This stunning bowl is one of the pinnacles of Eiraku ware.

The rich legacy of the Zengorō family, known as the Eiraku family, is deeply rooted in pottery. The lineage began with the first Zengorō, who crafted Doburo (clay braziers) for Sakai's Tea master, Takeno Jōō, earning the title Doburo Zengorō. The second-generation Zengorō lived in Sakai, while the third generation and beyond established themselves in Kyoto, making Doburo and Tea bowls. Under esteemed Kobori Enshū's orders, the family received a copper seal with "Zengorō," a mark used until the ninth generation.

In 1788, a major fire destroyed their residence and seal, but the Eiraku family, led by the tenth-generation Ryōzen, rebuilt with support from the prestigious tea practitioners.

In 1827, the eleventh-generation Zengorō　Hōzen was honored with an invitation to the kiln opening at Nishihama-goten by Tokugawa Harutoshi, the tenth Kishū Daimyo lord. In a gesture of profound gratitude, he was presented with a silver seal inscribed with the name 'Eiraku.' This marked a significant transition in the family's history, as from the twelfth generation, Kazen, the family officially adopted the Eiraku surname.
