The Leverage Shift is for owners of small and medium businesses, and for professionals, who want to use AI well without the hype. It explains what generative AI is, what the best research shows about its real gains and real limits, what an hour of an employee's work really costs in Japan, and what AI tools cost as of October 2026. Then it compares the two, task by task. The key idea: compare tasks, not people. AI multiplies good staff; it is not a reason to replace them.

- Part 3, Playbooks. Writing and email, customer service, marketing, sales and research, finance and admin, building websites and automations, translation, and using AI as a thinking partner.
- Part 4, Use It Safely. When AI gets it wrong, privacy and security, the rules in Japan, the EU and beyond as of 2026, and leading your people through the change.
