Japanese telecommunications providers are expanding cloud-based Private Branch Exchange (PBX) services to support digital transformation and flexible working environments.

In September 2026, DAIKO XTECH launched DAIKO XCOM, a service utilizing NTT Docomo Business’s ‘Arcstar Smart PBX’ platform. The service aims to assist companies in transitioning from legacy fixed-line systems to cloud environments by allowing the use of smartphones, PCs, and IP phones as extensions. Future developments for this service include the integration of AI voice technology for call summarization and trend analysis.

Following this, J:COM Co., Ltd. announced it would launch ‘J:COM BUSINESS Cloud PBX powered by Tobira Systems’ on November 30, 2026. Designed for small and medium-sized enterprises, this service leverages KDDI lines to provide fixed-number connectivity via mobile devices and computers, aiming to reduce management workloads and support teleworking.
