In Korea, the term skinship is used to describe the act of intimate, non-sexual touching between very close (Usually same-sex, but can include both genders.) platonic friends. It involves acts such as holding hands/arms, hugging, and kissing on the cheeks.

Sometimes it goes even deeper than that and can even involve bathing together, as Koreans (And the Japanese) believe that group nudity helps break down the barriers and helps establish a closer relationship.

[Britney]

A concept originating in Japan, whereas social interactions and dealings were considered more intimate and relaxed when they took place within a communal onsen, or public bath.
This concept is still in some practice today, as when a business agent will meet a potential client for dinner, or drinks, or on a racquetball court.
It has also evolved to define a situation of intimacy derived from the touch of skin, or close proximity thereof, as in a mother and child bonding from birth.
In Korea, as well as some other places, it has come to also mean sexual contact, heavy petting, and related activities.
