The Asian mainland influence on Japanese culture refers to the influence of the Asian mainland on Japanese culture.
Science
During the reign of the Japanese Emperor Kinmei, a Korean physician and several kinds of medicines were sent from Baekje to Japan to help avert the dread disease. Baekje buddhist priest and physician Gwalleuk came in the reign of the Japanese Empress Suiko, and brought books on astronomy, geography and calendrical science, which led to use of the calendar in Japan, whereupon students were chosen to be educated in these sciences. He also taught medicine to the young students selected by the Japanese imperial court.
Music
In the field of Korean and Japanese music history, it is well known that ancient Korea influenced ancient music of Japan. Since the 5th century, musicians from Korea visited Japan with their music and instruments. Komagaku, literally "music of Korea", refers to the various types of Japanese court music derived from the Three Kingdoms of Korea and northern Korean state of Balhae, later classified collectively as Komagaku. It is made up of purely instrumental music with wind- and stringed instruments(became obsolete), and music which is accompanied by mask dance. Today, Komagaku survives only as dance accompaniment and is not usually performed separately by the Japanese Imperial Household.
Instruments
As early as the 5th century the Kudaragoto, which resembles the western harp, had been introduced from Baekje to Japan along with Korean music. It has twenty three strings, and was designed to be played in an upright position. And the 12-string long zither Shiragigoto was introduced as early as 5th or 6th century from Silla to Japan. However, today, the two instruments has fallen out of use by traditional music performers.
Some instruments in traditional Japanese music originated in Korea: Komabue is a six-hole traverse flute of Korean origin. It is used to perform Komagaku and Azuma asobi(chants and dances, accompanied by an ensemble pieces). San-no-tsuzumi is an hourglass-shaped drum of Korean origin. The drum has two heads, which are struck using a single stick. It is played only in Komagaku.
Imperial family
According to the Shoku Nihongi (続日本紀), Takano no Niigasa, background of the naturalized clansmen Yamato-no-Fumito (和史), was a 10th-generation descendant of King Muryeong of Baekje who was chosen as a concubine for Emperor Kōnin and subsequently became the mother of Emperor Kanmu. It has been theorized that the Japanese imperial line has Korean ancestry. As reported in National Geographic, Walter Edwards, professor of Japanese studies at Tenri University in Nara, states that "Blood links between Korea and the Japanese imperial family are documented from the eighth century. Even the current emperor has said that he has Korean ancestry." Since 1976, foreign archaeologists have been requesting access to the Gosashi tomb which is supposed to be the resting place of Emperor Jingu, but these requests have been denied. In 2008, Japan gave foreign archaeologists limited access to the site, but without allowing any excavation. As National Geographic wrote, Japan "has kept access to the tombs restricted, prompting rumors that officials fear excavation would reveal bloodline links between the "pure" imperial family and Korea"
