ADMAIL

What ADMAIL does

ADMAIL (株式会社アド・メール) is a privately held Japanese Kabushiki Kaisha incorporated on August 9, 1975 and headquartered at 4-5-12 Sarayoshi-nishi, Ibaraki, Osaka. The company provides an integrated suite of direct-mail and marketing services, with its core offering being mailing services (メーリングサービス) for the distribution of direct mail that involves handling entrusted personal information. Around this core, ADMAIL bundles sales promotion, event planning and operation, distribution and fulfillment processing, custom system development, and business produce/consulting, supplemented by printing of pamphlets, brochures, and flyers. The company operates as a micro-enterprise with 1–10 employees, registered capital of JPY 10 million, and a single headquarters location serving the Kansai region of Japan.

The business model is transaction-fee / project-based: clients engage ADMAIL directly via phone and inquiry to scope mailing, promotion, event, or fulfillment projects, and pricing is not publicly disclosed. ADMAIL's primary customer segment is Japanese domestic businesses needing direct-mail distribution, sales-promotion campaign execution, event management, or integrated BPO-style fulfillment. All personal data handled in the DM workflow is governed by a certified Personal Information Protection Management System under JIS Q 15001, for which the company has held the JIPDEC Privacy Mark continuously since October 2005, most recently renewed to the 2023 standard in November 2025.

ADMAIL is owner-operated, with Representative Director Ishiguro Hiroyuki (石黒 裕之) serving as CEO and also acting as the personal information protection manager and primary point of contact. There are no disclosed subsidiaries, no venture or private equity investors, no M&A history, no public partnerships, and no digital or AI-driven technology stack — the company's competitive positioning rests on its longevity, integrated service menu, and certified privacy/compliance posture rather than on proprietary technology or scale.
