La respuesta de So You Want To Learn Japanese es clara: ni se te ocurra. Da muchas razones por la que ninguna persona razonable se pondría a estudiar japonés. Por ejemplo, los kanji:
Kanji are letters that were stolen from China. Every time the Japanese invaded China (which was very often) they’d just take a few more letters, so now they have an estimated 400 gazillion of them. Kanji each consist of several «strokes», which must be written in a specific order, and convey a specific meaning, like «horse», or «girl». Not only that, but Kanji can combined to form new words. For example, if you combine the Kanji for «small», and «woman», you get the word «carbeurator». Kanji also have different pronounciations depending on where they are in the word, how old you are, and what day it is. When European settlers first came upon Japan, the Japanese scholars suggested that Europse adopt the Japanese written language as a «universal» language understood by all parties. This was the cause of World War 2 several years later. Don’t worry, however, since you’ll never have to use kanji in «real life», since most Japanese gave up on reading a long, long time ago, and now spend most of their time playing Pokemon.
