We confine several ^4He particles in a nanoscale-radius spherical cage. The effective inner radius of the cage ranges from 3.5 to 10.0Å. We construct a simplified model for the system, and compute its thermodynamic quantities by an imaginary time path integral method. In this computation, we deal with ^4He particles as not only Bose particles but also distinguishable particles in order to clarify the role of particle statistics. In the boson case, kinetic energy strongly depends on the number of confined particles and cage radius. The energy difference between two statistics cases becomes considerably large in the temperature region T<2.0K. The energy difference reflects the particle exchange effect, and we evaluate the solidification condition of the system.
