Sincere Co., Ltd.
We produce a safe, low-priced and high-quality cleaning agent for potable water tanks.
We offer “Pearl Green,” a cleaning agent for potable water tanks, to building maintenance service providers and water tank cleaning companies throughout Japan. It is a safe, high-quality, low-priced water tank cleaner made entirely of food additives and can quickly wash out tough strains on potable water tanks. In addition, it is easy to rinse the tank after cleaning. We handle everything in-house, from procurement of raw materials to production, quality control and product sales, which is why we are able to fill our customers’ orders immediately. We have eight variations of “Pearl Green” for different types of tank material and contamination requirements.
[Company strength] As a member of the Hoyo Group of Hoyo Seiko Co., Ltd. in Oita prefecture, we took over the manufacturing expertise from other group members and developed the water tank cleaner “Pearl Green” in collaboration with the Oita Industrial Research Institute and Oita Industrial Creation Organization. Since we can produce the cleaner in small lots at our own plant, we are able to immediately respond to customers’ needs. We started with only one type of “Pearl Green” based on our customers’ input, but as of September 2015, we had a total of eight types in order to meet the requirements for different working environments, tank materials and contamination strains. [Business description] Our company produces and sells “Pearl Green,” a cleaning agent for potable water tanks, for delivery to about 1,000 companies including building maintenance service providers and registered water tank cleaning companies throughout Japan. “Pearl Green” is made entirely of food additives and is a safe, high-quality and low-priced water tank cleaner. The entire process from procurement of raw materials through to production and sales is handled at our plant, which allows us to control the production quality and substantially reduce the costs so that we can offer the product at a low price. [Industry] Manufacturing and sales business [Strength of products/technologies] “Pearl Green” is made entirely of food additives and is a safe water tank cleaner. Since we can produce the cleaner in small lots at our own plant, we are able to quickly meet different requirements according to the customers’ working environments. We have also developed a new product based on the request from one of our customers. (We increased the viscosity of the existing “Pearl Green” and produce and sell the new sticky type suitable for ceilings and walls because it does not drip.) [Representative's message] We hope that the development, production and sales of new products will provide an opportunity to increase our market share to the top position. Our products are offered at a lower price than any other manufacturer’s products presently available on the market. We worked together with the Oita Industrial Research Institute and the Oita Industrial Creation Organization to develop a cleaning agent that is superior to any competing product. We listen carefully to our customers’ opinions and continue our research and development efforts to create new products. [Company structure for market development/overseas expansion] At present, we sell our products mainly to water tank cleaning service providers. However, we plan to open up new sales channels to small-sized food manufacturers. In addition, we will focus on the promotion of our foam cleaner and the development of new products to expand sales to water tank cleaning companies that are presently using our competitors’ products. [Market share/Ranking] We are ranked around 6th in terms of market share as our sales are approximately 20 million yen in the 150-million-yen market.
