Japan’s ultra-compact mobility and mini-car class

In Japanese law a minicar is two things at once. The Road Traffic Act treats it as an ordinary motor vehicle, so it needs a car licence and may do 60 km/h (37 mph); the vehicle law treats it as a moped, so it needs no inspection and no garage certificate, but may not use the expressways. It has one seat, and an engine of over 20 cc and up to 50 cc, or a motor of over 0.25 kW and up to 0.6 kW, and it may be as long as 2.5 m (8 ft 2 in), as high as 2.0 m (6 ft 7 in) and as wide as 1.3 m (4 ft 3 in).source 1 Some makers called theirs microcars, so as not to be confused with toy cars, which are also ミニカー.source 1 The class began as an all-weather moped, a scooter with a roof and extra wheels. Its boom of the early 1980s, when it could be driven on a moped licence, is told with the Japanese 50 cc minicars; it ended on 15 February 1985, when a car licence became compulsory.source 1

Exhaust rules of September 2007 then drove every maker of petrol minicars out of business except Takeoka, and electric minicars took over (more in electric microcars).source 1 From July 2012 7-Eleven bought Toyota Auto Body’s electric Toyota COMS in numbers for its deliveries, and put them on the streets.source 1 Tighter safety rules of April 2018 ended new registrations of kart-like minicars and required seat belts, and in June 2021 the load limit rose from 30 kg to 90 kg.source 1

The transport ministry, for its part, wanted room on the road for a new kind of small vehicle, and defined it like this.source 2source 3

自動車よりコンパクトで小回りが利き、環境性能に優れ、地域の手軽な移動の足となる１人～２人乗り程度の車両

In January 2013 the ministry began to certify such vehicles, up to 3.4 m long and of 0.6 to 8 kW, for public roads in designated areas and on conditions.source 2source 3 Nissan put its version of the Renault Twizy, the Nissan New Mobility Concept, into a one-way car-sharing scheme in Yokohama from 11 October 2013, and in its first month 2,700 people joined.source 4 Toyota tried the tilting Toyota i-Road, which leans on its two front wheels and steers with its rear one, and showed a test version at the Tokyo Motor Show that year.source 5 A class of type-designated ultra-compact cars followed, and the Toyota C+pod, which Japanese Wikipedia describes as the first of them, was sold to companies and local authorities from 25 December 2020 until 2024.source 6 The cars follow in the order they appeared.

Takeoka Jidōsha Kōgei was a sign-maker in Toyama, skilled with glass fibre, and became a company on 1 October 1982. It built the BUBU Shuttle 50 for Mitsuoka in 1981 and, after the two fell out over price, its own minicar, the Abbey.source 7 The first Abbey ran on three wheels, a pair in front and one behind, with bar steering and a scooter engine, and was built for a disabled customer who wanted a scooter with a roof. The four-wheeled second type of 1984 was an unexpected success, a Sport followed in 1986, and the fourth type, from 1988, became the long-running Abbey Carrot, later with Honda four-stroke scooter engines or a Yamaha Jog’s.source 7

Takeoka kept going when the others stopped. Part of the reason, Japanese Wikipedia says, was its disabled customers, who told it they could not get about without its cars; it builds hand controls, bar steering and other adaptations to order.source 7 From 1996 it worked on electric cars with Hokuriku Electric Power: the Milieu of 1999 and the Milieu R of 2000, the Friendly Eco of 2002, which took a wheelchair, and the T‑10 of 2011–⁠12. From 2016 it imported the Lala, a single-seat electric car built in China, and from 2003 it had imported the Indian REVA as a kei car.source 7 By the company’s account nearly half its output went abroad.source 7 The fourth Abbey passed 2,000 in 2024. On 19 June 2025 Takeoka announced the end, because no new 50 cc engines could be had after the emission rules of November 2025, and offered a Final Edition of 100 and ten Gold Abbeys to close.source 7

Toyota showed the e-com at the 32nd Tokyo Motor Show, in 1997, as a two-seat commuter for the city. It had an 18.5 kW (25 PS) permanent-magnet motor driving the front wheels and a nickel-metal-hydride battery that charged from a 100 V socket in about six hours, and it reached 100 km/h (62 mph) and ran about 100 km on a charge. It was 2,790 mm (110 in) long and weighed 770 kg (1,698 lb).source 8 From 1999 to 2006 e-coms served in Toyota’s “Crayon” car-sharing trial, in which members unlocked them with IC cards, in the cities of Toyota, Kariya, Anjō and Ōbu, and in other places, Kyoto among them. At Toyota’s MegaWeb in Tokyo, the e-com Ride carried visitors round an automated guideway until 30 December 2010.source 8

