Red Stamps （御朱印）
One of my hobbies is collecting Red Stamps.
I tell you about it.
Red Stamps are like the signatures of shrines or temples.
Usually, people who collect the Red Stamps prepare the Red Stamp book, which they can buy at any shrine or temple.
They find the Red Stamp windows in the shrines or temples.
They pay about 500yen, then wait a second while a person stamps the book and write some special message and the date.
How do you use such Red Stamp book?
Family members put those stamp books in the coffins with the people who collect them,
Collecting Red Stamps is really a holy hobby, I think.
