Problem Statement

Living in Japan, yet unable to speak the language

First of all, there's no one to practice speaking with. Even when students have Japanese friends, those friends are often too polite to correct their mistakes. Textbook Japanese simply doesn't work at official counters or in job interviews. As a result, even after years in Japan, all they can say is "Daijoubu desu" ("I'm okay"). A lack of real-world conversational ability is one of the biggest challenges facing international students today.Polite friends and static textbooks fail to build real-world skills, leaving international students stuck on basic phrases like "Daijoubu desu" for years.
