This week we wrap up the Japanese-learning experiment by our US entrepreneur recently arrived in Japan, TP. Clearly his is not the only program that works in learning the language, but for those of us who are naturally language challenged and who didn't do a year of high-school here as a teenager, it's a course that can work. TP wraps up by making some observations about what it really takes to get the job done, and about mistakes made and lessons learned.
