Born into the Urabe clan, his real name was Urabe Kaneyoshi. After serving Emperor Go-Nijo, he took Buddhist vows and became known as Kenko Hoshi. Around 1330, he wrote "Tsurezuregusa" (Essays in Idleness), a 243-section essay spanning life, nature, impermanence, and worldly wisdom. With keen observation and a witty, elegant style, he depicted human folly and the transience of the world. His erudite writing, grounded in Japanese and Chinese learning, profoundly influenced later generations.
