Oh I definitely need this
Whenever anyone asks about Japanese resources I have to link my favorite book!!!
Japanese verbs are SO EASY but the way they tried to teach it in school was totally convoluted, because they insisted on teaching you the desu/masu form of the verb without just giving you the base. This little book was a godsend for me with its handy chart and clear structure. Highly recommend for anyone studying Japanese, especially if just starting out.
The basic/intermediate/advanced Japenese grammar dictionaries published by the Japan Times are also excellent reference material for learners. I got a lot of use out of the basic and intermediate ones when I was studying for my degree (they are often cheaper to import from Japan than buy overseas. Amazon Japan has them at a decent price).
I just translate manga as a hobby. I know maybe just enough to know Japanese and anime otaku Japanese isn't quite the same thing.
みなさん、日本語は上手になるといいです。がんばる！
I recommend using the Nakama textbooks to study as well, I personally prefer them over Genki, especially since Nakama teaches you Keigo along the way compared to Genki that teaches you Keigo way later. Also Nakama has a kanji chart and index in the back of the books, but both textbooks come with CD's as well that helps with listening.
If you're looking for things to watch in order to improve your Japanese, I would recommend NHK World or Japanese game show programs (they're a little bit easier for me to watch, even while in Japan, I can understand them far more easily compared to other television programs. Plus they're fun to watch too.)
I'm interested XD I learned a bit of hiragana back in highschool. I couldn't continue now 'cause of how busy my life is but I still wanna learn! Watashi no nihonggo wa warui desu, demo oshiete kudasai! I don't have any japanese characters on my keyboard so i can only type the romaji lolol Do I pass the grammar test? XD
You don't need a Japanese keyboard to type in Japanese. On Windows, you can add Japanese input from the language and region section of the control panel, on Mac you can add it under Settings>Keyboard>Input Sources. Both of these allow you to type in romaji, and it will automatically convert to kana and kanji.
THIS. THIS book is amazing for learning kanji (though it is best to just read and write kanji over and over again), but this book is incredibly helpful. No other book is needed for kanji studying.
I've been failing in studying Japanese recently, but last year, I did take the N3 test and passed! \o/ It was quite a lot of work to study for, but it was fun and totally worth it. I didn't think I wanted to take it, but I'm glad I did. I definitely recommend taking the JLPT some time, even if it's N5!
I will recommend the Genki book system.They are well structured and easy to work with, even if you learn by yourself (always fiunnier with a friend though). They can be bought on Amazon.
There are Genki I and II plus workbooks for each and answer books if you want to correct yourself. They also include CDs for pronounciation and listen practices.
Remember the Kanji is also a great tool for memorizing kanji, which is usually what is the hardest part about kanjis. Can be found on Amazon.
I've also found some free apps for android that I like:
Ankidroid - A flashcard app. Has resources online for download, like the full glossary for the Genki books and such.
LingoDeer - Small lessons for grammar and vocabulary complete with flashcards and notifications for practice times. Versatile in it's level, you can pick if it writes in romaji, kana, kanji or all of the above. Also have listen exercises. Reminds me of the Genki system, just less thorough.
Infinite Japanese - A game where you learn basic glossary, numbers, colours etc. You can set the level difficulty with romaji, kana or kanji.
TangoRisto - Reading material in japanese, news, fairytales etc. includes furigana and glossary.
Jsho - Japanese-English dictionary. You can type in with romaji and also shows order and such.
Eggbun - Haven't really used this yet, but have it downloeded. Seems like an app where you can chat in Japanese with a... teacher? Not sure if it's a real person or an AI or what it is...
I hope this can help you guys! 
I did that before and was such a hassle to switch between English and Japanese. So I just use Lexilogos instead. That site is very useful but it doesn't do the small "tsu" very well.
Obviously do what works for you, but there are keyboard shortcuts for changing the input language. It takes a little while to get the hang of it, but after a while it just ends up as muscle memory, and you do it without even realising.
Apps never work for me (it does for some of my studymates though!), but I defo agree with Genki and Remembering the Kanji! These are my two main tools and I feel like I'm progressing, even though I've only started learning a few months ago ^^
Also you can practise using memrise (an example: https://www.memrise.com/course/43670/remembering-the-kanji-volume-1/), no need to pay for anything to review content 
Gonna check the other references given here, quite curious about Nakama mentioned by @Starstruckroyal
@Cavechan why is this book so good for learning Kanji? Would love to compare with Remembering the Kanji (the mnemonic system works quite well for me, but I'd love to see other ways) ^^
Look at you guys (*´∀｀)
WWWJDIC1 - a neat Japanese dictionary site available online and as a mobile app.
Human Japanese1 - A game-oriented helpful resource.
Textbooks
Listed are the books I've been using for the past year or so in my university.
- For writing (make sure you practice reading the senteces!):
- For speaking (it's important to listen to the audio files the books come with, and responding to the drills provided in a timely manner.):
Japanese the Written Language: Part 13
Well, changing regions and languages sometimes changes the letters in songs on mp3s if they're in Estonian or Finnish, I rather have my Vinny Puhh songs names look like they're in Estonian. I mean it's great for playing games that only work in Japanese but some bugs with that.
I haven't used Remembering the Kanji so I can't compare, though when I did my research on which book to buy I did ultimately settle on Kanji Learner's Course. I believe the difference was RtK didn't have ways of remembering how the kanji is read? Only the meaning of the kanji? KLC gives a TON of information on each kanji and it has different ways of looking them up too. It has some references in the back too, such as kanji used for names.
