When someone makes agreements in Japan, such as when he/she rents a room, “Rentai-Hoshou-Nin” may be required.
“Rentai” means joint.
“Hoshou” means guarantee.
“Nin” means person.
And, “Rentai-Hoshou-Nin” means joint and several guarantor.
(Simple “Hoshou-Nin” means guarantor.)
There is a big problem with the term several, but I will explain it later.
When you are asked to become a “Rentai-Hoshou-Nin”, you should consider the situation very carefully.
By easily signing your friend’s house rental contract, you may bear grave responsibility beyond your expectation.
