R International School - operated by R Group

About us

R International School is a Language School focused on real-world usage, not textbook perfection. We help learners develop language skills that work in actual business, daily life, and decision-making environments — where how you say something matters as much as what you say. Our approach goes beyond grammar and vocabulary. We focus on clarity, positioning, and nuance, so your message is delivered with confidence, accuracy, and the right level of professionalism.

All lessons are conducted online.
Our programs are designed to be flexible, structured, and accessible from anywhere.

Our Vision

Language should never be the reason you feel uncertain, misunderstood, or underestimated.

Our vision is to transform language from a set of rules into a Strategic Tool — one that allows you to use/express your ideas, intentions, and value clearly across cultures and professional environments, not just "understand" them. R International School supports individuals who operate internationally and need language skills that reflect who they are and where they stand.

Why we provide Online Lessons?

Our online format allows learners worldwide to study together from anywhere in the world.

We believe consistency is essential in language learning, and flexible scheduling with easy access supports a stress-free environment that enables long-term commitment and sustainable progress.

Flexible Lesson Scheduling

We understand that your schedule isn’t fixed — and neither are our lessons. Sessions can be arranged flexibly to fit your work, travel, and time zone, making it easier to stay consistent even with a busy lifestyle.

Customized Lessons

Every three months, we conduct a level evaluation to assess each student’s progress. This includes a recap session and a one-on-one consultation to ensure accurate class placement and personalized lesson content.

Practical, Real-World Focus

Our lessons are designed around how language is actually used. Emails, meetings, chats, and real situations become learning material, so you can apply what you learn immediately.

Japanese and English support available

Lessons can be conducted with bilingual support in Japanese and English, allowing for clear explanations, deeper understanding, and efficient progress without unnecessary confusion.

ADULTS PROGRAM

Program Overview

This program is designed for learners who want to use English confidently in real-life situations.

Our lessons focus on practical communication skills for work, international interactions, travel, and daily life—rather than textbook-only learning.

We emphasize not only grammar and vocabulary, but also how to communicate effectively and naturally in real conversations.
Students learn how to express ideas clearly, appropriately, and professionally.

Because every learner has different goals and backgrounds, we tailor each program to individual needs, experience levels, and lifestyles—making it easier to stay consistent and motivated.

All lessons are conducted online, allowing busy professionals to learn from anywhere without disrupting their daily schedules.

Our goal is to help you move beyond hesitation and build the confidence to use English as a practical tool in your life.
