About SBTS
A Partnership Built for Transformation
In 2017, SoftBank Corp. and BTS joined forces to form a strategic joint venture, initially known as SandBTS, now SBTS, with a shared ambition to drive innovation and operational excellence across the communications ecosystem in Japan and beyond.
By combining SoftBank’s strong market footprint and trusted brand with BTS’ global technology expertise and fraud protection capabilities, SBTS was created to pioneer new approaches to voice, messaging, and cloud-based services. From the start, the joint venture was designed to enable scalable, efficient, and secure communications in a rapidly evolving landscape.
At its core, SBTS is committed to Solving Global Complexity by simplifying communications infrastructure, enabling seamless integration, and unlocking value for its partners through powerful, future-ready solutions.

Life at SBTS
SBTS sits at a rare crossroads: a Japanese company, shaped by the collaboration between an American/Spanish team and a Japanese partner. A blend of openness and adaptability, complemented by precision and deliberation, defines how we work.
From Japan, we adopt a culture of structure, precision, and the Kaizen philosophy of continuous improvement. From Spain, we carry agility, creativity, and a people-first approach to problem-solving.
The result is a workplace where collaboration feels effortless, ideas flow easily across time zones, and cultural differences fuel innovation rather than friction. From Japanese language lessons that help colleagues from overseas fully participate in local business life to monthly Brown Bag sessions where teams across functions come together to share ideas and strengthen unity, we prioritize professional growth and keeping curiosity alive.
It’s a culture that balances planning with improvisation, thinks long-term but moves fast when it matters, and proves that two perspectives, joined well, can go further than one.
CSR
For SBTS, CSR initiatives focus on driving innovation, inclusion, and sustainability, turning corporate responsibility into measurable impact across the communities and markets we serve.
As part of this commitment, we support the Future and Coral Project, a SoftBank-led marine conservation effort in Okinawa dedicated to protecting and regenerating coral reefs for the health of our oceans and our planet.
