Nickname (pen name)



Born in Fukuoka prefecture, living in Saitama prefecture

Family structure

  • 2018: Started dating and living with my wife
  • 2019: Married my wife
  • 2021: Started keeping a cat @ Munchkin (short-legged) ♂
  • 2022: First child (son) was born


I lived in Fukuoka prefecture from birth until college, and then moved to Tokyo when I started working.

I thought I would have a bit of an accent when I came to Tokyo, but surprisingly I switched to standard Japanese quickly, and I was surprised myself (lol)


  • Company employee (IT related)

I work as a system engineer at an IT company in Tokyo, and I handle multiple teams × multiple projects from planning to operation, doing a job like a PM for the entire development phase. I feel how difficult it is to move projects and people while rushing, but I’m very busy … I’m doing this blog as a breather (sweat)

What I’m into lately

  • Chinese language learning

I’m always grateful to the language school “Tian Tian Zhong Wen” that I introduced in this article. I take classes almost every day, but it’s really fun to learn new knowledge, and I dream of the day when I can communicate with Chinese people, and I keep working hard even though I’m busy.
