Highlights:

A model to predict the radiocaesium interception potential (RIP) from soil physicochemical properties was developed for Japanese soils.
The RIP decreased with increasing the soil organic matter content, a main factor influencing the RIP.
The soil organic matter content and the cation exchange capacity (CEC) explained 64% of the variation in the RIP.
Andosols exhibited significantly lower RIP than other Japanese soils.
The model developed here can be applied for soil types typical in the Fukushima accident affected area.
