The Fuji Japanaese Simulants (FJS 1, 2 and 3) were produced by the Shimizu Corporation to simulate lunar mare soils. All three used a base of basalt from near Mt. Fuji, with versions 2 and 3 spiked with olivine and/or ilmenite. FJS-3 (with ilmenite) was meant to represent a high-Ti mare soil.

All three simulants were produced by progressively crushing the raw materials until a particle size distribution was obtained that fell within the range of Apollo soils.

The status of the FJS simulants is not known, but given how long ago they were described it is unlikely they are still available.
