Who are we?

"UNITY"=各個人が自分とは異なる相手の立場、背景を尊重できる社会  これを、私たちは活動理念とし、2025年大阪・関西万博にて、"e-Symphony"=100カ国の学生とのオンラインオーケストラ を行うことで、実現できると信じています。

We are the student organization a-tune, aiming to participate at the 2025 World Expo in Japan. Officially being recognized by Osaka University, the events we organize initiate international exchange by bringing people closer and playing music together.

A society where people from various backgrounds respect each other we call UNITY. That is our goal and gives us motivation. Through bringing people from 100 countries together to perform in an online orchestra in the EXPO 2025, we are strong willed to contribute to UNITY.
