Japanese online advertising – everything you need to know

Are you thinking about running online advertising campaigns to promote your business in Japan? The once traditional-media-focused nation has been seeing a dramatic shift to digital over the past few years. In this article, we compiled the latest trends surrounding online advertising in Japan as well as how to begin online promotions. 

Online Advertising in Japan

Japan has one of the most mature advertising markets in the world. In fact, it comes in third place for total media ad spending ($42.67 USD), just behind the USA ($225.79 billion USD) and China ($105.25 USD), and fourth place for digital ad spending1. In a country that promotes consumerism, the Japanese audience are often receptive to ads and are accustomed to being swarmed by advertisements on a daily basis. If you have ever been to Japan, you will know that billboards are everywhere in cities, and ads shout at you from every urban street corner. The same is true for public transportation and this is the norm. The Japanese are used to this massive input of information, every single day.

This also applies to online. Celebrity endorsements and anthropomorphised animated characters are heavily seen in both traditional and digital media.

For a nation known for its technological advancements, it is surprisingly behind its western counterparts when it comes to digital marketing. Many traditional companies still value TV and magazine ads over anything online. Yet in recent years, Japan has finally started to catch up to the rest of the world. Top digital trends in Japan include an increasing digital ad spend, companies switching their focus to online marketing initiatives, influencer marketing and a rise in video content.

Here is a graph that breaks down Japan’s digital advertising spend. As you can see, the largest share goes to search advertising, followed by banner (display) ads, social media advertising, video advertising, and classifieds.

Consequently, we will elaborate on the top three online advertising categories, and how you can use each one to grow your business in Japan.

Search Engine Marketing 

Search Advertising: Google and Yahoo! JAPAN

In Japan, Google is not the only major search engine. The other popular search engine platform is Yahoo! JAPAN claiming 18.3% of the market. In fact, if you are promoting to businesses, Yahoo! JAPAN has the no.1 share of PC users. We laid out all the features of both Google and Yahoo! JAPAN and their differences in our blog post here. In summary, we recommend advertising on both platforms to ensure maximum reach of Japanese internet users. If brand awareness is your goal, then try running display ads on Yahoo! JAPAN, which we’ll talk more about later under Display Advertising.

Social Media Marketing

Sponsored content and ads on social media are effective ways of promoting your brand, product or service to a certain audience. Unlike PPC search ads, promotions on social media will help to build an online community in Japan. Yet similar to search engine marketing, it’s important to understand who your audience is and choose your platforms strategically.

Here is a complete guide to social media in Japan to better understand in detail how the Japanese use each of the popular platforms. We will highlight the top platforms here for advertising:


LINE is the no.1 messaging app AND social media platform in Japan with 84 million monthly users2. It’s a super app similar to WeChat and WhatApp with multiple features and functions. If your target is mobile phone users, you can reach 90% of them in Japan on LINE. Businesses can open an official account, much like a Facebook company page, and use the interface for community management. LINE Ads use targeting features similar to Facebook and can appear on other apps within the LINE Ads Network. For more information, you can read our article on how to use LINE to promote your business to Japanese mobile users.

TWITTER (48 million MAU)

Japan’s most popular social networking site is Twitter. If you are targeting Japanese consumers, this is the platform for you to use to build your community and hear what your customers are saying. We recommend promoted content on Twitter if you are selling a B2C product.

INSTAGRAM (33 million MAU)

If you are a B2C brand with a target audience between the ages of 18 to 29 years old, your main platform should be Instagram. In fact, Japan comes in first place globally for the number of daily “stories” at 7 million per day3. Make sure to run sponsored ads here as well as partner with an influencer as influencer marketing is widely popular in Japan. 

FACEBOOK (26 million MAU)

Unlike most western markets, Facebook is used like LinkedIn in Japan where most people use it for business networking. If you have a B2B product or service, this should be your main social media platform. Ensure to run promoted ads, accounts, and events on this space.

Display Advertising 

The best platform for display advertising in Japan is Yahoo! JAPAN. It has the no.1 reach for PC users (beating Google) and you can reach 88% of mobile phone users in Japan4. Accordingly, infeed ads on mobile apps have great CTRs and CVs. Moreover, the brand panel ads on both PC and mobile get the most impressions, great for cost-effective brand awareness campaigns.