Mitsuoka Motor of Toyama, best known for its retro-styled conversions of other makers’ cars, built the MC-1 from 1998 to 2007, a minicar under the slogan “Microcar for your life”.source 9 A 50 cc single, 49 cc from 2005, sat in the middle with a CVT, and gave it about 6 hp and 50 km/h (31 mph). It was 1,755 mm (69 in) long and weighed 160 kg (353 lb), its body was plastic and its doors were fabric, and it had a three-point belt but no airbag. It cost ¥385,000 at launch and ¥488,250 by 2005.source 9 The MC-1 T, 10 kg heavier, had a load bed and mountings for a delivery box, and the MC-1 EV a motor of 0.59 kW.source 9 No count of MC-1s has been found.

Nissan showed the Hypermini as a concept at the 1997 Tokyo Motor Show, announced the production car in September 1999 and put it on sale in February 2000, at ¥4,000,000 with a fixed 200 V charger.source 10source 11 It was Satoshi Wada’s last design for Nissan, the first electric car sold in Japan with full type designation, and the only kei car Nissan ever developed and built itself.source 11 Its frame was extruded aluminium and its panels recycled plastic. A 24 kW motor at the back drew on an 8.1 kWh lithium-ion battery under the floor, which Nissan called the world’s first manganese lithium-ion battery for a car, and it ran on run-flat tyres, a first for a Japanese car. It charged by induction, through a paddle, at 200 V in about four hours, and reached 100 km/h and about 115 km (71 miles) on a charge.source 10source 11 In January 2000 it won a prize at the New Energy Awards.source 10source 11

Hyperminis went into car-sharing trials at Minato Mirai in Yokohama, at Ebina and in Kyoto, and abroad: 15 to the University of California, Davis, on 7 November 2001, and 11 to the City of Pasadena, which Nissan took back in August 2006.source 10source 11 How many were built is uncertain: 219 by English Wikipedia, about 200 by Japanese Wikipedia, whose last known number is EA0-000202, or about 300 by Nissan’s own account as reported.source 10source 11

Honda unveiled the MC-β in November 2013 and lent it for field tests to Kumamoto Prefecture, Saitama City and Miyakojima City.source 12 It was designed around the ultra-compact categories the ministry was then discussing, and around Europe’s L7 class. It carried two adults in an offset seating layout, was about 90 cm (35 in) shorter than a typical kei car, at 2,495 mm (98 in), and turned in a radius of 3.3 m. The frame was tubular, from Honda’s motorcycle practice, and the panels plastic. A motor of 6 kW, 11 kW at peak, gave it more than 70 km/h (43 mph) and a range of more than 80 km, and it charged in under three hours at 200 V or seven at 100 V.source 12

Kazunari Kusunoki, known as Kussun, sold his car-parts business in 2018 and from 2022 developed an electric minicar at Higashihiroshima, under the name KG Motors, for Kussun Garage; a concept, the T-Box, was shown in 2022.source 13 The Mibot follows the minicar rules: one seat, 60 km/h, and a motor at the back of 0.59 kW continuous, 5 kW at peak, by English Wikipedia’s table, though its text gives 0.79 hp and 6.7 hp. A 7.68 kWh lithium iron phosphate battery gives about 100 km. It is 2,490 mm (98 in) long, weighs 430 kg (948 lb) and costs ¥1,000,000 before tax.source 13 By May 2025 it had 3,300 orders; the first car was delivered on 30 December 2025, full production was planned from April 2026, and in January 2026 Idemitsu agreed to service it.source 13

Hyperminis are kept in the Nissan Heritage Collection at Zama, and others have been sold off and turn up second-hand, though old batteries and parts are dear, and the inductive paddle no longer fits public chargers.source 11 The photographs on this page show Hyperminis in Nashville’s Lane Motor Museum in 2009 and the California Automobile Museum at Sacramento in 2022. No club, register or auction sale has been found for these cars.
