KiHa 100 series

Differences from the four pre-production series cars included abandoning of the three pairs of tip-up seats near the doorways, and elimination of the dummy exterior window at the toilet position.

Broadly based on the KiHa 100–200 series cars, these are each equipped with one Komatsu DMF11HZ 330 hp engine.

The fleet is painted in an overall light blue colour scheme with "FRUITS LINER" logos.
