What T-Cloud does

T Cloud Computing Consortium (トランスペアレントクラウドコンソーシアム / Tクラウド研究会) is a Japanese research consortium established on June 6, 2012 at the University of Tokyo and led by Professor Hiroshi Esaki (江崎 浩) of the university's Department of Information Science. It investigates new computing models that emerge when devices connect with cloud systems, focusing on M2M (Machine-to-Machine) communication, IoT data flows, and the creation of next-generation device-centric markets through organic, transparent data processing.

The consortium organizes its research around three defined domains: device applications, large-scale data analytics (Big Data), and platforms. Active projects include the Smart Car (車雲) project on connected-vehicle data utilization, T-Village (a smart home project), and work streams covering smart meter and smart building applications. Study groups address security and privacy, large-scale data processing, frameworks and cloud computing, IEEE1888 standardization, and business case development. A named technical contribution is Dripcast, a transparent cloud technology for distributed privacy-preserving statistical computation. The consortium contributes to the IEEE1888 standard and has presented at international venues such as Cloud Expo 2013 West in North America.

Commercially, T-Cloud operates as a membership-based, non-profit research association rather than a product company; it does not publish revenue, pricing, or membership-fee data. Distribution of its "services" — knowledge sharing forums, project participation, and study group access — is through membership enrollment. Participants are drawn from Japanese research institutions, enterprise technology companies active in IoT and cloud (including automotive, home automation, and building management), and government/public-sector organizations involved in smart city and open data initiatives. The organization has held 54 general meetings by mid-2026, with a 55th meeting scheduled for June 2026 at the University of Tokyo.

Core offering

T-Cloud (Transparent Cloud-computing Consortium) is a Japan-based research consortium that studies how the linkage of 'devices' with 'cloud' systems changes computing models and creates new value through organic data processing. It runs collaborative research across three domains — device applications, large-scale data analytics (Big Data), and platforms — through projects (T-Village smart home, 車雲 smart car, smart meter, smart building) and study groups (security/privacy, large-scale data processing, framework/cloud, IEEE1888, business cases), and disseminates results via general meetings and conference participation. The consortium is led by Professor Hiroshi Esaki of the University of Tokyo and operates as a member-based, neutral organization since 2012.
