Rubicon Project helps launch Japan’s first premium publisher co-operative


Japan’s first premium publisher co-operative, DELTA Publisher Alliance, has just launched with the help of ad marketplace Rubicon Project as a programmatic partner for its digital ad inventory.

The alliance will launch with three Japanese publishers – Succor King, J-CAST News and AUTO SPORT. Combined they have a monthly reach of over 16m unique visitors and reach 114m page views a month.

For publishers, the co-operative means that their entire mobile, app and desktop inventory will now be available for advertisers through Rubicon Project’s platform to cater to demand from thousands of marketers globally.

Tomoyuki Ikeda, Managing Director for Japan, Rubicon Project, says:

“Co-operatives are a proven way for publishers to aggregate their inventory and compete effectively in the digital space. The launch of DELTA Publisher Alliance is a huge step for this robust marketplace and will further fuel the growth of digital advertising spend in Japan, which is forecast to be worth $4.42 billion in 2016, growing to over $6 billion by 2020.”

The co-operative is the 12th powered by Rubicon Project and continues a global trend of publisher alliances launching across the world over the past two years. This trend has already seen various co-operatives spring up in 2016 across the UK, US, South Africa and now Japan.

Tetsuya Shintani, Country Manager for Japan, The Trade Desk Japan K.K., adds:

“Private marketplaces have recently taken off in Japan. We understand the value of audience data at scale across multiple premium publishers and have been delivering top-class PMP executions in the US and Europe. We have long been working with Rubicon Project on this nascent area in Japan, and the launch of DELTA Publisher Alliance will bring great benefit for buyers. We expect that this will greatly increase the programmatic transactions of high quality premium inventory in Japan.”
