Company profile

researched Aug 2026

Life Log Technology K.K. operates Calomeal (γ‚«γƒ­γƒŸγƒ«), an AI-equipped health management application built around recording daily life logs β€” principally meals β€” and using machine learning to support user decision-making. The company frames its purpose around extending healthy lifespan in Japan, citing the burden of an ageing society, shrinking working population and social-security costs, and noting that lifestyle-related diseases underlying Japan's three major causes of death are driven by diet, sleep, smoking and exercise.

Around the consumer app the company has built a family of B2B products: Calomeal Advice (γ‚«γƒ­γƒŸγƒ«γ‚’γƒ‰γƒγ‚€γ‚Ή), a meal-logging and advisory tool adopted by personal gyms, clinics, beauty and esthetic salons, pharmacies, integrative-medicine clinics, nutritionists, universities and corporate sports teams; Calomeal Health Guidance (γ‚«γƒ­γƒŸγƒ«δΏε₯ζŒ‡ε°Ž), a service for Japan's specified health guidance programmes with interview booking and progress management features; and Calomeal WebView, an embeddable module that lets third-party apps add meal-recording functionality. The company also packages the resulting eating-behaviour data for research, product development and marketing use, including analyses combining consumption data with generative AI and the fusion of vital-sign data with dietary data for digital health businesses.

Business model

Life Log Technology combines a consumer health-management app with business-facing subscriptions and integrations: Calomeal Advice for practitioners and organisations delivering dietary guidance, Calomeal Health Guidance for specified health guidance providers, Calomeal WebView for embedding meal logging into third-party applications, and data services derived from accumulated eating records for research, product development and marketing [0].

Traction

The website publishes a continuous stream of Calomeal Advice adoption notices between 2025 and 2026 across fitness, healthcare, beauty, pharmacy, sports, manufacturing and university customers, typically single sites with cohorts ranging from one to several hundred people. Other traction signals include municipal programmes in Tsukuba and Sendai, a WebView integration with Pixela, a joint monitor study with Meiji's SAVAS Weight Down in which over 90% of participants reported increased confidence in continuing dieting, co-development of a "healthy onigiri" product with rice-ball chain Bontabonta, adoption of Calomeal record data by a Tokyo University of Science seminar/research group, and referral placement on the online-medicine platform Levaclinic [0].

Latest developments

During 2026 the company announced a Tsukuba City demonstration project applying PHR data to product recommendations and dietary improvement for lifestyle-disease prevention and healthy-lifespan extension (2026-08), added barcode scanning to Calomeal WebView (2026-07), co-developed a health onigiri product with Bontabonta following survey research (2026-07), published joint monitor results with Meiji SAVAS Weight Down (2026-07), launched an AI persona experience with fitness instructor Marina Takewaki (2026-05), began providing WebView meal recording to Pixela (2026-05), and had Calomeal record data adopted for research use by Tokyo University of Science's Faculty of Advanced Engineering (2026-04) [0].
