SEOUL (REUTERS) - Calls in South Korea for a boycott of Japanese goods in response to Japanese restrictions on the export of high-tech material to South Korea picked up this week, as a dispute over compensation for forced wartime labour roiled ties between the United States allies.
The dispute is the latest flashpoint in a relationship long over-shadowed by South Korean resentment of Japan's 1910-1945 occupation of the Korean peninsula, in particular South Korean "comfort women", a Japanese euphemism for women forced to work in Japanese military brothels before and during World War II.
The latest bitterness over forced labour could disrupt global supplies of memory chips and smartphones. Samsung Electronics Co and SK Hynix Inc - the world's top memory-chip makers, and suppliers to Apple and China's Huawei Technologies - could face delays.
"A boycott is the most immediate way for citizens to express their anger," said Choi Gae-yeon of the activist group Movement for One Korea, that staged protests in front of a Japanese car dealership and a retailer in Seoul this week.
"Many people are angry at the attitude of the Japanese government."
The row over forced labour exploded last year when a South Korean court ordered Japan's Nippon Steel & Sumitomo Metal Corp and Mitsubishi Heavy Industries to pay hundreds of thousands of dollars to South Korean plaintiffs.
Japan maintains that the issue of forced labour was fully settled in 1965 when the two countries restored diplomatic ties, and has denounced the ruling as "unthinkable".
Japan said on Monday (July 1) that it would tighten restrictions on the export of high-tech materials used in smartphone displays and chips to South Korea in connection with the dispute.
The restrictions came into effect on Thursday, fuelling calls for retaliation in South Korea.
By Friday, nearly 25,000 people had signed a petition posted on the South Korean presidential office website calling for a boycott of Japanese products and for tourists not to visit.
The government must respond to a petition that gets 200,000 signatures in a month.
Some Korean social media users posted "Boycott Japan" messages and shared a link to a list of Japanese brands that could be boycotted, including Toyota Motor and Fast Retailing's Uniqlo.
Toyota's South Korean unit and Fast Retailing's South Korean unit did not have an immediate comment.
"Japan boycott movement" was among the most searched-for terms on South Korea's main online search engine Naver.
On Thursday, a South Korean actor deleted photographs he posted on social media of a visit he made to Japan after online criticism.
Shares linked to tourism fell on the South Korean market this week due to concern about prospects for travel to Japan.
Shares in South Korea's biggest tour agency, Hana Tour, fell 3.4 per cent on Thursday before paring losses on Friday.
South Korea imported US$54.6 billion (S$74 billion) worth of goods from Japan in 2018, while also paying for US$11.5 billion worth of its services.
South Korea exported US$30.5 billion in goods and US$8.7 billion in services to Japan in the same year, according to South Korean customs and central bank data.
