That portable shrine is called Mikoshi.
It is usually stored in local storage.
You can see Mikoshi especially in summer or autumn season because there are Shinto festival of local big shrines.
(Small shrines don't have own Mikoshi)
Most Japanese festivals are called Matsuri but Shinto's meaning is different.
It is a sacred ritual originally not just for funny event.
First of all, local people put Mikoshi in front of a shrine,
and local nature god worshiped in the shrine rides on it.
By carrying Mikoshi around a town,local people and the town are purified and protected.
By the way, Matsuru is important verb in Japan.
It means two but unseparetable one.
1, Worship/Believe/Respect/In awe of invisible sacredness
and
2, Taking care of/Look after them
1 plus 2 = Matsuru
Matsuri by Saburo Kitajima
This song and the singer is well known in Japan.
People want to listen the song in the end of year.
Interesting thing is most Japanese people, he and music creators of this song are not reverent Shinto believer. (I think)
We don't have special education or teaching book.
But everybody knows what the song is meaning.
Shinto mind is deeply rooted in Japanese people without knowledge about Shinto.
This song is especially for men.
I'm sure all men like this song even if you are not Japanese.
