Yōshin-ryū (楊心流^?) ("The School of the Willow Heart") is a common name for one of several different martial traditions founded in Japan in the Edo Period. The most popular and well-known was the Yōshin-ryū line founded by physician Akiyama Shirōbei Yoshitoki in Nagasaki in 1632. The Akiyama line of Yōshin-ryū is perhaps the most influential school of jūjutsu to exist in Japan. By the late Edo Period, Akiyama Yōshin-ryū and its descendants had spread all over Japan. By the Meiji Era, Yōshin-ryū had even spread overseas to Europe and North America.

This line of Yōshin-ryū is noted for a curriculum including kyūsho-jutsu atemi (vital points striking) and the development of internal energy, teachings most likely influenced by Chinese sources. It is believed that these teachings were eventually absorbed by many other jujutsu traditions.

Only the Yōshin-ryū buki/naginata school in Hiroshima, Japan currently headed by Koyama Takako and attributed to Akiyama has been successfully transmitted and survives. The school was prolific, however, with its teachings surviving in many descendant ryū.

Schools descended from Akiyama Yōshin-ryū jūjutsu include:

Danzan ryu, Shin Yōshin ryū, Shin Shin ryū, Sakkatsu Yōshin ryū, Shin no Shindō ryū, Tenjin Shin'yō-ryū, Shindō Yōshin-ryū, Takamura ha Shindō Yōshin ryū, Wadō-ryū (a modern Jūjutsu Kenpo/Karate school based on Shindō Yōshin-ryū), Ryushin Katchu ryū, Ito ha Shin'yō ryū, Kurama Yōshin ryū, Kodokan Judo.
