Do it! It’s fun.

Korean:
-Talktomeinkorean.com (they really break everything down. Great resource for learning grammar.)
-Learnwitholiver.com (they have a lot of other languages too so definitely check it out even if you’re not interested in learning these two languages I’m mentioning.)
-Viki streams Korean (, Chinese, and Japanese) dramas and movies w/ subtitles and recently added “Learning Mode” which allows you to see both English and Korean subtitles and to be able to click on a word and get the definition then and there.
-[App] “HiNative” (ask questions about the language if your confused about something, ask for translations, ask about grammar, etc. you get answers pretty quickly.)

Japanese:
-Animelon.com is a site you can use to learn Japanese with Anime. I’m not much a fan of anime but it’s brilliant for learning. Getting vocabulary, understanding grammar, practing reading and listening skills. You can set English, Japanese and Romanji/pronunciation while watching anime and other things. Not to mention, you can also see the whole script on the side.

-Japanese Ammo with Misa (a youtube channel)

Learning Kanji (Japanese writing system) and vocab:
a dictionary app called “NiHongo” is all you need. You should be able to find it by typing “NiHongo app”, it’s the blue and green one.
However, before learning Kanji, you should definitely learn Hiragana and Katakana first. It’s like... two alphabets lol

My suggestion is learn Spanish. It is one of the "romance" language's. The "romance" languages include Italian, Spanish and French. While they are different, it is easier to understand the other's when you know one of them as they are similar.
