South Korea is introducing new signs for its hot spring spas to remove any confusion for those seeking other kinds of steamy liaisons.The Ministry of Public Administration and Security introduced the new blue logo Monday for about 480 spas across the country, said ministry official Lim Jae-wung. The sign replaces a nearly century-old red icon - a circle with rising wisps of steam that have been appropriated by "love motels," which offer prostitution or short stays for couples having extramarital relations.

Public baths and many lodging facilities also use the old logo, which was introduced when South Korea was colonized by Japan from 1910-45, Lim said.

The new logo depicts waves of water with two circles symbolizing the heads of a father and son amid rising steam. Those using the sign at non-spa facilities can be punished by up to two years in jail and a fine of up to $10,030, Lim said.
