Bundang: When Lee Kyung Eon and her friend recently scrapped plans to go to Japan for summer vacation, they paid a 135 penalty for canceling their plane tickets, joining a growing campaign in South Korea to boycott Japanese goods and services. “We intended to do something that doesn’t help Japan, even (it’s only) a little thing,” said Lee, a 26-year-old office worker in Bundang city, just south of Seoul. “Many people told us we did something really good.” A widespread anti-Japan boycott has gained ground in South Korea since Tokyo on July 1 tightened control of exports of three chemicals used to manufacture semiconductors and display screens key export items for South Korea. The boycott could worsen as Japan is expected to expand its export curbs to other materials as early as Friday by removing South Korea from a list of countries granted preferential trade status.

Two men in their 70s have set themselves on fire in an apparent protest against Japan. One died and the other, who set himself ablaze on Thursday, remained in critical condition. South Korea accuses Japan of retaliating over local court rulings last year that ordered two Japanese companies to pay compensation to former Korean employees for forced labor during Tokyo’s 1910-45 colonization of the Korean Peninsula. Japan has denied that, saying its action was taken out of national security concerns.

They worry the boycott could only aggravate the animosities as it may trigger a backlash from Japan. But others say the campaign exposes the bitter resentments many South Koreans still harbor against their former colonial ruler. A recent survey suggested 80% of South Koreans are reluctant to buy Japanese products. Angry South Koreans have taken to Instagram and other social media, posting videos on their canceled Japan-bound plane tickets, sharing information on which Japanese companies operate in South Korea and expressing their support for the boycott. There have been some consequences. HanaTour, the largest travel company in South Korea, said a daily number of reservations for Japan trips has dropped to about 400-500 from 1,000-1,200 late last month. Other tour agencies have reported similar or lower booking figures for Japan tours. Last year, about 7.5 million South Koreans visited Japan, making it the most popular destination. The state-run Korea Tourism Organization said it has no data on how many South Koreans traveled to Japan this month. At hypermarkets and 24-hour convenience stores, the sales of Japanese beer have nosedived. Beer is the most popular among Japanese products. For example, at E-mart, the largest retailer in South Korea, the sales of Japanese beer from July 1-24 declined by about 38% from a month ago.
