Returning from a business trip to Peru

I arrived at Narita Airport after a two-week business trip to Peru.
We left Machu Picchu Station and traveled via Cusco, Lima, and Houston to Narita Airport, taking about 40 hours by train, car, and flight (three transfers). I felt a combination of jet lag and fatigue.

This was an extremely tough business trip, involving consultations with relevant organizations and local agents, long travel times, and a location with many ups and downs (10,000 steps a day, and the Apple Watch's floor count was 220). However, we were able to gather very useful information and build a cooperative system on-site, which allowed us to complete the mission without incident.

We will soon begin full-scale investigations of the Machu Picchu ruins using drones and other equipment. We will also attempt to discover new ruins. This will continue for about two years, and we will do our best.
