I've been learning Japanese for about 4 years now.

There's two main parts to how I study:

• Flashcards at jpdb.io, I source them from anime and TV series, so I learn all the words in a particular series while watching it
• Immersion, I watch through anime and play games, and listen to podcasts (mainly nihongo con teppei) I also take the audio from anime, put it on an MP3 player and listen when on walks, public transport or running errands around the house

I also sometimes find myself going back to various apps and websites:

• Satori Reader
• Aomi
• supernative.io
• pitch.migaku.io
