burial urn; funerary urn
Archaeological term for a large earthenware jar used as a coffin, often with a two-storey structure (upper and lower sections).
Many Yayoi-period burial urns were excavated from this site.
Burial urns were used mainly for burying infants and adults.
Compound of 甕 (かめ, 'earthenware jar') and 棺 (かん, 'coffin'). The reading かめかん is a straightforward combination of the on'yomi of the second character and the kun'yomi of the first, reflecting its specialized archaeological usage.
