In October 2017, we moved to Roppongi's landmark Tokyo Midtown. Not only is it an excellent location, but the interior of our office is designed to completely maximize our operational efficiency. Naturally, our engineers, corporate staff, and back office employees all enjoy high spec PCs with large monitors. The chairs used in our office were selected by polling our employees. As for keyboards, graphics tablets, and software, each employee is allowed to choose which specific ones they want to use.
