Tosa school
Mitsuoki reinstated the Tosa school style by incorporating the space and light touch somewhat similar to the earlier Song dynasty and Yuan dynasty (AD 960–1279) Chinese court paintings. He also put greater stress on ink brushwork. Mitsuoki had a style that was decorative, refined, and precise all at the same time, and throughout his career he maintained a consistent delivery. The birds and the landscapes were soft and delicate lines formed some inspiring pieces filled with beauty. His light-hearted linework, originality of design, and excellent execution, Mitsuoki combined tones which were bright without hardness, sometimes with touches of gold forming a harmony of color that was hard to find in his era. He became one of the most renowned Japanese exponents of bird-and-flower (kachō) painting in the Chinese court manner and is especially noted in his precise depictions of quail. His flower pieces were elegant, and given some tender sediment. Mitsuoki's sternness of his older style, never lost its dignity, but gained gentleness and tranquility. The Emperor, nobles and rich families collected and preserved his books.
