What It Is

株式会社コミュニケーション科学研究所（Communication Science Institute Inc.） is a market research and data analytics consulting firm based in Shinjuku, Tokyo, Japan. Founded in 1977, the company positions itself around “digital analytics × field research,” combining digital data from SNS, the Web, CRM, and other sources with first-hand information such as user interviews, on-site observation, and surveys. Its work is used for market assessment, marketing improvement, brand building, and estimating economic ripple effects.

Core Capabilities and Data Sources

Its services fall into four main areas: data analytics, market research/marketing research, brand strategy, and economic ripple-effect analysis. Data analytics covers Web and SNS behavior logs, CRM purchase histories, text mining, and statistical forecasting models. Market research includes online surveys, interviews, field research, competitor analysis, and desk research on the market environment. Brand services cover awareness and image diagnostics, USP and brand story development, and internal branding. Economic ripple-effect analysis uses input-output analysis, combined with field data such as visitor questionnaires and interviews with nearby stores. The official website repeatedly emphasizes that it does not merely provide numerical conclusions, but also explains the psychology and behavioral reasons behind user actions.

Pricing, Platforms, and Support

The official website does not disclose pricing, plans, delivery timelines, or free trial information; in practice, it is likely quoted on a project-by-project consulting basis. In terms of supported platforms, it can only be confirmed that the company handles Web, SNS, CRM, survey, public statistics, and offline research data. It does not state whether it can integrate with GA4, advertising platforms, CRM systems, or BI tools. The company provides a phone number, fax number, and Tokyo office address, but there is no visible information about online chat support, cross-border services, or Chinese-language support.

Pros and Cons

Its strengths lie in a relatively complete service chain: it can handle marketing data analysis, qualitative research, brand strategy, and economic impact assessment. This makes it valuable for organizations that need to connect “what happened” with “why it happened.” Its membership in Japanese market research and public relations-related associations also adds a degree of professional credibility. The drawbacks are that the website lacks detailed case studies, pricing, sample sizes, tool stack information, and in-depth methodology explanations. The disclosed employee count is 5, so its execution capacity for large, multi-region projects should be confirmed separately.

Best Fit and Access from China

It is better suited to companies, local governments, and project owners operating in the Japanese market that need consumer insights, advertising and website improvement, repeat purchase/LTV enhancement, brand repositioning, or economic impact evaluation for events and public projects. Access from China cannot be determined from the available website content alone, and payment methods are not disclosed. If targeting the Chinese market, it is advisable to also compare local Chinese market research firms and brand consulting firms, or to use GA4, social listening, and CRM analytics tools together with local consultants for execution.
