1.
portable shrine
A decorated miniature shrine carried on poles by a group of people during festivals. It is believed to house the spirit of a deity during the procession.
Usage
The core verb collocation is 神輿を担ぐ (to carry a mikoshi on one's shoulders). The figurative idiom 神輿を担ぐ can also mean to put someone forward as a figurehead or leader.
Cultural note
Portable shrines are central to many Japanese festivals (祭り). Carriers shout わっしょい as they parade the shrine through the streets. The shrine temporarily houses the local deity (氏神) during the festival.
