The Japanese style calligraphic works in the time when the style was completed, including the calligraphic works of the sanseki calligraphers in the middle era of the Heian period and kohitsu, are particularly called jodai (ancient) style (calligraphic works), for differentiating these from calligraphic works in Japanese styles during the Kamakura period or later.
また、平安時代中期の三跡の書や古筆など完成期の和様書を指して特に上代様と呼び、鎌倉時代以降の書流による和様書と区別している。
