GENKI 1 2 An Integrated Course in Elementary Japanese 4 Books (Third edition) Bundle Set

Os livros chegaram em perfeita condição, bem embalados e com o cheirinho de livro novo haha

Not as often recommended by native Japanese speakers, but they don't necessarily know how native English speakers learn. You need to really put in the time to make proper use of these. That being said I can't imagine a better way of learning Japanese, it's very clear and there's an app online to hear all the native pronunciations. Properly engaging with these two books with workbooks you'll be able to read, write, and speak Japanese at an N4 or A2 level. They're designed for use in a class, but honestly you can learn on your own (though it'll likely be a bit slower.)

Llegaron en excelentes condiciones. El envío demoró exactamente una semana, varios días más pronto de lo que estimaba Amazon. Me encantaron, me están sirviendo mucho y son muy bonitos.

Danke

It is what I was asked to get as a present for my son learning Japanese
