Write the experience clearly. Build the ideas into things.

A personal brand site focused on writing, software development, and exploring life in Japan. By turning long-form content and hands-on technical work into shared assets, I hope to connect with people who care about similar things and create practical, mutually useful collaborations. I also work with clients globally on software delivery and strategic product thinking with an international perspective.

Latest articles

From images to video, people seem to spend less and less time with written words. I still prefer writing as a way to organize my thoughts, and I hope some readers are willing to slow down and read through them. Donggui Xishi currently has 4 main topics: Japan Visas, Learning Japanese, Side Hustle Insights, and Working and Living in Japan. When I have ideas and time, I will keep updating these topics and adding new ones. You are welcome to come back anytime.

Ways to work together

Many things are hard to do well alone, but they can still be built together. Even in an age full of ideas like one-person companies and super individuals, I still believe it is difficult for a lone operator to sustain a business and serve clients well over the long term. You are welcome to talk about collaboration, and potential sponsors are also welcome to bring an idea and explore how we might turn it into something real.
