Unleashing New XR Possibilities with 5G Millimeter Wave

In an exciting fusion of technology and entertainment, Mawari Co., based in Shibuya, Tokyo, is collaborating with KDDI Corp. to host an unprecedented XR event named "mmWAVE DE VTuber presented by KDDI×Mawari - Special 3D Talk Live featuring Nagino Mashiro" on March 17, 2026. This innovative event aims to address the significant challenges faced by XR events, such as device loads from high-resolution 3D graphics, latency issues affecting user experience, and limitations on concurrent connections.

Breaking Down Barriers to XR Experiences

Traditional XR events often struggle with three main hurdles: 1) high device load due to detailed 3D graphics, 2) communication delays that detract from the experience, and 3) limits on the number of simultaneous participants. By combining Mawari's unique real-time 3D broadcasting platform “ARAWA” with KDDI's advanced millimeter-wave technology, the teams hope to solve these issues.

The event will allow up to 20 participants wearing AR glasses to interact simultaneously in a shared virtual space with life-sized avatars. This promises to be a groundbreaking experience for XR technology, facilitating real-time, two-way communication unlike anything seen before.

Innovative Features of the Event

Mawari's ARAW platform facilitates low-load, ultra-low latency, and high-definition rendering through a decentralized network of servers. This allows for the streaming of optimized data, significantly reducing the load on users’ devices while ensuring that intricate expressions and movements of the VTuber are recreated without delay.

Additionally, KDDI’s millimeter-wave technology will harness large-capacity, low-latency communications to deliver high-quality XR experiences to multiple participants at once, allowing attendees to share the excitement and emotion of live performance in a novel environment.

Future of Fan Engagement with VTuber Culture

One of the main attractions of the event is the appearance of Nagino Mashiro, a popular VTuber who raised over ¥330 million through crowdfunding. Her dynamic connection with a passionate fan base exemplifies how modern technology can significantly close the gap between fans and their idols, paving the way for a more intimate and immersive experience.

The Path Ahead: From Event to Infrastructure

Mawari intends to fast-track several initiatives based on the framework established during this event, including:

• - Permanent XR attractions in commercial facilities and theme parks.
• - Simultaneous XR live viewings across multiple locations.
• - New advertising and exhibition models utilizing intellectual property (IP).

In the future, Mawari aims to utilize advanced communication infrastructures to broaden the number of simultaneous connections, aspiring to host stadium-class events and city-wide XR experiences.
