At Japan's busiest airports, a flight may arrive or depart every two minutes or so. In spite of this, Japanese airlines are frequently ranked among the world's leading on-time flight operators.

The way a society deals with death, and how it pays tribute to those who have passed away, will tend to reveal a great deal about that society's values.

On this edition of Japanology Plus, we explore the past, present and future of graves.
