized kanji 新 at its upper-middle part and the ガ (ga) on the left and タ (ta) on the right, in the shape of a collar representing harmony, hope and development of the prefecture.
Ōita Prefecture’s emblem is formed by three kanji 大大大 arranged in a circle, symbolizing trust, work and fraternity. The image of three people holding hands also represents peace and cooperation and the rising sun image the figures form represents the development of the prefecture.

The prefectural emblem consists of three circles. The outermost red circle represents the sea around Okinawa, the white circle inside is the alphabet “O” for Okinawa and the “circle of people” (suggesting peace and harmony), and the innermost red circle represents the prefecture’s potential for development.
Ōsaka’s emblem is said to have its roots in Toyotomi Hideyoshi’s battle standard, the Sennari gourd. The three branched O’s (from Ōsaka) represent hope, prosperity and harmony.
Stylized petals of camphor, the prefectural tree, form the design of the emblem, with the white petals symbolizing fairness and cleanliness, and the red stamens and pistils symbolizing honesty and passion. The flower-shape represents harmony and powerful development.
Saitama prefecture’s emblem is formed by 16 magatama beads of Sakimitama arranged in circle, symnbolizing the sun, development, passion and strength.

Four (read as “shi”) stylized katakana マ (ma) are arranged in a cloud-shaped circle to represent the citizens’ unity and the prefecture’s harmonious development and progress.
Shizuoka’s emblem combines the topographical features of the prefecture (the Izu peninsula, Suruga Bay, and Omaezaki peninsula) to form the shape of Mount Fuji, which lies at its border with Yamanashi.
The blue represents the endless sky and the Pacific Ocean, and the orange Mount Fuji and prefectural land represents the bright sunlight and passion and unity of its people.
