SMASH Group will have 50th anniversary in 2028. We have always walked together with our clients by meeting (≒ Smash) the "connection" that has been nurtured as a corporate culture. On the other hand, in the future, everything will be connected to IT, the world will be overflowing with information, and the world will be filled with uncertainty.
