In 1986 he joined Sharp Corporation, where he worked in sales, sales planning, liaison (corporate planning and IR), and public relations.
While in public relations, from 1996 to 2006, he made major contributions to hit products such as AQUOS and Healthio, as well as enhancing their brand image.

Managing Director of M-Cube, Inc.
Masami Fujino
(Masami Yamawaki)
Masami graduated from the Department of English and American Literature in the Faculty of Letters, Keio University. She is a Certified Member Analyst (CMA) of the Securities Analysts’ Association of Japan.
Masami has 20 years’ experience researching and analysing Japanese equities in non-Japanese securities companies. She has covered companies in the electronics, telecoms and small and medium-sized company sectors at Swiss Bank Securities (currently UBS Securities), and Jardine Fleming Securities (currently JP Morgan), and undertaken corporate research at Nikko Citigroup Global Markets, supporting investment by domestic and foreign institutional investors in Japanese listed companies. She believes in discovering the value of companies without being constrained by conventional ideas, and communicating this to institutional investors both inside and outside Japan. Masami has consistently appeared in Nikkei Analyst and Institutional Investor rankings. She has also worked as a buy-side analyst at the US hedge fund Indus Capital, enabling her to benefit from both sell-side and buy-side perspectives.
Since 2015, Masami has been involved in creating roadshow materials for companies engaged in IPOs, equity stories for listed companies, medium-term management plans, and financial results briefing materials for a major IR company. Masami believes that maintaining close relations with a company, and having frequent discussions, enable that company’s unique strengths to be discovered, making it possible to produce research materials that take into account investors’ thought processes and priorities. Investors can better understand companies when they are given this kind of assistance, which makes it possible to engage in active dialogue. She is pleased to be able to participate in the process of improving the competitiveness of Japanese companies.
Currently, while continuing to support the enhancement of corporate value as an IR consultant, she oversees the company's real estate and web media divisions. Leveraging the objective analytical skills cultivated through years of financial and corporate research, she drives business operations from a multifaceted perspective, which includes heading a real estate media platform dedicated to the accurate dissemination of information.
Our Services
PR Support
Any start-up company wants its technology or product to become widely known, and commercialized, as soon as possible – but they don't always know how to do this.
M-cube has more than 10 years’ experience in providing PR support to start-up companies in the electronics, IT, robotics, and advanced technology fields.
As a consultancy, we will outline the basics of PR, such as the difference between public relations and advertising.
We will also develop a PR strategy and a plan for rapid media exposure.
We can prepare press releases and other materials for the media, as well as contacting media representatives, on an outsourced or consulting basis.
Companies that were start-ups only a few years ago have now become listed, with products and services that are widely known as a result of PR.
What is the difference between publicity (advertising) and public relations?
Start-up companies usually have only a very small budget they can devote to advertising. However, media articles are written by the media themselves, on subjects they consider valuable to their readers. The important thing is understanding how this "value" can be conveyed.
The key to success in public relations is a detailed strategy and plan, and a dynamic approach, to conveying this value. We will support you by establishing a series of workflows, from strategy and planning to creating PR stories and liaising with the relevant media.
There are many examples of start-ups that have built up their corporate and product brands by steadily building up long-term strategies. To achieve this, key factors are the amount of exposure, the consistency of the message, and the continuity of exposure.
We provide PR support not only in Japan but also via overseas media, and in providing support for presence at overseas exhibitions such as CES in the US. For overseas exhibitions we have worked with a PR agency in the U.S.; one of our startup clients was featured on the No. 1 Tech Web in the U.S.
IR Support
We provide various types of IR support to meet the needs of companies. In particular, we excel in creating equity stories and arranging and supporting online meetings with overseas investors that match the company's needs.
To understand and invest in a company, investors need more than a corporate profile and the financial results. A company needs to create an equity story, explain itself to investors on the basis of that story, and take part in a dialogue (“engagement”).
An equity story is a description of a company's special characteristics using terms and expressions that investors can understand. The story may cover the company’s unique strengths; its business model; its profit structure; the market in which it operates and its position in that market; any barriers to entry into that market; the company’s strategy, growth potential, etc.
Our long experience that encompasses talking to and analyzing thousands of companies, and talking to thousands of domestic and foreign investors, means that we can create easily understandable, persuasive equity stories for communicating a company's strengths and growth potential.
Based on an equity story, we can prepare various kinds of presentation material – corporate, financial results, medium-term plans etc. – in both Japanese and English.
We can arrange online meetings with overseas investors who match your company's needs, using our network of professionals in North America, Europe, the Middle East, Asia, and Japan who have built trusting relationships with institutional investors over many years.
We can also provide interpretation, translation of materials, anticipated potential questions, rehearsal of the meeting, feedback, etc. as required.
Real Estate Rental Management and Digital Content Business
