In Japanese education, there is morality as a guidepost for how to live as a person. Children learn courtesy and gratitude towards others inherited from their parents and school since childhood. The once-in-a-lifetime chance is one of them. This word also has a deep meaning.
I'm an expat viewer from US and subscribed to your channel recently after your site popped up as recommended channel. Your interviews are satisfying in that it's usually much longer than the most of similar programs. That means you can get a little deeper into what all these travelers are into and why Japan was chosen for their destination. This time it was no different and I found their experience very interesting as well as your varied questions. Keep up the good work !!!
