What Is the Oya Soichi Bunko: The Value of Japan's Largest Magazine Archive
Magazines are like mirrors reflecting the curiosity of the people who lived in their respective eras. Past feature articles and interviews are packed with "living information" that cannot be found in modern digital content, such as events that served as turning points for companies, the philosophies of business leaders, and little-known evaluations within industries.
Have you ever heard of the Oya Soichi Bunko?
Established by the journalist Soichi Oya, who was active before and after the war, it is Japan's first library specializing in magazines and is truly worthy of being called a "treasure trove of magazines." Its collection is overwhelming, housing over 800,000 volumes across approximately 13,600 titles, starting from the "Seiyo Zasshi" (Western Magazine) published in the third year of the Keio era (1867) to the present day. This means that the Oya Bunko contains the "history of Japanese curiosity" spanning approximately 160 years.
The true value of the Oya Soichi Bunko lies not just in the number of books in its collection. What is particularly noteworthy is the existence of a vast "magazine article index" containing 7.65 million entries. This is a database that comprehensively covers which articles are published in which issues of which magazines, making it possible to instantly search for past articles on specific themes or companies. It is precisely because of this index that professionals such as researchers, editors, and writers have relied on the Oya Soichi Bunko as a highly reliable source of information.
In the business world, the value of this data is immeasurable. For example, by reading a feature article about a company from 30 years ago, you can understand the roots of its current management strategy and the challenges it faced at that time. By tracking the past trends of competitors, you can also reaffirm your own company's positioning. Until now, such valuable data was known only to a select group of experts. However, with the official partnership between uSonar and the Oya Soichi Bunko in 2023, those doors have been opened to sales teams and the broader business world.
Data Integration Between mSonar and the Oya Soichi Bunko: The Fusion of Analog and Digital
So, how has the vast magazine article information of the Oya Soichi Bunko become easily accessible through the corporate information and business card management app mSonar? The background lies in a data integration driven by the alignment of visions between uSonar and the Oya Soichi Bunko.
uSonar provides a diverse range of information that visualizes the "present" of companies, based on the "LBC," a corporate database covering 12.5 million locations. Meanwhile, the Oya Soichi Bunko has continuously recorded the "past" of companies through the medium of magazines. By collaborating, we aim to connect the previously fragmented present and past of companies, enabling a more three-dimensional understanding of customers. This shared sense of purpose has made this groundbreaking partnership a reality.
Specifically, approximately 127,000 article titles related to companies have been integrated into the "Magazine Feature" of mSonar from the 7.65 million magazine article indices held by the Oya Soichi Bunko (as of February 2026). As a result, mSonar users can now view a list of up to 200 past magazine article titles related to a company with a single tap from the company information page. This "valuable analog information," which previously could only be seen by visiting a library, can now be accessed anytime, anywhere, from a smartphone. This is surely an unexpected fusion that challenges the conventional approach to information gathering in business.

What Is the Business Card Management App "mSonar"?: A "Customer Understanding Platform" That Goes Beyond Simple Business Card Management
For those hearing about "mSonar" for the first time, let us summarize what mSonar is.
Generally, mSonar might be recognized as a type of "Business Card Management" or "Business Card App." It certainly possesses the basic functions of scanning business cards to digitize and manage customer information. However, that is not the essence of mSonar.
mSonar is not merely a tool for managing business card information, but a "platform for deepening customer understanding." At its core is the "LBC," a corporate database covering 12.5 million locations across Japan. By integrating with this LBC, the business card information imported into mSonar is linked not just to contact details, but to multifaceted information such as industry, company size, financial data, and even the latest news and industry reports.
Furthermore, with this collaboration with the Oya Soichi Bunko, the time axis of a company's "past" has been added. While tracking the "present" of a company through the latest news, you can now interpret the "context" of that company through past magazine articles. This allows the profile of a customer company to emerge three-dimensionally—not just as a point, but as a line, and even as a plane. We believe this is an experience that exceeds the value provided by conventional Business Card Management tools.
Please view mSonar as a tool that supports "Customer Understanding" through magazine titles in every business scene, from daily sales activities to important management-level decision-making.
Usage Scenes for the Business Card Management App "mSonar": Transforming the Sales Frontline
So, how can the integration between mSonar and the Oya Soichi Bunko library be utilized in actual business scenarios? Here, we introduce four use cases in a story format, set against the daily lives of sales representatives.
Case 1: Three-Minute Research Before an Initial Visit Transforms the Quality of Conversation
Customer Success Representative A is preparing for a new client visit. While on the train, A takes out a smartphone and opens the client company's page in mSonar. After checking the basic information, A taps the "Magazine" tab. There, a list of titles from feature articles published in industry journals 20 years ago appears. "The Challenge of the Founding President, Once Called the 'Enfant Terrible of the Industry'." Just from this article title, A felt a glimpse into the company's DNA. At the beginning of the business meeting, A starts by saying, "I understand your founding president was once called the 'Enfant Terrible of the Industry'." A did not miss the change in the client's expression, showing that their perception had shifted.
Case 2: Small Talk Immediately After Exchanging Business Cards Closes the Distance Instantly
At a large-scale exhibition venue, Marketing Representative B is exchanging business cards with many attendees. Immediately after exchanging cards with a representative from a certain company, B quickly checks the company information on mSonar. B discovers that just a few years ago, the company was featured in a business magazine as a "Leading Company in Work-Style Reform." B says, "Your company was featured in '△△' magazine a few years ago for your unique work-style reform initiatives, right?" The client, surprised but pleased by the unexpected comment, begins to speak animatedly about their company's efforts. It was a moment where empathy was born that would not have been possible through a simple business card exchange.
Case 3: Overwhelming Persuasiveness Through Proposals with a Narrative
Imagine Sales Representative C is busy creating a proposal for an important competition. While the core logic of the proposal is solid, C feels the need for one more push—a story that will move the client's heart. When C searches for past magazine articles about the client company on mSonar, C finds an interview title from 10 years ago, spoken by the current president right after taking office: "In 10 Years, We Will Be the Leading Company in This Industry." Sales Representative C quotes the president's words and powerfully states at the beginning of the proposal that this current offer is exactly what will realize the vision from 10 years ago. The story connecting the past to the present brought overwhelming persuasiveness to the proposal and captured the hearts of the executives.
Case 4: Internal Sharing and Handovers Become More Than Just Information Transfer
Sales Representative D is handing over a client account to a young successor. Simply passing on SFA records does not convey the nuances of the relationship with the client. While showing the mSonar screen, D speaks to the successor: "This company had these struggles at its founding, which led to where they are today." The magazine article titles accumulated in mSonar are not just information; they are the very "stories" the company has woven. By passing on these stories, D renewed the belief that sales can evolve from being mere "representatives" to "partners" who understand the history of their clients.
Summary: The Evolution of the Business Card Management App "mSonar" Creates the Future of Sales
The integration between mSonar and the Oya Soichi Bunko is far more than a simple functional addition. It provides a catalyst for evolving the very act of understanding customers in a business context into something deeper and more enriched.
While many Business Card Management tools and Business Card Apps adopted by companies focus primarily on operational efficiency, mSonar provides a more fundamental value: the deepening of customer understanding. By combining the efficiency and comprehensiveness of digital data with the vivid and rich context and narratives inherent in analog information, companies can view their clients with a new level of resolution.
The untold history and philosophy of a company can never be uncovered through web searches or generative AI alone. This understanding is the source of building strong, trusting relationships with customers and generating truly valuable proposals. Through mSonar, now integrated with the Oya Soichi Bunko, we will support you in leading your business and the future of sales to a new stage.
