Non Indoeuropean language in Japan similar to Basque

In Japan there is a group of people known as the Ainu that speak a language that has some similarities with Basque.

The site were the comparision is made is as follows:

Even though the words don't mean exactly the same thing and written the same way, it's not diffecult to conect the two.
Does anyone know of any other languages that can be grouped with these two?

(Even though the words don't mean exactly the same thing and written the same way, it's not diffecult to conect the two.)

Even though the words don't mean the same thing and not written the same way, it's difficult not to connect the two.

Wow! That is a very interesting article. I would never have imagined that Spain and South America were connected way before Pizarro's invasion! Amazing. Not to mention Japan.

That contains misinformation.

"Other well-known names were similarly assembled such as Hokkaido: oka-aidu: oka (big meal) aiduru (looking forward to):"

Hokkaidou does not come from that. "Hokkai" is a contraction of "hoku kai", and "dou" is added to it...

"hoku" - sino-japanese for North
"kai" - sino-japanese for Sea
"dou" - sino-japanese for "road" (it was used in the Meiji era to refer to regions of Japan consisting of multiple provinces)

So, "hokkaidou" means "North Sea Region", and is composed of Chinese morphemes adopted by Japan.
