The IZUMI's periodization is similar to Sasaki's: Izumi classified the incipient Jomon period as 'the exploratory period,' the earlier Jomon period as 'the experimental period,' and from the early to the last Jomon period as 'the stable period.'
泉も佐々木による区分に近く、縄文草創期を「模索期」、縄文早期を「実験期」、縄文前期から晩期までを「安定期」としている。
