## Abstract The wood powder of __Cryptomeria japonica__ (Japanese cedar) was liquefied in phenol, with H~2~SO~4~ and HCl as a catalyst. The liquefied wood was used to prepare the liquefied wood‐based novolak phenol formaldehyde (PF) resins by reacting with formalin. Furthermore, novolak PF resins w
