What car sharing japan co., ltd. does

Car Sharing Japan Co., Ltd. operates the Mitsui no Carshares (三井のカーシェアーズ) service, a round-trip, station-based car sharing platform serving individual consumers and corporate clients across approximately 25 of Japan's 47 prefectures. The service was previously known as Careco Car Sharing (カレコ・カーシェアリング) and was rebranded to align with its parent, Mitsui Fudosan Realty Co., Ltd. (三井不動産リアルティ株式会社), part of the Mitsui Fudosan Group. Members reserve vehicles through a web member portal or a proprietary mobile application, unlock cars via smartphone or membership card at designated stations, and return them to the same station at the end of the rental period.

The underlying platform is a conventional station-based car sharing system: a web member portal and mobile app handle 24/7 reservation, vehicle unlock/lock, payment, and account administration; station search supports queries by address, municipality, landmark, and proximity to Shinkansen stations, airports, and hotels; and a Google Maps-integrated drive simulation tool estimates routes, time, distance, and rental cost. The fleet spans compact cars, SUVs, minivans, sports cars, sedans, EVs, and premium models including Lexus NX, with ongoing 2026 additions of the Nissan X-TRAIL, New Freed, New Spacia Gear, and New Forester.

Revenue is generated on a usage-based model combining time fees and distance fees, structured into a Basic Plan (880 yen monthly fee with time-fee discounts), a Monthly Fee Free Plan (no monthly fee, higher per-use rates) for individual consumers, and Corporate Basic and Corporate Gold plans for businesses and sole proprietors. Optional add-ons include the Trouble Anshin Support accident/damage protection product. The service also runs a B2B station-host onboarding program allowing parking-lot owners (monthly lots, apartment complexes, hotels, offices) to convert idle capacity into car sharing stations, and ties member benefits into the broader Mitsui ecosystem (V-points, Mitsui Shopping Park point campaigns, Nippon Rent-A-Car discounts, and Mitsui Garden Hotels accommodation plans).
