What do Japanese use to reverse image search on Yahoo

I'm trying to reverse image search some Klonoa art from the early 2000s, likely came from the artists personal website before boorus/pixiv existed. What site do Japanese use to reverse image search on yahoo japan? Or is there another search engine Japan commonly used in early 2000s?

Here's the image uploaded to pixiv by the original artist years later
