Wi-SUN Alliance to Host "Open House 2026" in Tokyo, Showcasing Multi-Utility Deployment in Japan

The Wi-SUN Alliance, a global industry association dedicated to advancing interoperable wireless networking solutions, will host "Wi-SUN Open House 2026" on Friday, March 27, 2026, at the Ochanomizu Sola City Conference Center in Tokyo. Commemorating Wi-SUN's 14th anniversary in Japan, this event will bring together utility operators, technology companies, policymakers, and researchers to showcase the deployment of Wi-SUN technology in Japan's smart utility infrastructure and highlight Japan's role as an advanced market for multi-utility network integration. The event will also feature demonstrations replicating actual deployment environments. Admission is free, but pre-registration is required. Capacity is limited to 160 attendees.

Phil Beecher, President and CEO of the Wi-SUN Alliance, stated, "Wi-SUN was born in Japan, and 14 years later, Japan continues to lead with advanced deployments." He added, "The wireless standard for IoT Route, which embodies what this technology aimed to achieve, is a single open specification that integrates electricity, gas, and water on a large scale. This is not a future concept; it is an ongoing endeavor. We will elaborate on this at the Open House."

Since its establishment in Japan in 2012, the Wi-SUN Alliance has grown into an organization with over 300 member companies across 46 countries. It has also led the development of various key specifications. For example, Wi-SUN B Route is mandated for communication between smart meters and home gateways in Japan's electricity network, while Wi-SUN HAN, Enhanced HAN, JUTA, and FAN are widely used in Japan's energy and utility infrastructure.

Even today, Japan remains central to the development and deployment of Wi-SUN technology. The recently introduced Wi-SUN IoT Route further extends this foundation, enabling integrated wireless connectivity across electricity, gas, and water infrastructures with a single open protocol.

The Open House will also feature a solutions exhibition where Wi-SUN Alliance member companies will showcase technologies supporting next-generation wireless infrastructure. Exhibitors are expected to include Digi International, Itron Japan, Landis+Gyr Japan, Renesas Electronics, SEALSQ, Silicon Labs, and STMicroelectronics. Demonstrations will cover smart meters, IoT connectivity, Sub-GHz wireless SoCs, post-quantum cryptography for IoT devices, and multi-vendor network infrastructure.

[Keynote Speakers]

Mr. Michiaki Takahashi: Manager, DX Promotion Department, Tokyo Electric Power Company Power Grid, Inc. Mr. Takahashi, from one of the world's leading power companies, will speak on the introduction and utilization of the Wi-SUN IoT Route standard within his company. This standard enables joint metering and other functions across electricity, gas, and water networks through a single, integrated wireless infrastructure. This case is positioned as one of the most significant deployments of Wi-SUN technology in Japan and a major step forward for multi-utility DX.

"With the establishment of the IoT Route standard, a practical path for large-scale joint metering has been created," said Mr. Takahashi. He added, "Wi-SUN's open and interoperable framework plays a crucial role as Tokyo Electric Power Company Power Grid builds its next-generation digital grid infrastructure in the Tokyo metropolitan area."

Ms. Rumi Iizuka: Senior Researcher, Research Department, Foundation for Multimedia Communications (FMMC). Drawing on approximately 20 years of experience in domestic and international frequency policy and advising the Ministry of Internal Affairs and Communications on frequency management policy, Ms. Iizuka will discuss international trends in IoT business and regulation.

"The regulatory environment surrounding IoT wireless systems is evolving rapidly in all major markets," said Ms. Iizuka. She added, "For organizations looking to deploy large-scale IoT infrastructure, understanding the relationship between frequency policy and international standards is extremely important."

Dr. Hiroshi Harada: Chairman of the Wi-SUN Alliance Board of Directors / Professor at Kyoto University / Research Executive at NICT. From his position involved in the development and promotion of next-generation wireless systems, Dr. Harada will explain the current status, technical features, R&D efforts, and future development roadmap of Wi-SUN FAN, HAN, and IoT Route standards.

"Wi-SUN, once just one of many promising specifications, has grown into a proven global infrastructure technology with tens of millions of deployments in Japan," said Dr. Harada. He added, "The fact that FAN 1.1 and IoT Route are continuously evolving demonstrates the technical depth of our ecosystem and the increasing complexity of deployment challenges our member companies are addressing in the field."
