AERO (1925–1927)

AERO was a Japanese motorcycle brand developed by Narazo Shimazu, a foundational figure in Japan's motorcycle history. Before World War I, Shimazu built motorcycles under the NS name, and by 1925, he introduced the AERO. Manufactured until 1927, these motorcycles featured single-cylinder engines in two displacements: 250cc and a larger 633cc model. They stood as some of the earliest examples of Japan's efforts to establish a domestic motorcycle industry.

🔧 Notable Models

AERO 250cc: A lightweight single-cylinder model, ideal for early commuting and basic transport needs.
AERO 633cc: A more powerful version that demonstrated Shimazu's mechanical skill and innovation at the time.

🏁 Legacy

Though short-lived, the AERO brand represents a milestone in Japanese engineering history. Narazo Shimazu's work laid the foundation for the vibrant and world-renowned Japanese motorcycle industry that followed. His designs embodied creativity and determination during a time when motorcycles were rare and largely imported.

AIKOKU (1934)

AIKOKU was a lightweight Japanese motorcycle brand established in 1934 by Tetsuji Makita. These motorcycles were small-displacement machines, typically around 50cc, designed for simplicity and efficiency during an era when Japan was developing its domestic motorcycle capability.

The bikes were notable for their use of Meguro gearboxes—a reputable component known for durability and smooth shifting—and side-valve (SV) engines supplied by both JAC and HMS. Despite their limited power output, AIKOKU motorcycles were reliable and accessible, catering to new riders and utilitarian markets.

🔧 Key Features

Engine: 50cc side-valve (SV) engines built by JAC and HMS
Gearbox: Supplied by Meguro, one of Japan's top gearbox producers at the time

MARUSHO (1964–c.1969)

MARUSHO was a Japanese motorcycle brand active from 1964 to around 1969, known for producing high-quality, BMW-inspired motorcycles. The company operated out of the former Lilac factory, continuing a legacy of technically sophisticated motorcycle design and precision craftsmanship.

Marusho's most notable model featured a 498cc transverse-mounted overhead valve (OHV) flat-twin engine. This unit-design engine was paired with a four-speed gearbox and a shaft drive to the rear wheel, mimicking the engineering style of BMW’s iconic boxer twins. The machine was distinguished by its smoothness, stability, and mechanical refinement, setting it apart from many other Japanese motorcycles of the time.

The Marusho was aimed primarily at the American market, where there was growing interest in European-style motorcycles. Its combination of performance, durability, and touring capability made it attractive to riders looking for an alternative to both British twins and German boxers.

🔧 Key Features

Engine Type: 498cc transverse-mounted OHV flat-twin
Transmission: Four-speed gearbox
Drive System: Shaft drive
Design Influence: Strongly inspired by BMW motorcycles
Market Focus: Primarily exported to the USA

🏁 Legacy

MARUSHO represented a technically ambitious effort to bring European-style touring motorcycles to the Japanese export market. Though production was short-lived, the brand’s flagship flat-twin models are prized by collectors today for their rarity and engineering excellence. As a continuation of the Lilac tradition, Marusho played a quiet but significant role in Japan’s mid-century motorcycle evolution.

MITSUBISHI (1948–1964)

MITSUBISHI, one of Japan’s largest and most diversified industrial conglomerates, ventured into the motorcycle and scooter market from 1948 to 1964. During this period, the company achieved notable success with its well-known Pigeon scooter series, which became a popular choice for personal mobility in post-war Japan.

The Pigeon scooters were powered by a range of engines, starting with a 115cc two-stroke and extending to a 210cc four-stroke version. These scooters were recognized for their reliability, smooth performance, and solid construction—characteristics aligned with Mitsubishi’s engineering reputation across industries. The Pigeon series gained traction among commuters looking for affordable, efficient, and stylish transportation during Japan’s rapid urban development.

🔧 Key Features

Product Line: Pigeon scooters
Engine Types: Two-stroke and four-stroke
Displacement Range: 115cc (2T) to 210cc (4T)
Design Focus: Urban transport, reliability, and comfort
Production Period: 1948 to 1964

🏁 Legacy

Though Mitsubishi eventually exited the two-wheeler market, the Pigeon scooters remain an iconic part of Japan’s post-war motorization. Their success demonstrated Mitsubishi’s ability to apply its industrial expertise to consumer mobility. Today, surviving Pigeons are rare collector items, cherished for their quality build and role in shaping everyday transport in mid-20th century Japan.

MIYATA (1909–1964)

MIYATA was one of Japan’s oldest industrial manufacturers, originally established in the early 20th century and active in motorcycle production from 1909 to 1964. Following World War II, the company became best known for producing motorcycles under the Asahi brand, a name associated with solid engineering and British-inspired designs.

Among Asahi’s offerings were a range of machines including 249cc side-valve and overhead valve (OHV) singles, 344cc overhead valve singles, and larger 496cc vertical twins, also using OHV architecture. These models were robust and clearly influenced by British motorcycles of the time, with upright frames, classic tank styling, and solid road performance. In addition, Miyata produced 123cc two-stroke motorcycles, offering more accessible mobility options for post-war Japanese riders.

Despite their quality, Asahi motorcycles were primarily made for the domestic market and were never exported to Europe. This focus limited their international recognition but allowed the company to serve Japan's rapidly growing two-wheeler market with consistency and reliability.

🔧 Key Features

Main Models: Asahi-branded motorcycles
Engine Types: SV and OHV singles, OHV vertical twins, and two-strokes
Displacements: 123cc (2T), 249cc (SV/OHV), 344cc (OHV), 496cc (OHV twin)
Design Influence: Based on British motorcycle engineering
Export Status: Not exported to Europe

🏁 Legacy

As one of Japan’s longest-standing manufacturers, MIYATA played a key role in both pre- and post-war motorcycle development. Its Asahi motorcycles reflected strong engineering with a clear nod to British design standards. Though the company ceased motorcycle production in 1964, its legacy remains deeply embedded in Japan’s early motorcycling history, particularly for its contribution to reliable, domestically-focused two-wheeled transport.
