The South Korean government is imposing stronger entry restrictions on Japanese nationals entering the country, starting Monday.
The move, which comes immediately after Tokyo's stronger restrictions on South Koreans, includes a three-stage screening scheme.
It's also suspending visas and visa waivers for Japanese nationals.
Currently, Japanese visitors can stay in Korea for 90 days without visa.
Seoul says it will not issue visas for Japanese nationals unless they submit a health document which states whether they have any COVID-19 symptoms.
As of Monday midnight, the Japanese government also suspended the 90-day visa-free entry program for South Koreans, while adopting a 14-day self-quarantine for those flying in from South Korea.
This means South Koreans need to get visas in order to travel to Japan, which the Japanese embassy in Seoul explained would be time consuming.
Seoul described such move as "unfair and unscientific."
Japan is among more than one-hundred countries that have imposed curbs on travelers from South Korea.
Seoul's foreign ministry explained that so far, nearly 15-hundred South Koreans have been quarantined in countries, including China and Vietnam.
