was the pen-name of a Japanese literary critic, active in Taishà  period Japan. His real name was Kuriyagawa Tatsuo.
Kuriyagawa Hakuson was born in Kyoto. He graduated from Tokyo Imperial University, where he had studied under Koizumi Yakumo and Natsume SÃ Âseki, and later became a professor at Kumamoto University and Kyoto Imperial University. He lectured on 19th century Western literature, and criticized traditional Japanese writing on naturalism and romanticism. His writings include: Kindai bungaku jikko ("Ten Aspects of Modern Literature", 1912), Zoge no to o dete ("Leave the Ivory Tower!", 1920) and Kindai no ren-aikan ("Modern Views on Love", 1922).
In Kindai no ren-aikan Hakuson regarded "love marriage" (renai kekkon) to be a practice indicating an advanced nation and society, as opposed to the practice of arranged marriage, which was more commonly practiced in Japan at the time.
He was killed by a tsunami, which swept away his cottage near the beach in Kamakura, Kanagawa prefecture, during the Great Kantà  earthquake of 1923.
