Make videos and games more comfortable for the whole family. Introducing "Fits Hikari," an ultra-high-speed fiber optic service with up to 10Gbps!

SpinShell Inc. (Headquarters: Bunkyo-ku, Tokyo; President and Representative Director: Kazunori Yokota; hereinafter "SpinShell") has collaborated with UNWX Inc. (hereinafter "UNWX"), a subsidiary of USEN NETWORKS Co., Ltd. (Headquarters: Shinagawa-ku, Tokyo; President and Representative Director: Kazuki Kanda; hereinafter "USEN NETWORKS") of the USEN & U-NEXT GROUP, to launch the personal fiber optic service "Fits Hikari" starting Monday, March 30, 2026.

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

"Fits Hikari" is a "Hikari Collaboration" model service that utilizes the fiber optic network provided wholesale by NTT East and NTT West to UNWX. In today's world, where communication volume within the home is increasing due to the establishment of telework and the spread of high-definition video content, we provide a stress-free internet environment that combines "speed," "stability," and "affordability."

■ 4 Points that make daily life more comfortable with "Fits Hikari"

### 1. Supports "up to 10Gbps," among the fastest in Japan. Smooth even when the whole family is connected at once. We offer a 10Gbps plan that makes it difficult for speeds to drop even when watching 4K/8K ultra-high-definition videos, downloading large-capacity games, or when family members use devices in separate rooms. You will be freed from the stress of frozen online meetings and waiting for videos to load.

### 2. Standard provision of "Next-Generation IPv6 Connection" that is resistant to congestion. We have adopted a connection method that is less prone to speed drops even during times when users are concentrated, such as at night or on weekends. Because you can maintain stable communication quality at all times, you can use it with peace of mind for remote work and online classes.

### 3. Reliable NTT infrastructure that connects anywhere in Japan. Compatible with the "FLET'S Hikari" areas of NTT East and NTT West. Because it can be used over a wide area nationwide, you can continue to build a high-quality internet environment even after moving.

### 4. Subscriber benefits that brighten up your life, only possible because it's the "Fits" brand. We have prepared special offers to help organize your household finances and home, which is only possible because we are the storage brand "Fits."
