What Hide&Seek does

Hide&Seek (株式会社Hide&Seek, operating as ハイドアンドシーク) is a Fukuoka-headquartered, privately-held Japanese professional services firm founded in 2012 that provides integrated e-commerce and direct-to-consumer (D2C) support. Its core offering is one-stop EC mall operation agency work across Amazon, Rakuten, and Yahoo! Shopping — including listing optimization, anti-resale countermeasures, advertising, and CRM — complemented by D2C consulting (brand launches and existing-business turnaround) and web marketing support (advertising operations, LP/HP production, SEO). Documented outcomes include 21x maximum sales lift after one year for Rakuten/Yahoo clients, 80–90% resale elimination within three months, and 50%+ average repeat-customer ratios.

The company operates two proprietary technology assets layered on top of its agency services: Popee, a popup tool for LP/HP exit-intent capture and promotional displays, and EC Reviver, a SaaS that automatically recovers form abandonment and upsell abandonment to maximize EC sales. These tools, while not AI-driven, signal a directional productization of internal agency playbooks into recurring-revenue software. Hide&Seek generates revenue through custom-quoted professional services retainers and project fees across its three service pillars; pricing is not publicly disclosed and engagements are scoped via direct consultation through the company's website.

Hide&Seek's go-to-market is consultative and content-led: a categorized blog covering ECモール, 広告運用, SEO, CRM, and Instagram drives organic inbound, supplemented by webinars (including a co-hosted June 2026 webinar with Heart Beats on EC CPA optimization). Customer segments skew toward Japanese D2C brands in health, beauty, and consumer goods, with visible logos including Vitabrid C, CHURACOS, Bella Pelle, matera, コーピーエス, Beauminant, STELLA, tellas, and ファンファレ, and stated scale of 50+ Amazon clients and 10+ D2C launch engagements. The firm holds JAFIC Mark certification for personal information protection, supporting its affiliate/re-targeting work. Geographic scope is domestic Japan only.

Core offering

Hide&Seek is a Japanese professional services firm providing EC (e-commerce) mall operations agency services for Amazon, Rakuten, and Yahoo! Shopping, including listing optimization, advertising, CRM, and anti-resale countermeasures. The firm also offers D2C consulting for new brand launches and existing business turnarounds, plus web marketing support encompassing advertising operations, LP/HP production, and SEO. Two proprietary tools, Popee (popup tool) and EC Reviver (SaaS for automatic recovery of form/upsell abandonment), complement the agency's service offerings.

Product overview

Hide&Seek operates as a one-stop professional services firm specializing in web-based direct-to-consumer (D2C) sales. The company offers a portfolio of interrelated services centered on three pillars: (1) EC mall operations management (covering Amazon, Rakuten, and Yahoo! Shopping, including counterfeit prevention, listing optimization, and CRM), (2) D2C consulting (for brand launches and business turnarounds), and (3) Web marketing support (encompassing advertising operations, LP/HP production, and SEO). A secondary branded tool, popee, provides exit-intent popup functionality for client landing pages. The three core service lines are designed to work together as an integrated D2C support ecosystem, with EC operations and consulting informing marketing strategy and vice versa.

Direct peers

• CINC (Core Inc.): Japan-based digital marketing agency specializing in inbound marketing, SEO, and content-driven demand generation for B2B and B2C brands. Directly comparable in using content and SEO as the primary inbound engine, similar in scale to Hide&Seek.
• Repro: Japan-based marketing automation and conversion optimization platform with strong D2C / app-commerce tooling. Competes with Hide&Seek's Popee and EC Reviver layer by offering analytics-driven funnel optimization for the same Japanese D2C buyer.
• Kaizen Platform: Japanese CRO and LPO specialist serving many of the same enterprise and D2C brands Hide&Seek targets. Directly overlaps with Hide&Seek's LP/HP production and SEO service modules and competes for the same web conversion budget.

Broad incumbents

• Dentsu: Japan's largest advertising agency group with end-to-end digital, e-commerce, and CRM practices. A broad incumbent that competes with Hide&Seek at the upper end of the Japanese D2C and consumer brand advertising/CRM spend pool.
• Adways: Japanese digital marketing group with advertising operations, affiliate, and e-commerce enablement services. Comparable in being a multi-channel marketing services provider for D2C and e-commerce clients, but broader and larger scale than Hide&Seek.
• Septeni Holdings: Japan-listed digital advertising and e-commerce marketing group with overlapping capabilities in digital ad operations, D2C support, and CRM-style services. A larger incumbent offering a broader portfolio rather than Hide&Seek's specialized, one-stop EC mall + D2C focus.
• Digital Holdings: Japanese digital advertising and marketing group encompassing multiple agencies and ad-tech businesses. Overlaps with Hide&Seek on performance advertising, SEO, and digital marketing services for Japanese brands.
• Hakuhodo: Second-largest Japanese advertising agency network with significant digital, content, and e-commerce commerce capabilities. Competes for the same Japanese D2C brand budgets but at much larger scale and broader service scope.

Emerging players

• Wacul: Japan-based analytics and conversion optimization provider for e-commerce sites, with adjacent capabilities to Hide&Seek's LP/HP production and EC funnel optimization work. Smaller and more analytics-focused versus Hide&Seek's full-service agency model.

Regional players

• Heart Beats: Japanese e-commerce/D2C agency co-hosting webinars with Hide&Seek and operating in the same Japanese D2C consulting ecosystem. Comparable in offering EC consulting and digital marketing services to Japanese D2C brands.
