I want to learn Japanese. What is a good way to get started?
You could start by learning, first of all, how the writing system works, such as hiragana and katakana.
After that, you start the basic grammar, for example some words such as すし(sushi), and after you can start with kanjis for some words, like わたし (means I) can also, and is commonly written as 私
That's fine thanks,  so please provide a list of free resources to start my learning, and provide the web url links, that will be greatly appreciated.
