Spinshell Co., Ltd. (Headquarters: Bunkyo-ku, Tokyo; President and CEO: Kazunori Yokota; hereinafter "Spinshell"), in collaboration with UNWX Co., Ltd. (hereinafter "UNWX"), a subsidiary of USEN NETWORKS Co., Ltd. (Headquarters: Shinagawa-ku, Tokyo; President and CEO: Kazuki Kanda; hereinafter "USEN NETWORKS") of the USEN & U-NEXT GROUP, has launched the personal optical broadband service "Fits Hikari" starting Monday, March 30, 2026.

This service was born out of a partnership with Tenma Corporation (Headquarters: Kita-ku, Tokyo), known for its plastic storage products "Fits". Alongside the Fits brand, which has supported the "living" of Japanese households for many years, Spinshell aims to make "telecommunications as a life infrastructure" more comfortable and accessible.

"Fits Hikari" is a "Hikari Collaboration" model service utilizing the optical broadband network provided wholesale by NTT East and West to UNWX. In modern times where home traffic is increasing due to the normalization of telework and the spread of high-definition video content, we deliver a stress-free internet environment combining "speed," "stability," and "value."
