From a young age, Inayoshi Osamu harbored a love for nature and a knack for the handmade. His childhood was spent amidst the natural wonders, fishing in rivers, and catching insects in mountains. At home, he engrossed himself in assembling popular plastic models of the time. However, as he grew older, uncertainty clouded his vision for the future. Thus, leading to a period of depression and frequent job changes. A significant turning point for Inayoshi Osamu arrived at the age of 22 with the passing of his beloved grandfather. In Japan, it is customary to place the remains of the deceased in a ceramic urn known as "kotsutsubo." Disturbed by the undertaker's choice of a mass-produced urn for his grandfather, he vowed to craft personalized kotsutsubo for his parents, undoubtedly instilling a newfound purpose in his life. Thus, he embarked on a journey to Seto city, a hub for ceramic ware production, to master pottery.
