The only independent search engines that support my native Japanese are Google, Bing, Brave, and Yep.

Of these, I generally search using Brave, and if I'm not satisfied with the results, I search again using DuckDuckGo.
I don't use Yep because of its strict bot restrictions.

Also, on the rare occasions when I need to do an exact match or a search using site:, for some reason, Brave and DuckDuckGo are useless, so I reluctantly use Google, which is a shame.
As someone living in Japan, I do not recommend QWant, which is recommended in this comment section.

As I've commented before, this is because the service geoblocks countries that have non-Western languages ​​as their official languages.

XユーザーのQwantさん: 「Some of you have reported difficulties using Qwant in several countries around the world. It is a difficult decision but we have decided to close access to our services in certain countries where we don’t believe to provide the expected quality of service. Our apologies for this.」 / X
