Edo Period: Vessels of 'Function'—Everyday Tableware That Democratized Porcelain

In the Edo period, porcelain was a luxury item exclusive to the privileged classes. This all changed with the arrival of Hasami ware's "Kurawanka-wan" bowls, which had a massive impact on Japan's culinary culture. The introduction of these bowls sparked what could be called the "democratization of everyday tableware," bringing porcelain into the kitchens of the common people for the first time.

Kurawanka-wan bowls were known for being thick, sturdy, and remarkably affordable. They featured simple patterns like arabesques or five-petaled flowers, hastily painted with a blue pigment called gosu. The name itself originates from the small boats on Osaka's Yodo River, where vendors sold food and drinks, calling out, "Sake kurawanka, mochi kurawanka?" ('Care for some sake, care for some mochi?'). These were true daily-use items, so commonplace that people used them casually and sometimes even tossed them into the river. This is archaeologically confirmed by the vast number of Kurawanka-wan bowls excavated from Edo-period sites all over Japan.

In this era, the most prized quality of Hasami ware was, above all, 'functional practicality.' Durability and affordability, which allowed anyone to use the pieces without a second thought, were far more important than aesthetic beauty or artistry. The town of Hasami transformed into a massive production hub to meet this demand, and by the late Edo period, it became Japan's top producer of blue-and-white porcelain. At the same time, Hasami was also producing "Comprador bottles"—robust porcelain containers for exporting Japanese soy sauce and sake. These were designed to meet Dutch specifications and were shipped to Southeast Asia and Europe via the Dutch East India Company. The existence of these two distinct product lines—affordable Kurawanka-wan for the domestic market and functional Comprador bottles for export—demonstrates Hasami ware's early ability to adapt to diverse market demands.
