Why do you write Nihongo instead of Japanese? Also, learning English doesn't require learning 2400 separate characters and two 24 character syllabaries that change their meaning depending on the combination just to read a newspaper. Kanji to write the words and hiragana to write something that you can't write with kanji (lol), and katakana on top of that to write foreign names. Whereas with European languages you can express yourself using only 24 characters. So no, Japanese isn't a superior language (only a weeb or a Japanese would claim that).
Why? Because "nihongo" means
japanese language. if you just say "Japanese" it could refer to people, culture, country, literally anything to do with Japan. I write that instead of "Japanese language" because it's easier and quicker. It's like choosing to say "English" instead of Australian or American or British or etc.
English still manages to be 100X more complicated, even with less characters. But anyway what your saying isn't true. Japanese mainly uses hiragana. Sure there is a kanji for many things, but the majority of japanese don't bother to learn 90% of kanji, only the basic stuff they need. That's because Kanji is actually Chinese. Kanji is a relic from the past when they adopted chinese into their writing system. It's being slowly phased out. Besides, they're like pictures for words. See them often enough and you'll easily know what they say.
The katakana is only used for borrowed words, foreign words, and names, etc. Or for yelling and sound effects. The katakana is so incredibly easy, I learned how to read and write it in less than 3 days. Plus, the second you can read and say katakana characters, you will automatically be able to read every katakana word AND understand what it says. Without needing a dictionary. Because katakana is literally just the japanese way of writing sounds.
Also, particles. Learn the 10 basic ones, and you will almost always know the most important structure details of a Japanese sentence. I may not be fluent, but because I know particles, I can listen to any Japanese sentence now and always at least know if it's a question, a statement, directions, agreeing or disagreeing, and many more.
Any new language seems hard, but seriously, Japanese is a way more sensible and easy-to-learn language than English. The reason why the two find each other difficult is because they are so different. But as an English speaker who has tried learning multiple different languages, I was impressed by how sensible and easy Japanese language really is.
There's a reason why they say "easy peasy Japanesey"
Spanish is way harder too imo. My exes parents were from El salvador and Argentina. They both spoke spanish. But neither of them could fully understand each other even after 25+ years of marriage, because the language is so complicated, and they say many things differently.
Out of every language I know, I tell everyone that English is horrible with many confusing and contradicting rules, and one of the most overly complicated second only to probably Cantonese and Mandarin.
