What MASH does

MASH Corporation (株式会社マッシュ) is a Japan-based event production and advertising company founded in 1981, headquartered in Osaka with a regional office in Tokyo. The firm operates as a wholly-owned subsidiary of Asahi Broadcasting Group Holdings (ABC Group) since July 1, 2022, following a capital and business alliance agreement signed in April 2019. MASH provides end-to-end event production services spanning 10+ business categories including expositions, MICE, regional revitalization, online events, sales promotion, PR, sports/festival events, cultural events, facility operations, and character management, executing an average of 100+ event projects annually for government ministries, local governments, corporations, and cultural/medical organizations.

The company's technology stack combines digital and analog communication capabilities including CG/3DCG production, VR content creation, AI-powered simultaneous interpretation (delivered via a certified partnership with Pocketalk Co., Ltd.), GPS-based voice touring applications, and virtual conference platforms. MASH has built a portfolio of proprietary content IPs centered on the Nazo Shiro (historical real mystery game) series deployed at 20+ castles nationwide, the Kiku Tabi voice touring app, and the Yoshimaho infant-experience anime co-developed with ABC Frontier, DLE, and Hello Inc. The firm also co-developed the EVENT CARBON SIMULATOR, an industry-standard carbon calculator created with a 15-company JACE working group.

MASH's business model rests on three revenue streams: (1) project-based professional services fees for B2B event production to corporate, government, and institutional clients, with quote-driven pricing for most engagements and disclosed unit pricing of ¥1,200 advance / ¥1,500 same-day for Nazo Shiro consumer tickets, (2) original content licensing and merchandise revenue from proprietary IPs including app sales and character licensing, and (3) sales-agent distribution of the FUROSHIKI 99% recycled-material garbage bag sustainable product line. The company sells primarily through direct B2B enterprise field sales, with consumer-facing events distributed via travel agency partners (Club Tourism, Kintetsu railways) and the eplus ticketing platform. MASH holds ISO/IEC 27001 ISMS certification, multiple Osaka Prefecture business licenses, and a worker dispatch license, credentials that support its government and large-corporate procurement positioning.
