Why Mizuno Marine—35 years since founding—
continues to be trusted and chosen

• STRENGTH 01

  

  Total maintenance made possible
  because we know vessels and
  marine services inside and out

  For more than 35 years since our founding, Mizuno Marine has provided a wide range of marine support, including marine engine sales and servicing, parts supply, and the provision of specialized equipment such as tsunami shelters and lifeboats.
  In 2025, we newly established Himeji Shipyard / Himeji Branch Service Center (Okumura Shipbuilding Industry Co., Ltd.) and developed infrastructure capable of handling repairs for 100-ton-class vessels.
  With a structure that supports stable operation and maintenance management for both individuals and corporations, we have earned trust from customers nationwide.

• STRENGTH 02

  

  Fast response—stock parts can arrive as soon as the next day after ordering!

  To meet customer needs for rapid procurement of engines and parts, Mizuno Marine focuses on maintaining robust domestic inventory. We keep many genuine OEM parts from major manufacturers in stock, and in-stock items can be delivered as early as the next day (*excluding some regions and depending on weather conditions, etc.). Taking advantage of our location close to the airport, we achieve both fast response and stable supply. We have also built a structure that can respond to urgent troubleshooting.
  We have earned strong trust from marinas, maintenance providers, and corporate customers nationwide.

• STRENGTH 03

  

  ISO9001 certified! Thorough quality control based on our own standards as well

  Mizuno Marine acquired the international quality management standard “ISO9001” in 2010 and has maintained and operated a stable quality management system for more than 10 years since then.From parts purchasing to inventory control and shipping, we practice ISO-compliant processes at every step.
  In addition, because we handle highly specialized products such as vessels and marine engines, we have introduced our own inspection and check framework.
  By strengthening standards for condition checks and functional inspections, skilled staff carefully verify each item one by one. This enables highly reliable parts supply that customers can use with confidence.
