TOKYO-February 18, 2022-Internet Initiative Japan Inc. (TSE1: 3774), one of Japan's leading Internet access and comprehensive network solutions providers, today announced to livestream all performances of the Spring Festival in Tokyo which will be held primarily in Ueno from March 18 to April 19, 2022. IIJ will offer "free-viewpoint video" streaming, allowing viewers to move the camera's perspective (zoom in and out) to watch live performances with a sense of realism. Subtitles will also be available for some opera and lider performances.

The Spring Festival in Tokyo-one of the Japan's largest classical music festival-will offer paid live streams of approximately 65 performances in parallel with the real performances. IIJ will handle all operations necessary for these live streams-including ticketing, recording, transmitting videos, and providing video viewing site, etc. For all streaming operations, IIJ uses its video streaming platform, IIJ Media Sphere Service.

The streaming team will operate the venue cameras remotely from the streaming center, far removed from the concert halls, to save human resources for on-site support. IIJ has also developed a new smartphone app to make tickets more accessible using in-app purchases, increasing usability for viewers. The streaming tickets will go on sale at noon JST on March 1.

Through this support, IIJ will enhance its IIJ Media Sphere Service's functions and develop a streaming platform service that can provide everything from livestreaming for concerts and other events to a ticket payment system, thereby providing new viewing experiences to many customers.
