The Japan Maritime Self-Defense Force ( JMSDF ) had just unveiled the ship emblem of its fourth Mogami-class multi-mission stealth frigate the JS Mikuma ( FFM-4 ). It was the result of a design competition which was open to the public from 6th Jun to 5th Jul 2022. Out of a total of 157 submissions, the winning piece was selected by the pre-commissioning ship crew themselves and it featured a mythical hawk known as the Hitaka, the sun, the moon, a star ( Polaris ) and the Big Dipper.
Apart from Polaris and the Big Dipper, all the above entities are key characters in the Legend of the Sun and Hawk ( 日と鷹神話 ) recorded in the ancient text known as Toyonishi Manuscript ( 豊西記 ). It is the story of the creation of the Mikuma river and the three hills around it.
In Japanese, the ship's crest or emblem is known as the logo mark ( ロゴマーク rogo maku ). My previous articles on the JS Mogami and the JS Kumano's logo mark can be found here, JS Noshiro's here and that of the JS Ise's possibly plagiarised logo mark here.

Sun and Hawk Legend
The Mikuma River ( 三隈川 mikumagawa ), namesake of the multi-mission frigate JS Mikuma , refers to the section of the Chikugo River that flows westward through the city of Hita right in the heart of Kyushu. The Hita Basin ( 日田盆地 Hita Bonchi ) is located just north of one of Kyushu's most active volcano Mt Aso and it is surrounded by mountains. It lies within the boundaries of Oita Prefecture, an area known in the past as Bungonokuni ( 豊後国 ).
Legend had it that a long long time ago there was a gigantic lake in the Hita Basin. One day, a humongous bird known as the Sun Hawk ( 日鷹 Hitaka ) flew across the lake from the east, dipped the feathers of its wings into the water and then flew north as the sun rises and disappeared. That immediately triggered off terrifying earth tremors and suddenly turned day into night.
The huge whirlpools formed and monstrous waves battered the cliffs on the western banks of the lake for three days and three nights. The cliffs eventually collapsed and the water gushed out and formed the westward flowing Mikuma River. As a result of the outflow, the lake was completely drained. The torrent also created three knolls which are known as the Hill of the Sun ( 日隈 Hinokuma ) to the south, Hill of the Moon ( 月隈 Tsukikuma ) to the north and the Hill of the Star (星隈 Hoshikuma ) to the west.
Collectively these hills are known as the Three Hills of Mikuma ( 三隈三山 Mikuma Sanzan ) or the Three Knolls of Hita ( 日田三丘 Hita Mitsuo ). These geological features still define the terrain where the Mikuma river flows through today.

Could this ancient foklore have a possible scientific explanation? Absolutely! Japan has numerous active and dormant volcanos and many of these have caldera lakes. The rims of these crater lakes are subjected to weathering and erosion and can obviously be destroyed by subsequent seismic activities or even an eruption. Mt Aso, located just south of Hita City, has a caldera with a circumference of 120km, one of the biggest in the world, and that could have once been filled with water. Satellite imagery even showed a breach over its western rim from which a river flowed.

JS Mikuma's Logo Mark
The ship's crest of the JS Mikama takes a pentagonal shape with the silhouette of the mythical Sun Hawk in black prominantly featured at its centre. Its wings are spread and stretched right across the entire crest with the wingtips extending a little beyond the geometry of the crest. Superimposed on the hawk are the silhouettes of water in light blue and that of the warship in grey. They signify that the JS Mikuma will have the power of the water to move forcefully forwards.
Above the hawk is the sun, which represents Hinokuma, the hill of the sun. It is positioned above all perhaps because in Shintoism the Sun Goddess Amaterasu Okami is regarded as the supreme deity.
The moon at the lower left represents the Tsukikuma, the hill of the moon. According to JMSDF, the star at the lower right of the crest is Polaris ( 北極星 Hokkyokusei ), the north star. It represents the Hoshikuma, the hill of the star. Next to it is the asterism known as the Big Dipper ( 北斗七星 Hokutoshichisei ) with its seven stars in its familiar inverted ladle configuration. Interestingly, these stars are orientated in the correct position as they would in the night sky, with the two stars of the Big Dipper's bowl pointing towards Polaris. Kudos to the designer for getting this right! Together, Polaris and the Big Dipper would herald safe navigation on the high seas.
The crest is framed by a perimeter of dark grey within which the words Japan Maritime Self-Defense Force is written at the top and FFM-4 JS Mikuma is written at the bottom. Lastly, the words みくま, the ship's name in hiragana, is placed in front of the silhouettes of the hawk, water and warship.
JS Mikuma's ship crest was designed by Sasaki Ruri ( 佐々木留理 ) from Nara Prefecture.

Note : The Japanese kanji character 三 ( mi ) means three while 隈 ( kuma ) means corner or nook. In combination 三隈 ( Mikuma ) literally means three corners or three nooks. However, in this case we know that it means the three hills of Hita.
