About Us

Who we are | SE Design

Our 30 years of knowledge and experience as a marketing partner of major global businesses

SE Design has supported the marketing efforts of many tech enterprises—including Microsoft Japan and SAP—since PCs gained popularity in the 1980s. We leverage the knowledge of our predecessor Shoeisha, a publisher specializing in IT and marketing media, to deliver expert content creation and editing skills honed in the publishing industry.

Based on this experience and talent, our marketing knowledge, skills, and networks to solve business challenges, we deliver a comprehensive range of online and offline media strategies to support your marketing initiatives.

Dedicated teams to solve your challenges

SE Design has dedicated teams in place to assist you—a Sales Support Team to offer direct advice and a Production Support Team to plan, create, and market your content.

Because these dedicated teams understand your unique challenges and needs, they propose plans and ideas to solve your issues, then bring your goals to fruition with our extensive partner network.

We offer and support powerful B2C and B2B marketing plans.

As the objectives of marketing promotions are different between B2C and B2B, so the actions required to put your strategies to work vary respectively.

We propose the best marketing measures and tools for you and your targets based on our proven track record in producing printed materials and web content, promotions, and event management in both B2B and B2C fields.

For X-Tech (Cross-Technology) Marketing
SE Design is committed to the growth of X-tech market with responsive marketing approaches


The ultimate goal of the entire marketing industry in the post-COVID era should be to create an "information society" in the truest sense of the phrase. Although the term informatization has become more familiar as technology has evolved over the past 50 years, Japan's use of informatization to only pursue work efficiency indicates a superficial understanding of the word.

Genuine informatization makes information technology effective by using it to identify problems in business models and present groundbreaking solutions. Today’s digital transformation fulfills the original intent of informatization by maximizing the effectiveness of information technology in an open data climate.

Since the dawn of PC civilization in Japan, SE Design has been working with enterprises such as Microsoft Japan and the Japanese arms of other global IT companies driving the worldwide market. Using our expert knowledge of the Japanese market, we have planned, produced content for, and managed corporate branding, marketing, seminars and events for these companies based on their marketing and communication strategies.

However, the IT business landscape around the Internet has changed over the years and is now expanding with a few platform-based giants dominating the global market.

New businesses are being rebuilt in all verticals, which will fundamentally reshape marketing ideologies from sales floors to boardrooms. The popularity of webinars is one example of changes in marketing mindsets, but the cross-tech era would demand more structural disruption.

Our focus is on reforming frameworks needed as the online environment—which was once a feeder in the business process—becomes the definitive playing field for communication and decision-making.

For example, marketing departments, once positioned to support sales, are now much more closely involved in final decision making for customers through activities such as inside sales. Face-to-face sales will be limited to the final step of the sales process or the entire process will be completed online, so marketing automation (MA) is a must in ensuring online marketing.

The structural disruption enabled by digital transformation in marketing will be the key to business sustainability in the future. We therefore aim to support companies in emerging cross-tech business environments with our proven ability to bring the marketing solutions to life.

We support our partners by developing new marketing measures based on the true meaning of informatization. Keeping our eyes on the future, SE Design is delivering marketing solutions to visionary cross-tech companies adapting to the changing environments in the hope of further growth of the industry and ourselves as well.
