ONE's Data is a marketing-focused 1st Party DMP / Private DMP provided by 株式会社オプト. Delivered as an ASP service, it is designed to centrally collect, store, and integrate behavioral and performance data scattered across a company’s Web, App, offline membership information, purchase history, POS, and core business systems, then make that data available for analysis, reporting, ad delivery, and marketing decision-making.
The product focuses on solving data-silo problems: first collecting data from online and offline touchpoints, then integrating it into a meaningful single source of data, and finally using it for customer understanding and growth initiatives. The product page explicitly mentions cross-channel analysis, visualization of actual conversions and media conversion rates, exclusion of existing users from advertising, lookalike expansion based on loyal users, assessment of content completion rates and clicks, and prediction of LTV/CV based on behavioral logs and purchase data. Its admin interface allows non-engineers to extract data, and specified-field reports can be downloaded with one click.
No specific pricing is publicly disclosed, but the model is distinctive: data storage is free during the accumulation period, and billing begins when the data is actually used. The terms state that fees are agreed via application forms or similar documents, settled at the end of each month, and paid by bank transfer to a designated account by the end of the following month. The minimum usage period is 3 months. The service is not just a tool delivery: it also includes tool selection, implementation design, setup, operation, consulting, and support from dedicated analysts, with assistance for KPI definition and analysis.
Its strengths are a clear positioning and a design built around a first-party data marketing loop, making it suitable for companies that already have multi-channel customer touchpoints. The accompanying analytics and implementation support also reduce the risk of a DMP becoming a place where data is “stored but not used.” The downsides are that public information lacks specific pricing, integration lists, processing scale, and technical specifications. Customers still need to handle some environment setup themselves, such as inserting specified strings into website HTML. The terms are also cautious regarding personal information and data subject to cross-border regulations, so companies need to verify compliance around notices, consent, and privacy policies on their own.
ONE's Data is better suited to marketing and data teams at mid-to-large enterprises targeting the Japanese market or working with Japanese service providers, as well as organizations that need to unify advertising, CRM, App, and offline transaction data for ad optimization and reporting analysis. Access from China is not disclosed in the available text. Payment is mainly via Japanese bank transfer, which may create uncertainty for Chinese companies around network access, contracts, and payment processes. For localized alternatives, consider 神策数据, GrowingIO, or 诸葛io; for international alternatives, look at GA4, Adobe Experience Platform, Treasure Data, Tealium, or Segment.
