Is Japanese a harder language to learn than any European languages (e.g. French, Spanish, German, Italian, Czech, etc.) out there?

I'm Italian native speaker and I study Japanese by myself. It's way harder than English or French because of its grammar and writing system, very different from European languages.

It's easier for an Italian than for an English or French as the sound of vowels is the same in Japanese as in Italian (however, apart from the vowels, Japanese isn't easy for Italians as well as for other Europeans. We need to study a lot).

I don't know that it's harder, but it's very different from most European languages. It's from a different language family, so there are no cognates or similar-sounding words. Its word order is subject-object-verb, which is different from that of English. The writing system is totally different, though I don't know that it's any more insane than English's bizarre spelling system.

Yes, for an English speaker.

Others have provided other useful info.

Here is one example.

I am hungry - translated into natural Japanese and then back into English as literally as possible:

stomach - [subject marker] - emptied - is (with a suffix indicating normal politeness).

yes

To become fluent in Japanese it will take on average 4 times longer than for any Germanic or Romance language, and two times longer than for any Slavic language (somewhat less for Basque, Finnish and Hungarian).

Hmm! Naa, first learn the alphabet!

Yes. It's extremely different. It is one of the hardest languages for an English person to learn.
