Ultimate Japanese Microcar Museum Guide 2025 Edition

Japan’s remarkably efficient road network, stretching over a million kilometers, supports the daily commute of millions, even within its densely populated urban landscapes. While this might suggest inevitable gridlock, the Japanese have long championed a pragmatic solution: the Kei car. However, beyond these remarkably compact vehicles lies an even more niche and fascinating world of microcars, and one dedicated collector is on a mission to preserve their unique and often overlooked legacy.

The Kei Car: Japan’s Tiny Titan of Transportation

Kei-jidosha, or “Kei car,” represents the smallest category of street-legal automobiles in Japan. Over the decades, this class has given rise to some of the most uniquely designed and surprisingly practical vehicles imaginable. Powered by small engines and often sporting tires that appear almost comically undersized, Kei cars offer an ingenious solution for navigating the challenges of crowded urban environments, especially in an era of increasingly large automobiles. They are a testament to efficient design and resourceful engineering.

The Kei car emerged in 1949, during the post-World War II era. Japan faced the monumental task of rebuilding its population and economy, but limited resources made traditional vehicles unaffordable for many. Thus, the “light vehicle” class was born. Initially, regulations capped engine displacement at 150cc for four-stroke engines (or 100cc for two-stroke engines). This limit was later expanded to 360cc in the mid-1950s. The Subaru 360, launched in 1958, is widely regarded as the first mainstream Kei car, cleverly accommodating four passengers within a compact ten-foot frame. Its innovative design and affordability made it a symbol of Japan’s post-war recovery and ingenuity.

By the 1990s, Kei car engine capacity had increased to 660cc. Manufacturers embraced forced induction technologies like turbocharging to enhance power and efficiency, leading to iconic models such as the Suzuki Cappuccino, Autozam AZ-1, and Honda Beat. These models, with their distinctive styling and spirited performance, cultivated a devoted cult following. While power output was capped at 63 horsepower through a gentlemen’s agreement among manufacturers, dimensions have remained consistent since 1998: a maximum length of 3.4 meters, a maximum width of 1.48 meters, and a maximum height of 2.0 meters. It’s important to note that Kei cars are not subject to the same stringent safety standards as larger passenger vehicles, which contributes to their limited official sales outside of Japan. While not inherently unsafe, they likely would not perform favorably in standardized crash tests like Euro NCAP, a significant factor hindering their global appeal, despite their inherent practicality.

Beyond Kei: Exploring the Realm of Microcars

Kei cars account for a substantial portion of all vehicle sales in Japan, underscoring their enduring popularity and practicality. However, preceding the rise of the Kei car, an even smaller vehicle trend emerged, making even the most compact Kei cars seem almost gargantuan in comparison. These microcars were so small and low-powered that they didn’t even necessitate a full driving license, ushering in a truly unique and somewhat eccentric era in Japanese motoring during the 1970s. Mitsuoka Motors, a company celebrated for its eccentric and often whimsical creations, played a pivotal role in pioneering this microcar movement. They fearlessly challenged conventional automotive design and explored the boundaries of miniaturization.

Before Mitsuoka gained recognition for reimagining Mazda Miatas into charmingly retro Jaguar Mark II clones, they were primarily engaged in importing and servicing European automobiles. Susumu Mitsuoka, the company’s visionary founder, harbored a long-held ambition of creating his own vehicles, a dream he finally realized in the late 1970s. When a customer brought in a Casalini Sulky microcar for repairs, Mitsuoka encountered considerable difficulties in sourcing replacement parts. Undeterred, he embraced a resourceful spirit and leveraged his ingenuity to create Mitsuoka’s first complete car in 1982: the BUBU Shuttle-50. This marked the inception of Mitsuoka’s journey as a unique and innovative automaker.

The BUBU Shuttle-50: Mobilizing a Nation (on a Tiny Scale)

While calling the BUBU Shuttle-50 a “car” might be a slight overstatement, it undeniably possessed the essential attributes of a motor vehicle, including doors, mirrors, and a windscreen. Its diminutive 50cc engine powered a single rear wheel, while two front wheels provided steering. Mitsuoka’s ambitious objective was to provide affordable and accessible transportation to all Japanese citizens. Thanks to its 50cc engine and handlebar controls, the BUBU Shuttle-50 could be operated with only a moped license, making it accessible to a wider demographic. Its rear-opening door with fold-out ramps also made it particularly suitable for individuals with disabilities. Its compact size even allowed it to fit through a standard doorway, eliminating the need for a dedicated garage. The BUBU Shuttle-50 was a testament to practical design and inclusive mobility.

The BUBU 50 quickly followed in the same year, a slightly smaller and sleeker model that also featured a 50cc engine and three wheels, but with a more conventional steering wheel. The BUBU 505-C, which strikingly resembled a quarter-scale Morgan Roadster, joined the range three years later, adding a touch of classic British motoring flair to the microcar lineup. While Mitsuoka shifted its focus to full-size vehicles in the late 1980s, their innovative microcar vision remained a part of their product portfolio until 2007. These microcars showcased Mitsuoka’s ability to seamlessly blend practicality with distinctive and often whimsical design.

The WAZUKA Microcar Museum: A Collector’s Sanctuary

Each microcar, despite its often quirky and unconventional appearance, served a specific purpose that even Kei cars couldn’t fully address. They offered even greater convenience for navigating extremely narrow roads and alleyways, and obtaining a moped license was significantly cheaper and easier than obtaining a full driving license. The microcar market flourished until the late 1980s, when regulations changed, requiring a full driving license for operation and drastically reducing their appeal. This regulatory shift effectively ended the microcar boom, relegating them to the realm of niche vehicles and collector’s items.

However, decades later, Koru Hasegawa, based in Wazuka, is on a dedicated mission to preserve this unique and often forgotten era of Japanese motoring. “I got my first microcar nearly 30 years ago,” he explains. “I’ve always enjoyed small vehicles, and I was given my first microcar. It had been abandoned in a corner of a car shop, so I spent time restoring it and started driving it around. It was so much fun, and the reaction from other people was amazing. I knew I wanted another microcar, so I started looking around and researching their history.” Hasegawa’s passion for microcars is fueled by a desire to preserve a unique and important piece of Japanese automotive history.

Finding a good, working microcar can be as challenging as finding a needle in a haystack. These vehicles were never produced in large numbers, and many have been lost to time or neglect. Hasegawa’s collection represents a significant effort to locate, restore, and preserve these tiny titans of transportation. His museum in Wazuka offers a glimpse into a bygone era, showcasing the ingenuity and resourcefulness of Japanese automotive design. It’s a testament to the fact that sometimes, the smallest things can have the biggest impact.
