What Green Cab does

Green Cab (株式会社グリーンキャブ) is a Tokyo-headquartered, family-owned passenger transportation company founded in September 1952, operating a diversified mobility services portfolio across the Tokyo metropolitan area, Kanagawa, and via group subsidiaries in Miyagi, Ibaraki, Nagano, and Fukushima. The core business is a 24-hour metered taxi service across Tokyo 23 wards, Musashino, Mitaka, and Kanagawa, supported by a fleet of 1,344 taxis (plus 42 hire vehicles, 13 chartered buses, 17 welfare buses, and 7 welfare taxis, totaling 1,423 vehicles) distributed across 10 company-owned branches. Revenue is generated primarily through distance-and-time metered fares, fixed-fare routes to Haneda/Narita airports and Tokyo Disney Resort, corporate taxi tickets redeemable across the nationwide Nice Taxi Wide Network (~25,000 partner taxis), premium hire/chauffeur services, chartered bus rentals, welfare transport for elderly and disabled facilities, and ancillary vehicle maintenance and storage operations.

The company's technology layer rests on three pillars: (1) its own wireless dispatch system, pioneered nationwide in 1958, (2) integration with the S.RIDE taxi dispatch app — a joint venture with Sony Group, Sony Payment Services, and four other Tokyo taxi companies that provides AI-powered dispatch, advance reservation, fixed fares, and cashless in-vehicle tablet payment, and (3) the Nice Taxi Wide Network partnership for nationwide corporate ticket acceptance. Green Cab participates in S.RIDE across at least Tokyo, Kanagawa, Saitama, Chiba, Ibaraki, and Miyagi, with the network exceeding 10,000 vehicles. The company is also investing in back-office digital infrastructure (invox electronic invoicing, SBI 請求QUICK/消込QUICK cloud receivables) that has automated approximately 80% of bookkeeping operations.

Green Cab is privately held and family-controlled, with Takano Kimihide serving as President and Representative Director since 2018, succeeding founder Takano Masahiro who became Chairman. The Green Cab Group comprises approximately 30 subsidiaries spanning taxi, highway and community bus, parking, real estate, petroleum/LPG supply, driving school, and solar power businesses; combined group capital stands at approximately 851.8 million yen (FY2017) and group sales at approximately 31.4 billion yen (FY2017). The company holds a three-star chartered bus safety evaluation, ISO 14001 environmental certification, Green Management certification (since 2009), and a two-star workplace certification from the Ministry of Land, Infrastructure, Transport and Tourism (November 2024). Customer segments span individual consumers, corporate accounts, healthcare facilities (with dedicated taxi stands at Tokyo Medical University Hospital and the Japanese Red Cross Medical Center), and government/contracted welfare transport — making it a multi-segment B2B/B2C operator rather than a single-channel platform.

Scale indicators8 records

Recent moves13 records

Expansion highlights6 records

Broad incumbents

• Uber Japan: Global rideshare platform actively expanding Uber Taxi in Japan; competes for the same rider wallet share, particularly in Tokyo, and pressures traditional dispatch economics across the industry.

Others

• S.RIDE Inc. Sony Group joint venture operating the AI-powered taxi dispatch app that Green Cab uses. Strategic technology partner and core distribution channel — not a taxi operator itself but the platform orchestrator for Green Cab's digital demand.

Emerging players

• Hokkaido Kosoku Bus / Intercity Highway Bus Operators: Long-distance highway and charter bus operators comparable to Green Cab Group's Chikuma Bus and Joban Bus subsidiaries in the charter bus and intercity highway bus segments.
• GO Inc. Japan's leading taxi-hailing app (formerly JapanTaxi / MOV), backed by Nihon Kotsu. Competes with S.RIDE for app-based dispatch, making GO a direct platform competitor to the S.RIDE/Green Cab stack.

Regional players

• Tokyo Musen Co-operative Taxi Association: Cooperative association of licensed Tokyo taxi operators providing shared dispatch; represents the cooperative owner-driver model that contrasts with Green Cab's corporate-fleet structure and competes for the same passenger base.
• Checker Cab (Yokohama): Yokohama-based taxi operator with significant Keihin presence where Green Cab also operates. Comparable fleet size and airport route business, but focused on Kanagawa rather than central Tokyo.

Direct peers

• Hinomaru Limousine: Major Tokyo chauffeur/hire operator with strong corporate and executive clientele; competes directly with Green Cab's hire service for premium chauffeur-driven trips and corporate accounts.
• Nihon Kotsu (Japan Taxi): Largest Tokyo taxi operator with the dominant corporate and hotel account base; competes head-to-head with Green Cab for airport, hire, and corporate taxi business in central Tokyo. Direct functional and geographic overlap in passenger ground transport.
• Daiwa Motor Transportation: Tokyo-headquartered taxi and bus operator with comparable services across taxi dispatch, hire, and charter bus. Operates as one of the founding S.RIDE joint-venture partners, mirroring Green Cab's platform strategy.
• KM Group (Kokusai Motorcars / International Motorcars): Tokyo taxi group operating multiple brands including Kokusai Motorcars; competes with Green Cab for corporate, tourism, and airport demand and is also a S.RIDE network participant.
