South Korea will introduce tougher penalties for businesses that overcharge tourists in the accommodation and restaurant sectors starting next month, the finance ministry said Tuesday. The Cabinet approved revisions to the Enforcement Decree of the Tourism Promotion Act. The changes take effect Aug. 4, according to the Ministry of Finance and Economy.

Under the revised rules, operators of “hanok” stay businesses—traditional Korean houses—must post and follow official price lists. For the first violation involving overcharging or failing to comply with posted pricing, businesses face a five-day business suspension, rather than a warning under prior rules. The revisions also expand coverage to foreign tourist home-stay businesses in urban areas, which previously were not subject to requirements to post or comply with price lists.

The government previously implemented similar revisions for general accommodation businesses in mid-July. The new measure is part of efforts to strengthen consumer protection and promote tourism. Sources also indicate that repeat violations carry harsher sanctions, including longer business suspension periods for second and third breaches.
