What an unforgettable evening it was in Singapore on the 6th of March 2025, at our Sake & Media Strategy Event in Singapore, where 30 industry professionals gathered to explore the future of Japan’s OOH landscape and its global impact.
The event began with an opening address by the esteemed Koichi Inaba-san, Senior Corporate Officer – Deputy Director General of Media Solution HQ, Head of Digital Signage Business Division, and Director of MASTRUM, setting the tone for a remarkable evening. This was followed by expert presentations from Takayuki Owada-san (Deputy Manager – jeki JR East) and Srikanth Ramachandran (Founder & Group CEO – Moving Walls Group), who shared valuable insights into the groundbreaking innovations of MASTRUM and GLOOH (Global Out-of-Home) respectively. Special mention to Masaru Yamaguchi-san, Director – Center of Promotion – MASTRUM, whose contributions were vital for the success of the event.
Takayuki Owada-san introduced MASTRUM, powered by Moving Walls, is an OOH platform operated by East Japan Marketing & Communications (Jeki), a DSP/SSP company. MASTRUM supports not only transit advertising but also street advertising, retail media, as well as analog media such as hanging posters and outdoor sheet advertising.

The platform is seamlessly connected to leading DSPs including DV360, The Trade Desk, Stackadapt, and Mediasmart, alongside Moving Walls’ MAX; a comprehensive universal OOH planning, optimization & reporting platform, and MASTRUM’s own DSP, enabling advertisers to easily access and purchase premium Japanese OOH inventory.
