The reasons why to learn Japanese are a lot, I like how Lindsay summurizes those reasons in 9 reasons. Obviousely every one has his or her own reasons to learn a languages, but watching the video could help you to see if the reasons mentioned could also be enough to motivate you on long term in your japanese learning trip.

https://www.lingq.com is a website that offers classes for around 30 languages including Japanese, It is It has a lot of features. You have a lot of content like stories, while reading you can mark words you already know just with one klick and also the words that you don´t know. the result is a neat visual result which helps you to follow your progress and learn new vocabolary. Morover if you install their youtube extension in your browser you could even import the content that you like from YouTube and learn your preferred language with the content you like the most. The following video is from the owner of the website, he is very active and makes regular videos on his channel and he shares almost everything about his language learning experience. I don´t need to mention that, if he managed to learn 16 languages untill a fluent level, it could be really very usefull to watch his videos and expecially Japanese related ones as this post is about Japanese.
