Musashi Philosophy


Shitsujitsu-Goken and Shisei-Ikkan defines the origin of Musashi. In other words, Simple and Sturdy and Consistent Sincerity.

“We have seen many companies rise and fall in history and I witnessed this in my own long life. We must not forget the fact that a group of people who were united in the spirit of Shitsujitsu-Goken and had the trait of Shisei-Ikkan rarely died out.”
                                                                                  - Founder, Yoshiharu Otsuka

Musashi Spirit

Customer First

“Customer First” requires us to see every aspect of our work from the customer’s point of view, and thereby ensure complete customer satisfaction when we complete the work. We will gain the trust of our customers by recognizing who they are, firmly grasping their real needs and expectations, and then responding to those needs swiftly.


We should be committed to doing our work wholeheartedly at all times, whilst being straightforward and honest in the way that we go about it. We should value our relationships with others, keeping to our promises and following all of the rules and regulations. We should not lie, cheat, or try to hide our mistakes. We should be willing to express our opinions and make our points honestly and politely.


We should never be satisfied with the current situation: we should always be thinking about, and trying out new creative ideas in order to improve our performance. As the world moves rapidly forwards: anyone who fails to keep up will be left behind: standing still is just the same as going backwards! This is applicable in every aspect of our business. Engineering, Research and Development, Manufacturing, Production Control, Management etc: every department must identify the real root causes of problems and endeavor to find ways to eliminate them.

Hard Work

“Hard work” means concentrating all of our effort into what we are doing and not giving up, compromising, or cutting corners until the task has been completed. Such effort also leads to our personal growth and development: by challenging and overcoming difficult problems and achieving our goals we experience a deep sense of achievement and satisfaction.

Cooperation for the common goal

“Cooperation for the common goal” is about combining the individual abilities of each player into the greater combined power of a united team. Monozukuri is a team game. We can overcome any kind of difficulty if every member of the world-wide Musashi Group is able to use their strengths and compensate for their weaknesses within a supportive team. The first requirement for any team is good communication, which enables everyone to share the common goal and understand one another. There is nothing stronger than a united, cohesive team dedicated to a common purpose.

Remember our rights and responsibilities

We should fulfil our own duties and also respect other people’s rights. Our actual rights and responsibilities depend on our particular roles and positions. Each of us should identify what our own responsibilities are and also ensure that we understand the rights of those around us.
