As with the earlier concepts, the production car features a stepped roof, large windows, and a design that places space efficiency ahead of aesthetics.
A 1.3 metre-tall powered sliding rear door on the left side, a low, flat floor, grab handles, and LED illuminated seat belts should ensure easy ingress and egress from the vehicle.
Behind the rear seats is a boot with 401 litres of space according to the VDA standard, with space for two large suitcases or four golf bags.
The JPN Taxi will replace the rear-drive Comfort and Crown Comfort models as Toyota's offering to taxi owners and fleets in Japan.
Where the old three-box sedan came with a choice of LPG and diesel motors, the front-wheel drive JPN Taxi will, initially at least, only be offered with a LPG-compatible hybrid drivetrain featuring a 1.5-litre petrol engine.
Given the rigours of life as a taxi, the JPN Taxi features easily replaceable multi-part bumpers, and a "no-maintenance power water pump in the auxiliary belt system".
The JPN Taxi will be available in two trim levels: the 3,277,800 yen ($36,900) Nagomi and 3,499,200 yen ($39,400) Takumi.
For your extra yen, the Takumi model gains body-coloured bumpers, alloy wheels, LED headlamps, an extra set of vertical tail-lights, rear-seat air vents, a ceiling-mounted air circulator, and rear heated seats.
Standard features on all models include six airbags, and the Toyota Safety Sense C collision avoidance package.
No word yet on whether the JPN Taxi will offered outside of Japan, but the Comfort and Crown Comfort taxi specials were a common sight in Singapore and Hong Kong.
