Our Corporate Culture

  • Conservative
  • Cooperative
  • Team Work
We are a small team of 28 that includes our founding members. Together, we've cultivated a work environment that is truly warm and family-like. Throughout the stages of development, there is great deal of communication that occurs between members, making our work place a very lively one. On the other hand, being a small team, as members gain experience their duties and responsibilities deepen, therefore we expect our employees to be committed to their work and pursue excellence. Our company encourages employees to take Premium Friday (a campaign initiated by the Japanese government to take the afternoon off on the last Friday of the month), by which members often use as an opportunity to spend time together outside of work, and get to know each other better. We also have an all-you-can-eat sweets corner at the office, where members can take a break during the day.
