Nowadays, supply-side platforms are an amazing way to monetize your website or blog in Japan. However, you have to find the perfect one to make the most profit possible. Because of that, we’ve gathered the best supply-side platforms for Japanese publishers in 2022. 

Internet traffic in Japan is no joke, having in mind that is one of the countries with the fastest internet in the world. Its population is approximately 127 million people, and more than 90% of it uses the internet. We can see that it’s a huge market for online advertising since more people are online to check our product every day.

However, it can also be a disadvantage to people who are starting to create a website or blog, because the competition is huge and sometimes you can even make people notice your blog. For that, you need to create quality content and promote your product ad much as you can. Social media is a huge part of this since it can help you to attract an audience.


Once you have enough engagement and a solid amount of viewers, you can start thinking about monetizing your website or blog. For that, we highly recommend using a supply-side platform (SSP), which enable publishers to monetize their websites by producing and selling ad inventory to marketers on an impression-by-impression or visitor-by-visitor basis. 

With a SSP, publishers may give advertisers improved insight into individual impressions and obtain quick clarity into advertising demand by selling advertisements in real-time. This guarantees that publishers sell their inventory at the best possible price and maximize the value of their ad inventory.

With this being said, here we present to you the best supply-side platforms for Japanese publishers in 2022:
