about birchill

Founded in June 2019 in Tokyo, Japan by current and former Web browser developers, we continue to build the Web from Asia.

Our company name and logo comes from the image of white birch trees on a hill. Birch trees in Japan are said to represent light, abundance, patience, and kindness. Through our deep experience we seek to be a calm and mature presence in an industry of rapid change.
