...an end. Now I can finish this travel serie. I really enjoyed that stay in Japan after a 3 years break. For this reason, it was of course hard and painful to leave.Anyway... "Cruise Flight Level Climb" is engaged since a few minutes. So: no step backwards available.「To Infinity, and beyond!」。Or「Back to the Future」。I'm really thankful to all japanese people who did their best to ease my stay and travel this time. I will be in debt for the rest of my life.I could notice many changes since my previous trip. COVID-19 related, or not. Some digital leap, new equipments and behavior changes.Greenland at night was a real pleasure to my eyes, though I was somehow sad.Not only Greenland. Scotland in the morning was also so beautiful. In fact, Earth is beautiful.After this experience, I decided to stop professional activities ASAP, so I will be able to travel with less constraints. But now is the time for "outside Japan pictures". I hope you'll enjoy. いつもありがとう。
