Ask HN: How to start an AI-oriented consulting company in Tokyo?

I've been living in Tokyo for a little over a year and a half on a work visa and have noticed there is a significant shortage of investment in in-house software development at traditional Japanese companies. There is an even bigger shortage of talent in AI. Japanese companies typically outsource software development to smaller companies within Japan or companies overseas. These consulting and outsourcing companies are often started by someone who previously worked at a place like Amazon, Softbank, Google, etc and become quite successful, sometimes with business models of simply reselling cloud services from Google or AWS. After hearing about these people breaking into the market and becoming successful, I thought it would make sense to give it a try myself. I have a background of 3 years combined at Amazon.com and AWS in the US as an SDE, and have been in my current role as senior engineer in AI at a big Japanese company for 1.5 years doing humanoid robotics development. I'd be particularly interested in helping Japanese companies identify and introduce automation and AI into various parts of their business. Any guidance would be greatly appreciated!
