The bus uses components originally developed for the Toyota Mirai, a mid-size fuel cell sedan.

The name Sora is an abbreviation of the words Sky, Ocean, River and Air and refers to the water cycle.

With a capacity of 78 passengers, the Sora uses fuel cells to power the bus, in which 10 tanks carrying 600 litres of hydrogen feeds two sets of polymer electrolyte fuel cells which can produces an output of 116 kW (155 hp).

The bus has an environment monitoring system based on eight cameras located inside and outside the vehicle, combined with radar and a collision warning system, to detect pedestrians and cyclists in the vicinity and alert the driver to their presence using audible and visual signals.
