Japan Marketing Manager

We are looking for a Growth Marketing Manager to lead the digital growth function for a well-known consumer entertainment destination in Japan, with a focus on new customer acquisition.

In this role, you will be managing a small internal team and external agency partners across four digital growth channels: paid media, SEO, email marketing, and affiliates. You will have the depth and ownership of an in-house lead, backed by an experienced growth agency team. This is a high-visibility, high-impact role for someone who takes real ownership of outcomes and is motivated by turning performance around.

This is a full-time hybrid role requiring some onsite work, and is expected to run for at least 12 months.

Responsibilities

• Own and manage four digital growth channels: paid media, SEO, email marketing, and affiliates — setting strategy, managing agency and vendor execution, and owning performance reporting end-to-end
• Manage and develop a small internal team, providing clear direction, accountability, and day-to-day support
• Oversee and hold accountable all external agency and vendor partners — paid media agency, SEO agency, email platform vendor, and affiliate partners — ensuring all partners are briefed clearly and working against measurable KPIs
• Lead the channel audit in Month 1 — documenting current performance, identifying gaps, and producing a priority-ranked action plan
• Develop and deliver a phased CPA improvement roadmap based on actual performance data, with clear milestones and testing hypotheses
• Collaborate closely with the Brand Marketing team on the creative briefing process — ensuring growth channel requirements are built into briefs from the start, not adapted after the fact
• Brief and manage the development of audience-specific landing pages, and drive CRO improvements on key conversion pages in partnership with the web team
• Produce weekly and monthly performance reports that explain what happened, why it happened, and what should change next
• Represent the growth function in senior business reviews and key stakeholder meetings

Required Experience

• Japanese native speaker, and business-level English fluency required
• 5+ years of hands-on experience managing digital growth channels — paid media (Meta and Google required), SEO, email, and/or affiliates
• Proven experience managing or working within a consumer brand, entertainment, hospitality, retail, or high-volume B2C environment
• Experience managing external agencies and vendors — briefing, performance management, and accountability
• Strong analytical skills with the ability to derive clear, actionable insights from performance data across multiple channels
• Experience managing or mentoring at least one team member
• Comfortable presenting to and working with senior client stakeholders
• Based in Tokyo or willing to relocate. On-site presence required in the first few months during onboarding

Job Type: Full-time for 12 months

Work Setup: Hybrid remote and on-site

Location: Japan
