Possibly more importantly, Finland shares a common history and religious background with Europe. There are many, many idioms and ways of looking at things that stem from historical and religious influences. Grimm's fairy tales, for example, spread through Europe widely, but not through Asia or the middle East. On result is that while Chinese often has sayings with a similar meaning as English ones, their literal meanings are very different. In European languages, on the other hand, the sayings are often literal translations.
Linguists whose focus is on Japanese generally do generally consider it an Altaic language. This includes the most prominent, such as Marshall Unger (under the name Macro-Tungusic). The classification is still somewhat controversial, but I think it's largely for historical reasons. Local Japanese language scholars, who are not linguists, have traditionally subscribed to the view that Japanese is special and separated from all other languages. Modern linguists do not generally subscribe to that view, regardless of whether a proto-Altaic existed or not.
In any case the points about shared cultural, historical and religious heritage still apply. Finns learning English have far more of a shared cultural framework to work from than Asians learning English do.
In any case, it's completely different than anything most people ever heard (I've been living in Finland for close to 5 years, and it just hasn't clicked for me yet, despite being very fluent in 3 languages and dabbling in 3 others).
You should maybe change the people you hang out with. I befriended "Finnish rednecks" for a year but that helped me go from 0 to fluent (YKI 5) in 2 years.
My friends in high school would attempt to construct perfect sentences in their head before speaking a word, which made them poor conversationalists.
