SEKISUI symbol comprises

Our company symbol comprises the three S's of the company's original name, adopted at the time of its foundation, "SEKISUI SANGYO" enclosed in a hexagonal shape resembling a tortoise shell (the chemical symbol for benzene), symbolizing the Chinese character meaning "water."
In November 1959, this mark was defined as the "3S Principle" and formally established as the company creed.
"The difference between people living their lives in accordance with ideals and those simply going where the currents and eddies of life take them becomes ever more apparent as the long years of their lives pass. The same is true of business. Only when employees mass under a common ideal arising from a basic policy of business management can the company demonstrate its great power as a corporate community."
It was in the spirit of this intent that the 3S Principle comprising Service, Speed and Superiority was established as the motto of SEKISUI.

Origin of our Company Name

The term "SEKISUI" is derived from Sun Tzu's The Art of War, an ancient Chinese classic.

The Onrush of a conquering force is like the bursting of pent-up waters into a chasm a thousand fathoms deep.

Sun Tzu states:
"The victor of a battle is determined in one fell swoop with tremendous force, just as pent-up water [SEKISUI] drops into a deep gorge.
And before the battle, he must position himself for victory."
Adaption of this concept into corporate activities:
Expanding business activities will inevitably encounter problems and challenges.
To overcome them, it is important to gain a full understanding of and analyze your opponent's situation, to consolidate your own structure, and release the power of pent-up waters to be victorious in battle.
