OSUNO STORY

OSUNO – A PASSION TO HONOR VIETNAMESE TECHNOLOGY

The Chairman of OSUNO, Mr. Đỗ Mạnh Hải, is a passionate engineer who began his career in the motorcycle business. With nearly 20 years of experience, he has always carried the dream of bringing Vietnamese technology products to the world. In 2012, during a period of economic downturn, he faced one of the most important decisions of his career.

He realized that staying in his hometown – where most people still relied on rice farming and the economy was underdeveloped – would not allow him to achieve his dream. Determined to move forward, he chose to invest and develop in Vietnam’s major cities such as Hanoi, Da Nang, and Ho Chi Minh City. From there, a new journey for OSUNO began!

Japan has long been known as the cradle of world-class quality products, especially in the fields of industry and advanced technology. Japanese products are renowned for their strict testing, reliability, and excellence. Deeply impressed by this quality and service culture, Mr. Hải chose the name OSUNO – a symbol of pride and a tribute to the finest values. Later, while working alongside his product research team, he was once again inspired by Japanese technology. This led him to make a pivotal decision: to adopt Japanese technology standards for OSUNO’s own manufacturing facilities.
