Ifyou plan to stay in japan for a bit it is highly recommended. It is not so cheap (15,000Y up// 100 euro up to 200-300 for the models with television) but it is priceless to be in a converation and quicly find the word that make you sound as an adult person instead of just saying “good/bad” “that thing” “yes/no”.
