How Japan’s largest transit media owner centralised operations and reduced manual work by 85%

Key Takeaways

• Centralizing operations helped Jeki manage over 36,000+ screens seamlessly across Japan.
• Automating workflows reduced 85% of repetitive admin tasks, freeing teams to focus on revenue.
• Real-time campaign activations allowed jeki to reach 17.3 million weekly commuters faster.
• Dynamic rate cards ensured consistent pricing, improving advertiser trust and repeat bookings.

Keeping Pace with a Growing Network

Jeki, one of Japan’s largest transit and outdoor media operators, was rapidly expanding its network of digital screens across busy train stations and shopping hubs.

This growth brought exciting opportunities with advertisers but also exposed operational inefficiencies. Manual updates, inconsistent rate cards, and delayed campaign activations began straining internal teams and fell short of the speed and flexibility that brands expected. 

To scale sustainability, jeki needed a single, centralised platform to simplify operations, unify data, and streamline campaign planning activations,

Who is Jeki? A Leading Force in Japan’s Transit Media

East Japan Marketing & Communications (Jeki) operates a vast network of digital screens located in Japan’s busiest train stations and retail hubs. Their media inventory reaches over 17 million urban commuters weekly, making them one of the country’s most influential OOH media owners.

Despite its market presence, Jeki relied heavily on manual processes that were becoming unsustainable as their inventory scaled.

When Growth Becomes a Challenge

As its network grew, Jeki faced three hurdles:

• Repetitive admin work: Constant updates to locations and pricing drained time.
• Fragmented planning tools: Disconnected systems caused delays for advertisers.
• Slower campaign activations: Brands couldn’t launch as quickly as needed.

If left unresolved, these bottlenecks would lead to slower service, increased costs, and strained client relationships.

The Solution – One Platform, Seamless Operations

Jeki partnered with Moving Walls to implement a tailored system that replaced fragmented processes with a centralized, automated workflow.

Key features included:

• Branded infra-URLs for secure, simplified team and partner access.
• Dynamic rate cards to keep pricing consistent and easy to manage.
• Bulk location tools to remove repetitive data entry.
• Guided onboarding and training for smooth adoption.

Moving Walls’ solution enabled centralized planning, automation of repetitive tasks, and real-time campaign activation across more than 36,000 screens. With everything unified, Jeki could activate campaigns quickly, keep pricing transparent, and manage its growing network with less effort.

The Rollout – A Phased Transition

To minimise disruption, the transition followed three steps:

Phase 1: Setup & Training

Jeki’s teams were onboarded and guided through initial platform configuration.

Phase 2: System Integration

Manual workflows were replaced with Moving Wall’s OOH automation and centralized access.

Phase 3: Optimization and Scale

Moving Wall’s platform became the single source of truth for inventory, pricing, and campaign activations.

The Results – A More Agile Jeki

By adopting Moving Walls, Jeki transformed how it manages its 36,000+ transit screens which account for 70% of Japan’s urban OOH inventory. With automation and a single, centralized hub, Jeki can now:

• Engage 17.3 million weekly train passengers across Tokyo and other metro hubs through faster, more flexible campaigns.
• Eliminate 85% of repetitive admin work, allowing teams to focus on building advertiser relationships and driving revenue.
• Activate campaigns in real time, meeting the speed and precision advertisers expect.
• Offer consistent reporting and transparent pricing, reinforcing trust and long-term partnerships.
