THINK STONE (シンクストーン), based in Osaka, develops opportunities for Japanese energy-saving solutions in Japan and ASEAN. It works with local partners to reach manufacturing and service-sector customers.

Its areas of interest include HVAC energy saving, insulation and heat-shield coatings, IoT and automation, energy monitoring, and energy generation. Implementation emphasizes measurement, visualization of results, and on-site trials.

Partnership interests in Vietnam: energy-saving and energy-generation companies, factory automation providers, HVAC and M&E contractors, window/glazing suppliers, and specialist construction contractors for joint customer development, implementation, and ZEB-related engineering cooperation.

Equipment supply, trial arrangements, warranties, and responsibilities must be agreed for each project. The mission profile does not provide guaranteed savings or payback periods.
