Tom ToTom To

Tom To was born on December 25, 1987, and serves as the drummer of Mr. When the band first debuted, he was still working part-time delivering sashimi; he soon left the part-time job to devote himself fully to the band.

After the band's contract with its record company ended, Tom To ran a business with friends and offered drumming classes. He later opened a music classroom offering acoustic guitar, drum set, children's, electric guitar, and bass guitar classes, while personally teaching mainly drums and guitar to children.

To improve his music teaching methods, Tom To took a U.S. distance-learning course and drew on a friend's experience researching child psychology and education at university to begin developing a three-step learning curriculum.

The decision to reunite as a four-member lineup was connected to the members' support for one another. After Desmond Tam wrote the members a long message explaining his idea of organizing a concert, Tom To responded, "He wrote a thousand-word message. We're brothers, so whatever he does, we'll definitely support him—all the more so when we're making music together. The most important thing is that we work well together."
