Starting with the direct operation of a mobile phone shop in Japan, GRASS has gradually expanded its services to connect with and support the international community.
Our beginnings at a mobile phone shop in Chiba
In the early years of our work in Japan, we directly operated Chiba Mobile, a mobile phone shop. Serving customers every day brought us closer to the needs of people from overseas who were living, studying, and working in Japan.
Customers came to us not only for help choosing phones and mobile services, but also with questions about procedures, communication, and everyday life. Each conversation helped us better understand the challenges they faced.
Growing our services by listening
Our experience at the shop showed us that customers needed more than telecommunications products. They also needed clear information, reliable guidance, and a place to turn to when they needed support.
Building on that experience, GRASS gradually expanded its operations. We developed SIM and telecommunications services while building customer support that better reflects people’s day-to-day needs.
From individual services to the GRASS Japan ecosystem
Today, GRASS aims to connect services and resources between Japan and Vietnam. Alongside telecommunications, the GRASS ecosystem is expanding into procedural support, digital services, and business connections.
Each service is shaped by a shared purpose: helping customers find clear information, understand the steps they need to take, and access support that fits their circumstances.
Continuing the journey with our customers
From a mobile phone shop in Chiba to the GRASS Japan service ecosystem, our growth has been shaped by real customer needs and the trust people have placed in us.
We will continue listening, improving our services, and building connections between Japan and Vietnam to support our customers in their lives and work.
