The , literally “co-signatory”, was the assistant to the ''
shikken'' (
regent) of the
Kamakura shogunate in
Japan.
The rensho placed his signature next to that of the ''shikken'' on official orders. In 1224 the third ''shikken''
Hōjō Yasutoki appointed
Hōjō Tokifusa as the first ''rensho''. From then on, the ''rensho'' was chosen from influential members of the
Hōjō clan, but not from the main line of the clan (''
tokusō''), with the one exception of
Tokimune, who temporarily occupied the position from 1264 to 1268.
