  As a new scheme of treating the tensor interaction of the nucleon-nucleon
interaction, there is a proposal of a tensor-optimized shell-model (TOSM) for
the study of medium and heavy nuclei. The TOSM includes the deuteron-like
tensor correlation and provides quite a good reproduction of the binding energy
and the size of $^4$He as compared with rigorous few body calculations. We
propose a tensor-optimized few-body model (TOFM) using the spirit of the TOSM
approximation in the few body framework with bare nucleon-nucleon interaction.
We find that the TOFM can account for the strength of the tensor interaction
very well and almost reproduces the full energy and various energy components
as compared with rigorous few body calculations.
