Today I planted several black pine trees, which I bought at a street stall on Ozosan. Ozosan is the shortened form of the word "Ojizosan", which means the days connected to "Jizo-bosatsu".
It is said that there will be special returns to the prayers offered on these days at temples. We usually call Jizo-bosatsu Ojizosan friendly. Jizo-bosatsu is a kind of god and is thought to relieve all living things in the world, from when Buddha has died until Miroku-bosatsu appears.
