Stand in the shoes of others and engage in dialogue with empathy
At all times, we will never forget to be considerate of others. By always putting ourselves in the shoes of others, we will build relationships of mutual trust through ongoing dialogue based on empathy and consideration.
Have self-awareness and seek constant self-improvement
Growth is possible at any age.
To achieve personal growth, we must consider what we can do for the society in which we live, first looking carefully at ourselves and continuing to pursue self-improvement to achieve even greater heights.
Pursue quality and value that goes one step ahead
We will continue pursuing quality and value one step ahead of the rest: this is our DNA.

Expand curiosity and transform awareness into action
Going beyond our own specialized fields, we will keep our sense of curiosity alive, connecting the insights and ideas we gain from this curiosity to the actions we take.
Create synergies by bringing unique personalities together
Each individual among us brings different strengths to the table.
By respecting talents and personalities that differ from our own, and by proactively multiplying each other's strengths, we will create innovative synergies.
Look ahead to the future, continuously challenging ourselves
We will not only respond to the voices of our customers and the changing times, but also recognize current trends and create new value that is not merely an extension of what we have provided in the past.
Moreover, we will continue to take on the never-ending challenge of creating products and services that engender both inspiration and excitement.
