These kilns were built after the cellar kilns, and are cellar kilns that were built in a semi-ground or above-ground style. These kilns were built from the Muromachi period (1333-1573) to the Edo period (1603-1868), and are seen in kiln sites where pots and jars were fired, some of which remained until the Meiji and Taisho periods. All of these types of kilns were built on the ground and can be found in various locations, but there are some differences depending on the topography of the area. Some large kilns have auxiliary openings at intervals of about 7.0 cm from the bottom to the top, in addition to the lowest opening. All of these kilns have a sand bed, but they are designed to keep the level of the kiln by using kiln tools according to the slope of the kiln. A remarkably long example of a large kiln is the snake kiln at Tamba Tachikake (Sasayama City, Hyogo Prefecture). The term “Seto large kiln” has a slightly different meaning from the one on the right. When Karatsu-style climbing kilns were introduced to Mino (Gifu Prefecture) in the early Keicho period (1596-1615), they were called small kilns, and the earlier Seto-style climbing kilns were collectively called large kilns. The “large” in “large kiln” does not mean “large” or “small” but “original” or “main”.
