Im agree, Im a spanish speaker from Mexico and its difficult to use Wanikani in english. I need to learn kanjis + a lot of new english words. There are books of the complete nemonics in spanish, the name is “Kanji para recordar”, then I think its possible to use this book as a source of information for wanikani company and make a deal with the autor of the book to use his book for the wanikani spanish version. the price of the book is about 32 usd, I think its a good chance to make a deal with them.
Please wanikani, try to find new ways to make profitable your business and help more people in the world.
Think about it, its really difficult to use this software for non english speakers, as more far Im using wanikani, more difficult to understand vocabulary of the english nemonics.
