The Japanese kanji 高 means High, Tall, or Expensive. The kun’yomi (Japanese reading) pronunciation of the Kanji 高 is “taka” (たか) as in the words taka-i (たか-い), taka-maru (たか-まる), and taka-meru (たか-める). The on’yomi (Chinese reading) pronunciation of 高 is “ko” (コウ). The Kanji 高 for “tall” or “high” frequently appears in Japanese names, and in that case, it is pronounced as “ka” (か), “ko” (こ), “joi”
