The Subaru Justy is a subcompact hatchback manufactured and marketed by Japanese automaker Subaru since 1994. The company has marketed a rebadged variant known as the Daihatsu Boon (second generation), at the 2007 Frankfurt Motor Show with could be optioned with a 1.0 or 1.2-litre inline-3 engine, front/four wheel drive, electronically controlled continuously variable transaxle, or a 5-speed manual transaxle. For the 2010 model year, the Justy was replaced with the Subaru Trezia. The Justy nameplate was revived in November 2016 as a rebadged Toyota Tank and its twin counterpart the Toyota Roomy and Daihatsu Thor.
__TOC__
First generation
Originally designed and manufactured in Japan, the Justy was introduced in Japan for 1984 model year as a widened and stretched version of the Rex kei car, using the same doors and other pressings. To Japanese buyers, it was longer and wider and had an engine larger than kei car dimension regulations outlined, while keeping the engine displacement just under 1000 cc to minimize the annual road tax obligation. The electronically controlled, continuously variable "ECVT" transmission was introduced in February 1987. Production of this model was limited to 500 per month due to limited supplies of steel bands from Van Doorne transmission, but as the Justy ECVT was not an unqualified success, this was not a real problem. When supplies later increased, Subaru chose to use them for the smaller Rex instead.
In Taiwan, Subaru marketed a version of the Justy with a sedan-style body and an uprated fuel injected EF12 engine called the Tutto. Taiwanese Subarus were assembled by their local partner Ta Ching.
United States
Justy models manufactured in Japan were marketed for model years 1987-1994 with the 1.2 engine. Early models featured a low-roof, and beginning with the 1989 models, featured a high roof. The Justy received 4WD as an option in 1988, and all models were equipped with Multi Port Fuel Injection late in 1991. For 1990, the automatic front two-point motorized passive seat belts were introduced for 3-door FWD models in the United States market only, while manual front seat belts were retained on the 4WD models. A five-door model was available from 1990 to 1994, only with 4WD. A 1995 model was offered in Canada.
Norway
The Subaru Justy (registered as "Justy/Trendy" in Norway) was available from late 1984 with optional 4×4 and the EF10 engine. The 4×4 version came with a version of the engine with a two barrel carburetor, while the FWD version only produced with a single barrel carburetor. The 4×4 version had a factory top speed of and could accelerate from in roughly 16 seconds. Gear ratios were identical on the 1.0- and 1.2-litre versions. Stock tire dimensions on the 1.0-litre version had tire size 145-SR-12 and the 1.2-litre version had 165-65-R-13. The turning circle was and the fuel tank could hold 35 litres.
Taiwan
In 1989, Fuji Heavy Industries signed a long-term contract with Taiwanese automotive manufacturer Ta Ching Motor Co. who developed the Subaru Tutto notchback sedan, which was unique to Taiwan and based on the Justy hatchback.

Drivetrain
Initially, the Justy was equipped with a 1.0 or 1.2 litre EF three-cylinder engine and either a manual transmission or a continuously variable transmission with either front wheel drive or on-demand four wheel drive. A CVT type transmission (a pushbelt system) was employed because with a conventional automatic transmission, performance would have been unacceptable due to the small-displacement, relatively low-power 3-cylinder engine. Also, within urban areas in Japan where the Justy was an affordable choice, speed limits often do not exceed . In North America, due to larger roads with higher speed limits and longer distances, the CVT was considered unreliable, but this has not been the case in other countries.
In 1989, the gear ratios were changed, the front brakes and outer axle shafts were made larger, the rear differential was reinforced and the front axle shafts were changed to identical lengths thanks to an intermediate extension shaft.
The European Justy sold from 1994 to 2001 was a rebadged second generation Suzuki Cultus built in Hungary. It used a 1.3 SOHC 8V, G13BA Suzuki engine with a Suzuki 5-speed manual transmission and AWD via a viscous clutch as standard.

Rebadged models
After 1994, rebadged models from other manufacturers carried the Justy nameplate:
- In 1994, Subaru introduced to the Europe market a rebadged second generation Suzuki Cultus carrying the Justy nameplate. Manufactured at Suzuki's Esztergom, Hungary plant, these were available in 3 and 5 door models, both with full-time all wheel drive as standard.
- In 2004, a rebadged Suzuki Ignis carried the G3X Justy nameplate in Europe, this model is available with a Suzuki M13A or M15A engine, and also equipped as standard with AWD.
- For the 2007 model year, a rebadged Toyota Passo/Daihatsu Boon revived the Justy nameplate with the Toyota 1KR-FE 1.0 L engine. It was only available with front wheel drive, unlike previous Justy models since the first one in 1984 that had either optional or standard 4WD/AWD.
- In late 2016, a rebadged Toyota Roomy/Tank/Daihatsu Thor revived the Justy nameplate with the Toyota 1KR-FE 1.0 L engine.
