Our Head Office

Our head office is located in Marunouchi, the commercial center of Tokyo, and a mere 5-minute walk from JR Tokyo Station, with its train and bus connections to Tokyo Narita International Airport. In addition, there are five other metro stations connected to six different lines, rendering painless access to and from the rest of Tokyo. Our convenient location facilitates our emphasis on face-to-face discussions with clients whenever possible in order to ensure perfect communication. Moreover, we are only 15 minutes from the Japan Patent Office, so we are better positioned to arrange and conduct interviews with busy JPO examiners. Feel free to drop by our office when you are in Tokyo.
