Moving Walls to Launch Outdoor Advertising Technology Platform in Japan.

Moving Walls, a global advertising technology company with roots in Singapore, has announced a partnership with JR East Marketing & Communications Inc. (jeki) to launch a technology platform that will automate all Out-of-Home (OOH) advertising across Japan.

Moving Walls’ technology uniquely automates all OOH media processes. The company brings years of experience in deploying white-labelled enterprise software on private cloud environments to maintain privacy. The company has a strong presence across Southeast Asia and India and has recently expanded into Subsaharan Africa and Latin America through local partnerships.

The platform, named MASTRUM, is an impression-based digital OOH advertising platform that provides ad space trading, ad serving, and programmatic DOOH advertising to meet domestic and international demand. This will enable highly efficient, high-value-added buying of digital signage and other types of OOH advertising across Japan.

Japan’s OOH advertising market is already the world’s third largest in terms of estimated spending. With this launch, jeki plans to expand the scope of media they handle to include other railways and outdoor media.

Ryoji Akaishi, President and Representative Director of East Japan Planning Inc. said, “We selected Moving Walls out of several leading ad serving platform vendors, as our ideal technology partner to create the largest marketplace for all types of OOH. By customising Moving Walls’ platform, jeki will be able to offer new services based on its long-accumulated expertise in transportation advertising and its unique perspective. We aim to become one of the largest marketplaces in Japan with an abundant inventory while networking nationwide, including OOH in the city, beyond the railroad domain. We also believe that through the automation of advertising transactions we can provide opportunities for efficient and visible advertising transactions.”

Srikanth Ramachandran, founder and group CEO of Moving Walls, says, “We are very proud that Moving Walls has been chosen as the technology platform to help launch what will be jeki’s largest automated ‘all-OOH’ market. Moving Walls has created a dedicated project team to localise and customise our technology, including delivery via a private cloud, guaranteeing the highest level of service to jeki.”

With this launch, jeki aims to revolutionise Japan’s OOH advertising market, making it more efficient, accountable, and measurable, while also increasing the value of the domestic OOH market.


Moving Walls is a media technology group with a presence across four continents and seven markets. Its supply-side subsidiary, Location Media Xchange (LMX) automates media owner processes and equips their assets with capabilities for enhanced and efficient delivery of OOH media.

jeki was established in 1988 as the first strategic subsidiary of East Japan Railway Company and is a general advertising agency that derives 70% of its total revenue from clients outside the group.
