What Is the Oya Soichi Bunko: The Value of Japan's Largest Magazine Archive
Magazines serve as a mirror 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?
Founded 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 Soichi Bunko contains the history of "Japan's curiosity" spanning approximately 160 years.
The true value of the Oya Soichi Bunko lies not just in the number of books it holds. 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 were 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, one can understand the roots of its current management strategy and the challenges it faced at that time. By tracking the past activities of competitors, companies can also reaffirm their own 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 did the vast collection of magazine article information from the Oya Soichi Bunko become easily accessible through the corporate information and business card management app, mSonar? The background lies in a data partnership driven by the alignment of visions between uSonar and the Oya Soichi Bunko.
uSonar provides a variety 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 continued to record the "past" of companies through the medium of magazines. By partnering, the two organizations aim to connect the present and past of companies—which were previously fragmented—to enable a more three-dimensional understanding of customers. This shared sense of purpose led to this groundbreaking partnership.
Specifically, approximately 127,000 article titles related to companies, selected from the 7.65 million magazine article indices held by the Oya Soichi Bunko, have been integrated into the "Magazine Feature" of mSonar (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 corporate information page. This "valuable analog information," which previously required a trip to the library to access, can now be retrieved anytime, anywhere, right from a smartphone. This can be considered an unexpected fusion that challenges the conventional approach to business information gathering.

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 it is.
Generally, mSonar might be recognized as a type of "Business Card Management" or "Business Card App." It certainly possesses the basic functionality of scanning business cards to digitize and manage customer information. However, the essence of mSonar lies beyond that.
mSonar is not merely a tool for managing business card information; it is 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 becomes more than just contact details; it is linked to multifaceted information such as industry, company size, financial data, and even the latest news and industry reports.
With this partnership with the Oya Soichi Bunko, the time axis of a company's "past" has also 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. This can be described as 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 scenario, from daily sales activities to important management-level decision-making.
Business Card Management App "mSonar" Use Cases: 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 Changes the Quality of Conversation
Customer Success Representative A is preparing for a new client visit. While on the train, A takes out their smartphone and opens the client's company 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 'Maverick of the Industry'." Just from this article title, A felt they had touched upon a part of the company's DNA. At the beginning of the business meeting, A starts the conversation: "I understand your founding president was once called the 'Maverick of the Industry'." A did not miss the change in the client's expression at this remark.
Case 2: Closing the Distance Instantly with Small Talk Immediately After Exchanging Business Cards
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, which would not have been born from a simple business card exchange, was created.
Case 3: Overwhelming Persuasiveness Through Proposals with a Narrative
Imagine Sales Representative C is busy creating a proposal for an important competition. The core logic of the proposal is solid, but C wants 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 article 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 proposal 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 That Go Beyond Simple Information Transfer
Sales Representative D is handing over a client account to a younger 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, but the very "stories" that the company has woven. By passing on these stories, D renewed the belief that sales representatives can evolve from mere "account managers" into "partners" who understand the history of their clients.
Summary: The Evolution of the mSonar Business Card Management App is Shaping the Future of Sales
As we have explored, the integration between mSonar and the Oya Soichi Bunko library is more than just a functional addition. It provides a catalyst for evolving the very act of understanding customers in a business context into something deeper and more insightful.
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 clarity.
The untold history and philosophy of a company are things that can never be seen through web searches or the use of generative AI alone. Understanding these elements is the source of building strong relationships of trust with customers and creating truly valuable proposals. Through mSonar, now integrated with the Oya Soichi Bunko library, we will continue to support you in leading your business and the future of sales to a new stage.
