hello, because you didn't send the picture, I don't know what you mean by a circle. I'll tell you what I know below, which should be helpful to you. I hope you can adopt it, thank you!

Japan's currency issuing bank is Japan's central bank-Bank of Japan. The issuance of Japanese currency first began in the 8th century. In the 17th century (16), Japan established its own market system, and in 16, it began to circulate the early Japanese banknotes. May 1th, 1871 is the birth date of the Japanese yen. On this day, Japan legally established a monetary system based on gold, and at the same time promulgated the "New Currency Regulations", which said: "The name of new coins takes the circle as its origin."

Before the establishment of the Bank of Japan, Japanese paper money used to include government paper money and national bank notes. The Bank of Japan was established in 1882 and opened on October 1th of the same year. On May 9, 1885, the Bank of Japan issued the first Japanese bank note, which is a silver exchange note with 1 silver dollar as the monetary unit. In 1899, Japanese banknotes were unified into Japanese bank notes, and the original government banknotes and national bank notes ceased to be used.

At present, the paper money in circulation is mainly 1, 5 and 1 yen in 1993 and 2 yen in 2. There are also a small number of 1, 5 and 1 won banknotes issued by the Bank of Japan on November 1, 1984.

face features: Japanese bank notes are all written in Chinese characters (arranged from left to right), and the words "Japanese bank notes" are printed on the top. On the back, there are the words "NIPPON CINKO" (Bank of Japan) and "YEN" (Yuan) in Latin pinyin. All kinds of banknotes have no date of issue, and the person in charge of the issuing unit uses a seal, that is, the face is printed with a red "seal of the president" and a "stamp of the issuing director". For the convenience of the blind, there are signs in Braille. Bank of Japan logo.

1, yen: The portrait on the 1, yen banknote is Fukuzawa Yukichi, a great educator and thinker in Edo and Meiji era. Fukuzawa Yukichi was born in Osaka in 1835. After studying Lanxue in Nagasaki (western science introduced to Japan through the Netherlands after the mid-Edo period), he opened the Lanxue School in Edo, which is the predecessor of Keio University. Fukuzawa Yukichi also accompanied the shogunate envoys to Europe and America for three times, which greatly broadened their horizons. "Encouraging Learning" is one of his famous books, which preaches the importance of human equality and knowledge. Just as one of his famous sayings: "God does not create people from above, nor does he create people from below", it means that people are born equal, and there is no difference in birth, family and occupation, so people should not be treated separately. Treasure pattern: This is an imaginary pattern. This auspicious flower is painted on the royal collection of Zhengcangyuan. Various patterns are painted on the face of paper money, which not only endows paper money with an elegant character, but also plays an anti-counterfeiting role.

The portrait on the 1,-yen note is said to be Fukuzawa Yukichi's favorite photo at the age of 56, which is still kept in the Fukuzawa Research Center of Keio University.

The pattern on the back of the 1, yen note is a pair of pheasants. Pheasant is the national bird of Japan, inhabiting Honshu, Shikoku and Kyushu. The male pheasant has a loud cry and is about 8cm long, slightly larger than the female pheasant. The pheasant pattern on the 1,-yuan Japanese currency was drawn based on the sketches of the printing bureau's craft museum in Ueno Park and the cactus park of Kanagawa Makoto. Because the pheasant drawn from the sketch was kept in the zoo, the suggestion of the Mountain Terrace Bird Research Institute was finally adopted, and finally it was changed into a wild gesture as a pattern.

5, yen: The portrait of the 5, yen banknote is Nitobe Inazo, an educator and international celebrity who was very active from Meiji period to the early Showa period. Nitobe Inazo once served as the president of No.1 Senior High School, the first president of Tokyo Women's University and the president of Tokyo College of Women's Economics (now Tokyo Cultural Academy), and made great contributions to education, especially women's education, from Meiji to Taisho. He also served as the Deputy Secretary-General of the United Nations and the head of the International Committee on Knowledge Collaboration, and played a great role in the international community. Even under the tense international situation of Japanese withdrawal from the United Nations and the imminent outbreak of the First World War, Nitobe Inazo, as a true liberal, has contributed to the promotion of world peace.

The portrait used on the 5,-yuan Japanese currency was taken by Nitobe Inazo when he was a professor at the University of Tokyo at the age of 55. It was taken with his American wife Merry at the wedding of his adopted daughter. Wearing a white tie of blessing.

a map of the world is drawn on the lower left of the paper money. This is a sentence from Nitobe Inazo, the peace envoy of Japan during the war: "I would like to cross the Pacific Ocean as a bridge", so there is neither Japan nor the United States in the middle of the map, but the Pacific Ocean.

on the back of the 5, yen note, there are pictures of Mount Fuji and Benqi Lake. Mount Fuji is located in the middle of the Japanese archipelago, with an altitude of 3776 meters, which is the highest mountain in Japan. Located in the Fuji volcanic belt, it is a typical cone-shaped dormant volcano, and its biggest feature is that the beautiful Yuan Ye stretches at the foot of Mount Fuji. The lake in front of us is "Benqi Lake", which is one of the "Five Fuji Lakes" around Mount Fuji, located in the west. The flowing water of Mount Fuji pours into Benqi Lake, and the clear lake reflects the beautiful Mount Fuji. People call this reflection "inverted Fuji" and it is often painted and photographed. Mount Fuji on the 5,-yen note is a vision shot by photographer Mr. Okada Hongye standing on the mountain near the lake in 1936.

2 yen: 2 yen new banknotes came into use on July 19th, 2. Printing and issuing new banknotes of 2 yuan was originally proposed by Obuchi when he was alive. The reason was that the Japanese economy was recovering from a decade of decline in the Millennium, and issuing new banknotes would stimulate consumption. The reform of banknotes in 1984 brought about the growth of vending machines and financial machines by more than 1%. What is worth looking forward to is its spread effect on the economy.

The front design of the new p>2-yen banknote is the ceremonial gate in Ryukyu Mura, Okinawa Prefecture, and the back is the scene of the meeting between Hiroshi and Lengquanyuan in the Tale of Genji, a Japanese national treasure.

This is the first time that Japanese pseudonyms have been used on paper money.

1, yen: The portrait of the 1, yen banknote is Natsume Soseki, a great writer in Meiji period. Shu Shi worked as a teacher after graduating from the English Department of Imperial University of Tokyo (now Tokyo University). He was sent to England by the Ministry of Education for English studies and lived in England for about 2 years. After returning to China, influenced by Takahama Xuzi and others, Shu Shi published many works, such as I am a cat and Young Master, which described the experience of the teacher's time, and were deeply loved by the general public. Many famous works, such as Heart, published in his later years, are even more famous in the world. So it was adopted as a portrait of paper money. The portrait used on the 1,-yen banknote is based on the photo of Shu Shi at the age of 45 in the first year of Taisho (1912). Serial number: Today's 1, yen banknotes are printed in brown. It was originally released in black, and it was changed to blue when it was released on November 1, 199, Heisei 2. This is because 1 yen banknotes are used up because of their large circulation and high consumption. When it was issued on December 1, 25 (1993), it was changed to brown like the 5 and 1 yen banknotes.

A pair of male and female red-crowned cranes are painted on the back of the 1,-yen coin. The image of the red-crowned crane on the 1,-yen coin is based on the photos taken by the photographer and ecological researcher of red-crowned crane, Mr. Yokota, showing the heroic courtship and dancing of the red-crowned crane.
