“Paper Strikes Back” Against Soaring Online Ads: Share & Subscription-Based Low-Cost Promotional Service 'Share Chirashi' to Exhibit at Japan's Largest Marketing Expo 'MarketingWeek'

Design-a Inc. (Headquarters: Hakata-ku, Fukuoka; CEO: Takayuki Shikou, hereinafter 'Design-a'), operator of the shared and subscription-based direct mail service 'Share Chirashi,' announces its participation in 'MarketingWeek (commonly known as MaS),' Japan's largest advertising and marketing exhibition, to be held at Tokyo Big Sight for three days starting June 24, 2026.

At its booth, the company will not only unveil the latest case studies of its B2C 'Share Chirashi' service—now with over 1,200 cumulative contracts—and introduce the innovative 'Community Contribution Section' for the first time, but also launch pre-registration and detailed announcements for its new B2B-focused service, the shared direct mail 'Share Envelope,' set to begin operations in August 2026.

■ Background of Exhibition: Overcoming Challenges in Both Online and Offline Marketing

Currently, in the marketing market, the cost per acquisition (CPA) of online advertising is soaring, and intense competition has turned many sectors into 'red oceans,' posing a major challenge for businesses. At the same time, traditional offline media such as newspaper inserts and standalone direct mail (DM) are becoming less effective due to declining newspaper subscription rates and rising costs.

In response, Design-a has proposed a 'shared promotional' model, where multiple companies share distribution and postage costs, enabling direct, high-impact outreach at an overwhelmingly low cost. At this exhibition booth (Startup Gate), the company will present the latest trends and optimal solutions for area marketing in both B2C and B2B domains.

■ Key Booth Highlights and Features of the New 'Share Envelope' Service

1. Pre-Registration Launch of B2B-Focused 'Share Envelope' (Starting August)

Applying expertise gained in the B2C sector, Design-a will introduce a new service that shares postage costs among multiple companies. The company will provide detailed information at the exhibition booth and begin accepting pre-registrations. Adoption has already been confirmed by major CATV (cable TV) operators and franchise headquarters expanding nationwide.

The Shock of 90 Yen per Unit (Excl. Tax):

A single flat rate includes list extraction, postage, A4-sized promotional material printing, and even 'one-sided design creation.'

Industry-Segmented Mailing:

Targeted mailing by industry, such as 'real estate businesses,' 'clinics,' 'beauty salons,' and 'restaurants,' enabling precise outreach.

Small-Scale Start from 1,000 Units:

Minimum order of 1,000 units allows low-risk test marketing.

High Open Rate:

Multiple companies' promotional materials are enclosed together in one envelope (co-mailing), increasing the likelihood of being read by decision-makers compared to standalone DM.

2. Live Display of 'Share Chirashi' (Over 1 Million Units Monthly) and the Innovative 'Community Contribution Section'

Physical samples of 'Share Chirashi,' which reaches core commercial areas reliably and densely at one-third the cost of standalone distribution, will be available. Additionally, visitors can preview the latest flyers incorporating the 'Community Contribution Section,' a new social contribution initiative that will launch in August 2026, offering free space for information on children's cafeterias and cat adoption events.

3. Special Proposal Schemes for Franchise Headquarters and Advertising Agencies

The company will present concrete collaboration and implementation case studies tailored for franchise headquarters seeking promotional tools that protect franchisee profits, and for advertising agencies looking for new client engagement hooks (foot-in-the-door products).
