Business Overview

Tosei Engineering, a wholly owned consolidated subsidiary of Tokyo Seimitsu, services Tokyo Seimitsu’s measuring instruments, develops and manufactures automatic and labor-saving measurement equipment, and develops and manufactures semiconductor manufacturing equipment. The company has three main businesses, the automatic measurement, semiconductor manufacturing equipment, and service businesses. In the automatic measurement business, it provides automatic measuring instruments for automobile and home appliance production lines. In the semiconductor manufacturing equipment business, the company develops and manufactures wafer chamfering machines and other equipment. In the service business, the company calibrates, repairs, and maintains measuring instruments, and has established a network of industry- leading service bases.

In October 2023, the service business was transferred from Accretech Powertro Systems Co., Ltd., a consolidated subsidiary of Tokyo Seimitsu, and charge/discharge testing systems for testing and evaluating rechargeable batteries was added to the lineup of our service business.

Since our founding, we have been committed to providing unique technologies and services with the “customer first” in mind. In particular, from planning and proposal to design, manufacturing, and after-sales service, our technical staff with many years of experience and know-how listen directly to the needs and concerns of our customers, which is the starting point of our products and services. We consider the realization of a new low-carbon, recycling-oriented society through our products and services as an important management issue, and we are also working to solve various issues for the sustainable development of our customers and local communities.

For issues facing customers in the field of measuring instruments, there is a demand for more precise measurements in terms of energy saving and cleanliness of various products such as automobiles and home appliances. On the other hand, in the field of semiconductor manufacturing equipment, there is a need for improved wafer accuracy and larger wafer sizes to reduce the cost and yield of semiconductor chips, which are becoming increasingly miniaturized and highly integrated. In this way, in order to meet the increasingly sophisticated and diversified needs and to contribute to the creation and protection of a better environment, we are promoting various measures and technological development every day under the Group’s MOTTO, “WIN-WIN Relationships Create the World’s No. 1 Products.”

In May 2020, Tosei Engineering established an integrated management system and obtained certification under both ISO 9001 and ISO 14001 at the Kandatsu Plant, which functions as the head office. Currently, all three of our plants, including the Niigata Plant and the Nagoya Plant, have obtained certification, deepening cooperation between the plants and establishing a system that enables efficient operation of the management system. All business activities are conducted in accordance with our “Environmental Policy” which consist of the following five core policies: “1. Provision of environmentally friendly products and services,” “2. Reduction of environmental impact,” “3. Prevention of global warming,” “4. Prevention of environmental pollution,” and “5. Ongoing environmental conservation activities.” Through our products and business activities, we aim to reduce our electricity usage and CO₂ emissions, promote resource conservation, control waste generation and total chemical substance emissions, and continuously make improvements in order to achieve a sustainable society. In addition to contribute to local communities and meeting customer needs by balancing environmental preservation with product safety and high quality, Tosei Engineering also engages actively in companywide occupational health and safety activities aimed at maintaining a healthy and comfortable work environment and promoting a more sustainable workplace. Moving forward, as a member of the Tokyo Seimitsu Group, we will continue to build a robust value chain to realize higher value-added manufacturing and services, and play an active role in developing fair and transparent management activities that earn the trust of the international community.

Business Overview

Tosei Box is a Tokyo Seimitsu Group company that manufactures, sells, and provides services for delivery lockers. In the logistics industry, the increase in the number of parcel deliveries due to the expansion of the e-commerce market and the shortage of truck drivers have resulted in longer transportation times and increased re-deliveries, placing an increased burden on drivers. Delivery lockers are gaining attention as a solution to this problem. In addition, due to the impact of the COVID-19 pandemic and security concerns, demand for deliveries of packages that do not require in-person pickups are increasing. Therefore, we believe that the popularization of delivery lockers serves as a business that contributes greatly to society, and offer a variety of products suitable for the diversified needs of customers to make it easier for customers to install them and work on expanding our production capabilities. Recently, we have not only products for apartment buildings, but also products for companies. In addition, we are working on cutting-edge technologies such as contactless IC card keys, facial recognition systems, and e-mail delivery systems so that users can use them more conveniently and with peace of mind.

As a Tokyo Seimitsu Group company, we are creating a healthy, safe, and comfortable work environment through employee education such as a code of conduct through e-learning and a work improvement award system. We will also actively engage in sustainability activities to contribute to society.
