この旗は万国津梁旗と言い、首里城正殿の万国津梁の鐘の銘文に基いてデザインされた。
この旗の上下に二筋の紺碧の帯がある。これを上顎と下顎と見て、すなわち大明を輔車（頬骨と歯茎の関係）としている。中央に日本を示す日の丸があって、これが沖縄を表す守礼之門と重なり、まさに日域、つまり日本をもって唇歯となしている。この場合、沖縄が日本からはみ出しているのは、沖縄人は出っ歯か？と余計なチャチャを入れないで貰いたい。これはニッコリ微笑っているので歯も唇も両方見えているのだ。三韓の秀は、さてこれが難しい。この旗の色を見ると、地の色の白をこれを無地とみなして、青、赤、緑、三色である。この三色で馬韓、弁韓、辰韓、古代朝鮮の三韓をあらわす。南海の勝地は、中央の日の丸へ戻ってこれを特に日本の象徴と見ず、むしろ南国の太陽と見れば、これ南海の勝地なり。舟楫をもって万国の津梁となすさまは、大明の時に使った上下二筋の線をもう一度見る。これが紺碧であるのを舟の航跡と見る。この航跡が旗の右の端から左の端まで、まさに架け橋として繋いでいる。異産至宝が十方刹に充満しているさまは、沖縄を表す守礼之門が緑で埋め尽くされていることで示される。後ないのは蓬莱島ぐらいだが、これは扁額に「守禮之邦」とあるのが蓬莱の異名である。（以下略）このように沖縄独立旗の全てが、万国津梁の銘文を体現しているので、これを万国津梁旗とも呼ぶ。
This is the national flag of Okinawa which is called "the Flag of the International Bridge" and the design is based on the inscription on the Bell of the International Bridge at the Main Building of the Syuri Palace.
The inscription on the Bell of the International Bridge (also the national anthem of Okinawa) is:
The Ryukyu Kingdom:
is the strategic point on the south sea;
calls excellences among the three kingdoms of Korea;
relates the Great China cheekbones and the gums;
relates the Japanese Area lips and tooth;
is emerging paradise islands locates between these two;
makes a ship the international bridge;
is filled with the rarest and the greatest treasure;
the land is little hot, people fan Confucian virtue of Japan and China.
....
The flag has two deep-blue strips on the top and the bottom. Regarding them as the upper and the lower jaws, they symbolize relationship between the Okinawa and the China (cheekbones and the gums).
There is Hinomaru (the rising sun) in the center overlapping with the gate of the right conduct symbolizing Okinawa. That is the relationship between Okinawa and Japan (lips and tooth). In this regard, you do not make fun of Okinawa sticking out of Japan if it means Okinawa is bucktoothed. She is smiling that why both lips and tooth are both seen.
Excellences among the three kingdoms of Korea is, well this is difficult. Notice the colors of the flag and ignore the white background as colorless, there are three colors. Blue, red and green. They represent three kingdoms in the ancient Korea.
The strategic point on the south sea is, back to the central Hinomaru, codified by the sun. Consider this the sun in the south rather than the symbol of Japan.
Making a ship the international bridge is, see the two strips which is also used for the China. They are deep-blue, apparently for the wakes behind a ship. A wake reaches form side to side certainly connecting both sides as a bridge.
The kingdom filled with the rarest and the greatest treasure is shown by the gate of the right conduct symbolizing Okinawa filled by green.
Still missing is the paradise islands. The words on the tablet of the gate of the right conduct, "the nation of the right conduct" is an another name for the paradise.
(The rest is omitted.)
Such being the case, everything on the flag embodies the maxim of "the international bridge" and the flag is called the Flag of the International Bridge.
