What I wish was different
I think it would have helped if I was able to share my progress and acquired feedback more frequently from the core team and/or other members of the team. A diversity in feedback would have been very helpful. Another downside of the project, which I think was exacerbated further by the "vagueness" of instruction in Japanese working culture, is the lack of more specific, concrete deliverables. I was given a lot of abstract instructions and most of them were only derivatives of the company philosophy. While it was helpful to know the purpose of the organization well, I had to navigate and translate those concepts to something actionable by myself.
