Property utilization business
An authentic natural hot spring-fed bath in Tokyo, combined with a real estate rental business
Saya-no-yudokoro Co., Ltd. is a place where you can forget that you’re in Tokyo, without ever leaving. Let out a sigh of relief from the bottom of your heart as you forget everyday hustle and bustle and enjoy a calm, gentle moment of pure relaxation.
We also rent out the adjacent land and property in an effort to revitalize the surrounding area and contribute to the local community.

A painstakingly managed hot spring
A rarity in Tokyo, the natural hot spring that feeds our bath has a unique olive-green color. Mildly alkaline with a pH of 7.4 and classified as a strong saline hot spring, it has a high concentration of iodine-rich sodium chloride. That salt adheres to bathers’ skin and keeps sweat from evaporating, providing excellent heat retention. As a result, you’ll feel warm long after bathing and be less likely to experience post-bath chills. Reflecting the supreme importance we place on safety and hygiene, we manage this hot spring facility in a meticulous manner.
Providing a high-quality environment
Surrounded by greenery, the open-air bath offers a different ambiance to enjoy during the day and at night. Guests can also rent a private bath. We work day in and day out to provide a high-quality environment with exceptional cost performance.
Soothing Japanese garden
A carefully maintained Japanese garden offers a glimpse of seasonal natural beauty from inside the building. Small birds known as “warbling white-eyes” visit from time to time, allowing you to enjoy nature’s rich expressiveness. Enjoy a soothing moment in a traditional Japanese garden in Tokyo that rivals its counterparts in Kyoto.
Flavorful 100% buckwheat soba noodles
The hot spring’s restaurant, which recreates the ambiance of a traditional Japanese home, serves a selection of creative Japanese cuisine prepared with seasonal ingredients, including “juwari” soba noodles made with 100% domestically sourced buckwheat flour.

High-performance materials business
Our high-performance materials business underpins emergent technologies
Tokkin Kinzoku Excel Co., Ltd. has been manufacturing high-performance materials since 1940. We refine materials' mechanical properties through cold rolling process, clad different materials into a single composite, and apply resin or solder to metal surfaces. By aligning specifications with each customer’s needs, we’re able to create high-quality, high-value-added materials.
Tokkin materials, hard at work behind the scenes
Tokkin materials are utilized in a wide range of products, from everyday items like smart devices, computers, automobiles, and gaming consoles to industrial equipment such as semiconductor manufacturing systems, medical devices, and textile machinery. Although often invisible on the surface, these materials play an essential role behind the scenes in ensuring that these products perform to their fullest potential.
Solving problems with custom-made products
•Fine-grained alignment of specifications with customer needs
•Sourcing of raw materials from anywhere in the world
•Minimum thickness 2.0 μm
•Prototyping from postcard-sized samples
•Mass production starting at 100 kg, special specifications from 1 kg
•Robust support until a solution is reached

Creating new material properties collaboratively with customers
Tokkin not only selects the most suitable materials from existing products, but also collaborates with customers to create even better materials. To do so, we listen carefully to customers’ needs and challenges and repeatedly refine and prototype prospective products as we work towards solutions.
Proposing overall optimization
We not only address challenges related to material properties but also consider the entire process up to the final product while offering proposals that lead to overall optimization, for example through yield improvements and process efficiency enhancements.
