The symbol of the Salesian Polytechnic is based on three elements: the cross, light and stars.

The cross symbolizes our position as a Catholic mission college in Japan, providing an education based on the "Preventive System of Education" of Don Bosco, founder of the Salesian Society.

Light comes from the description of creation in Genesis: "God said, ‘Let there be light,' and there was light. And God saw it and it was good." Light is the first thing that God created, a wonderful thing indeed. What comes to mind when you hear the word "light"? Brightness, hope, dreams, love, future, warmth, the sun, happiness, youth, life…. God saw the light and said that it was good. Our hope and prayer is that all Salesian Polytechnic graduates will go on to become shining beacons of light in society, living lives that are good in the eyes of God and of society.

The three stars symbolize our three mottos: Loving Kindness, Human Technology and Living Truth. They are shown rising into the endless sky, just as our students and staff constantly look upward, facing challenges, growing and developing. Stars delight the eye, guide the voyager across desert or sea, and comfort the sorrowing. Starlight, unlike the burning light of the sun, is something we can all aspire to. We pray that our instructors, our students and our graduates will all place great importance on their personal development, striving to become stars that illuminate society.

The school color, blue, is the blue of youth. As well as studying, we hope our students will enjoy the precious years of their youth, participating in the many sports programs, extracurricular activities and events like the Ikuei Festival and the Robocon. This is the distinctive feature of youth - a delight in tackling each challenge as it presents itself.
