Don’t worry if you don’t have NDS console(coz me too ^_^), you can use NDS emulator on PC. Now I’ll review about this education game “問題な日本語”(mondai na nihongo, Japanese Questioness). Actually this game aimed for Japanese kids(6-15). Learning how far they Japanese comprehension. This game very appropriate for non-Japanese to learn Japanese in easy way. Either beginner or advance can play this game, but you must be able to read hiragana, katakana, and some kanji if you want to play without any obstacle.
