Our Story
OSUNO – DESIRE TO HONOR VIETNAMESE TECHNOLOGY
The Chairman of OSUNO, Mr. Do Manh Hai, is a young man passionate about technology, comes from the motorcycle business. With nearly 20 years of experience in the profession, he has always cherished the dream of bringing technology products from Vietnam to the world. However, in 2012, during the economic downturn, he faced an important decision in his career.
He realized that if he continued to stay in the locality, where people mainly lived by rice farming and the economy was not yet developed, he could never realize his dream. Therefore, he decided to invest in development in major cities of Vietnam such as Hanoi, Da Nang, Ho Chi Minh City… And a new journey of OSUNO begins here!
Japan is considered the cradle of high-quality products. Especially in the industrial and high-tech equipment fields. Japanese products are often thoroughly inspected and tested to ensure the best quality. Because he was so impressed by the quality of Japanese products and service culture, Mr. Do Manh Hai decided to choose the name OSUNO, which is the pride and the source of the quintessence. Later, when working with the product research team, Mr. Do Manh Hai was once again convinced by Japanese technology and decided to choose Japanese technology for his factory.
