I want to discover physical principles that will change the world.

“I was interested in “time” and scared of a space picture book I saw in my childhood”, Yukako Fujishiro said.
Until high school, she really wanted to create a “Time machine”. She found her true mission in life while taking a liberal arts course and decided to casually take a solar battery class. She said, "I want to discover a completely new physical principle and save humanity!" She chose to explore the universe in matter. Every day, she experimented with her new dreams.
