Zanthoxylum ailanthoides, also called ailanthus-like prickly ash,[1] (Chinese: 椿叶花椒; pinyin: chun ye hua jiao, lit.

"edible shān zhū yú"; Japanese: カラスザンショウ, からすのさんしょう[5] karasu-zanshō, karasu-no-sanshō, lit.

"crow prickly ash") is an Asiatic plant of the prickly-ash genus Zanthoxylum, natively occurring in forest-covered parts of southeastern China, Taiwan, Southeast Asia, and Japan from Honshu southward.

[7] The piquant fruit serves as a local substitute for the ordinary red-pepper in China before the Columbian exchange.

Z. ailanthoides is not normally exploited for human consumption in Japan, except by the prehistoric people from the Jōmon period.
