As a Digital Marketing agency in Japan, we are often asked this question from our clients. This article introduces some of the latest statistics on Japan’s search engine market share.

Search Engine Trends In Japan

When we examine the historical data, the results also show that Google has owned most of the market share in Japan over the past 10 years. Yahoo’s market share increased up to about 37% at the end of 2015, but it has been decreasing in the last five years. Google is now at 77% overall.

Search Results Listings Differences Between Google and Yahoo

As widely known, Yahoo Japan has been using Google’s algorithm since 2011. With their similar functionalities, optimizing your website for Google can also yield results for Yahoo in terms of SEO.

However, Yahoo Search will often show different items in the organic search results. Take a look at the screenshot below for the similarities and differences. Yahoo JP is on the top, and Google is on the bottom. The keyword used for this example is オリジナルTシャツ (Original T-Shirts).

Key points:

  • Organic search results (shown in blue) are similar across both platforms. In both cases, you can also see rich snippets, in this case FAQ, for some of the pages. You can read more about structured data in this article.
  • Paid search ads (shown in red) are displayed on both platforms, but for different products. This points out the fact that Google Ads and Yahoo Ads have different display tools and bidding systems.
  • Other features, such as Google Local Maps Pack and Yahoo Shopping Listing, are specific to each platform (shown in orange).

Is Yahoo More Popular than Google?

If you search this term, you will get a very mixed result. Some sources might say that Yahoo is the most popular site. For example, this 2021 report by Nielsen outlined the online user trends in Japan  as below.

Average Monthly Reach

  1. Yahoo Japan – 9%
  2. Google – 5%

This data indicates that Yahoo is more popular than Google in Japan.

On the other hand, the data in the earlier section clearly indicates Google is more popular. How can it be? Let me clarify these 2 points.

  • Yahoo is the MOST VISITED SITE in Japan.
  • Google is the MOST USED SEARCH ENGINE in Japan.

In Japan, Yahoo is one of the most used news media. In fact, Yahoo is the number 1 visited news site in Japan. It is especially popular among users under the age of 30.

Besides the news, Yahoo has popular content such as finance, weather, and over 100 other services. These services as a whole make Yahoo the MOST VISITED SITE in Japan.

Most users consume content on Yahoo, but do not use Yahoo as a search engine. As the data indicates, about 77% of the online users in Japan use Google as their main search engine.


Google is the most popular search engine in Japan with a share of 77%. Yahoo Japan is the #2 search engine; however, they use Google’s core search algorithms. It should be noted, there may be differences in the search results pages due to Ads, local Maps packs, News items and more.

On the other hand, Yahoo is the most “popular” website in Japan, which sometimes leads to some confusion.

From an SEO point of view, it is safe to treat both engines the same. However, for paid search ads (PPC ads), the ads display tools are different. As a result, there are differences in what ads are displayed.

Overall, understanding the search engine market share in Japan, including the similarities and differences of top search engines, is an essential piece to devising the best digital marketing strategies for the Japanese market.
