About Us

① Project Overview

Our platform is a Japanese-learning system designed to help learners master verb conjugations efficiently through
‍natural conversations spoken by native Japanese speakers.
It enables users to learn both business conversation and casual, everyday conversation at the same time.
With the theme “Making Japanese more accessible and enjoyable,”
we developed this platform especially for learners in Vietnam,
while also providing a learning environment where people around the world can experience and
acquire living, real-world Japanese through culture and conversation.

② Team & Contributors

Through teaching Japanese to Vietnamese staff in business settings, at VOV, and in trading companies,

■ Author: Kensuke Ooi
Author of “Japanese for Vietnamese Learners.”
‍An active Japanese-language teacher with teaching experience across four countries,
including VJCC, Hanoi Foreign Trade University, and middle schools in Hanoi.
Questioning the conventional “masu-form–centered” teaching method,
he advocates an approach where verb conjugations are taught comprehensively and at once,
and provides practical, real-world Japanese instruction based on this principle.
