What Time Machine does

Time Machine Co., Ltd. (タイムマシーン株式会社) is a Tokyo-based private company founded in February 2010 by Mizuno Yoshio and Shimano Shunnosuke. It develops and sells the ACALA family of cloud-connected IoT temperature and humidity monitoring systems, targeting HACCP-driven compliance needs across Japan's food manufacturing, hospitality, logistics, agriculture, and pharmaceutical sectors. The product portfolio includes ACALA MESH (mesh-network wireless sensors for wide-area facilities), ACALA FT (NFC handheld core temperature measurement for cooking/process records), ACALA MOBILE (GPS-enabled cold-chain transport monitoring), ACALA FACE (AI-camera body temperature and identity authentication), and the legacy ACALA THERMO cloud service. The underlying architecture combines battery-powered wireless sensors, gateways, and cloud applications using SmartMesh IP networking technology licensed through a 2015 partnership with Linear Technology.

The company operates a Product-as-a-Service (PaaS) model with zero upfront hardware costs and monthly subscription fees. Time Machine retains ownership of all deployed sensors, performs proactive battery monitoring and replacement, reuses hardware components where feasible, and stores up to two years of time-series data per site. Distribution is primarily direct sales through the Tokyo headquarters supplemented by a 2017 channel partnership with NTT docomo, which provides IoT platform integration and access to docomo's enterprise customer base. Go-to-market emphasizes content marketing via a large HACCP knowledge blog, industry exhibitions (Food Safety Japan, International Hotel Restaurant Show, Wireless Japan), and consultative selling with free consultation requests driving bottom-of-funnel conversion.

The company has accumulated more than 60 disclosed enterprise customers including Yoshinoya, Prince Hotels, Hyatt Place Kyoto, Sumitomo Chemical, Imuraya, Fujiya, Tonami Transport, Fukuoka Transport, and Compass Group Japan, with deployments spanning Sushi restaurants, hotels, food factories, logistics fleets, and agricultural facilities. It has received four industry awards (MCPC 2018 Special Prize, 29th SME New Technology Award 2017, Tokyo World Launch Competition Special Prize 2021, 26th Nikushoku Excellent Food Machinery Award 2023) and participated in the Frozen Economy Lab consortium since 2022. The company is bootstrapped with ¥5,000,000 registered capital, no disclosed venture or growth funding, and operates exclusively within Japan.
