While providing services regarding all the marketing and advertising needs as a freelancer Toshi Ichikawa since March 2018, I noticed that there were various needs for me to help brands for their business success. With the company entity registration, I am sure that I can help more businesses. This is the background of my transit to Tetra Tokyo G.K.

From the localization to Japanese copywriting and full branding and even business supports, I am here in Tokyo to help you. Contact me anytime.
