Arctic Air Surge Drives Severe Cold Wave and Widespread Advisories Across Korea
Jan. 21, 2026 | Environment

A powerful high‐pressure system near the Bering Sea is channeling frigid Arctic air into the Korean Peninsula, triggering a severe cold wave across the country.

**A blocking pattern set up by this high‐pressure system has stalled a low‐pressure area over South Korea, continuously funneling Arctic air southward.**
This configuration has driven rapid temperature drops nationwide and is expected to maintain subzero conditions through the end of the month.

**Cold wave advisories cover Seoul, its metropolitan area, the Chungcheong region, North Gyeongsang Province, and parts of North and South Jeolla provinces.**
Cold wave warnings will take effect at 9 p.m. local time in northern Gyeonggi Province and central and northern Gangwon Province.

**Tuesday morning’s lows reached minus 13 °C in Seoul, minus 12.8 °C in Incheon, minus 21.2 °C in Yanggu, and minus 2 °C in Busan.**
Forecasters predict Wednesday’s temperatures could dip to minus 15 °C in northern Gyeonggi and Gangwon’s highlands, with southern areas falling between minus 10 °C and minus 5 °C. Daily highs are expected to range from minus 4 °C to plus 7 °C, leaving many inland regions below freezing. Although a slight warming trend may begin Sunday and last through January 28, temperatures will remain below seasonal averages.

**Snowfall of 2 to 7 centimeters is expected along the western coast of Jeolla from Thursday through Saturday, with mountainous areas of Jeju Island receiving 5 to 10 centimeters.**
Eastern coastal areas recorded under 1 centimeter of snow Tuesday morning, and additional snow will fall along the South Chungcheong and Jeolla coasts and on Jeju Island. Snowfall will intensify Wednesday and Thursday along the southwestern coast, on Jeju, and on the islands of Ulleung and Dokdo.

**The Korea Disease Control and Prevention Agency monitors cold-related illnesses through an emergency room surveillance system covering 512 medical institutions nationwide.**
From the 2020–2021 to the 2024–2025 seasons, the system logged 1,914 cases, 56 percent involving people aged 60 and above—including 234 patients with dementia. Older adults experienced more instances of hypothermia, while younger individuals more often suffered frostbite and chilblains. Across all age groups, most incidents occurred on roads; elderly patients were more likely to fall ill near or inside homes, whereas younger people were more affected at outdoor recreation sites such as mountains, ski resorts, and riversides.
SK Telecom Files Lawsuit Challenging Record Fine Over Massive Data Breach
Jan. 21, 2026 | Governance & Law

SK Telecom is contesting a record 134.8 billion won fine imposed for a massive customer data breach.

**On January 19, 2026, SK Telecom filed an administrative lawsuit at the Seoul Administrative Court, challenging the Personal Information Protection Commission’s 134.8 billion won penalty for a breach that exposed personal data of roughly 23 million customers.**
Represented by Kim & Chang, the company submitted its complaint just before the 90-day appeal deadline and said it will accept the court’s ruling once delivered.

**The PIPC’s fine followed its probe of a hacking incident confirmed in August 2025, when attackers accessed 25 categories of data—including phone numbers, IMSI codes, and USIM authentication keys.**
At 134.8 billion won, this sanction is the largest the PIPC has levied since its 2020 founding, surpassing the combined 100 billion won penalties imposed on Google and Meta in 2022. Regulators issued the fine about four months after SK Telecom publicly disclosed the breach.

**In response, SK Telecom has invested 1.2 trillion won in victim compensation and security upgrades.**
The company offered free USIM replacements to all affected subscribers, discounted monthly bills, and 50 gigabytes of complimentary data through the end of 2025. SK Telecom reports no confirmed cases of direct financial harm to customers stemming from the leak.

**SK Telecom’s lawsuit centers on the PIPC’s penalty calculation, arguing that regulators failed to distinguish this external hacking attack from cases of unauthorized data collection for commercial gain, and that they did not adequately account for the company’s substantial remedial measures or the absence of consumer losses.**
If the court finds procedural errors in the commission’s methodology, the PIPC would need to recalculate and reissue the fine, potentially bringing it below 100 billion won. SK Telecom has requested a comprehensive judicial review on those grounds.

**Meanwhile, a consumer protection agency has ordered SK Telecom to pay 100,000 won per affected user, and a state mediation panel has advised compensation of 300,000 won per complainant.**
Reports also indicate that LG Uplus suffered a cyberattack following similar breaches at SK Telecom and KT, and government probes are underway into alleged attempts to sell SK Telecom customer data.

Japan even produces Dokdo merchandise and sells it to tourists

Hankyung | Local Language | News | Jan. 21, 2026 | Geopolitical Conflict and Disputes

Japan is escalating its sovereignty claims over Dokdo by selling various Dokdo-themed merchandise on Oki Island, Shimane Prefecture, a location described as a strategic base for Japan’s efforts to assert control over the islets. Items like sake cups, T-shirts, and badges bearing Dokdo motifs are openly sold at tourist spots including a shop inside the Oki Island passenger terminal, without restrictions.

Oki Island has also hosted rallies promoting Japan’s claim to Dokdo and installed related billboards. Since 2016, the Gumi Takeshima History Museum on the island has displayed testimonies and materials aimed at validating Japan’s sovereignty over Dokdo to local residents. Additionally, Japan has used symbolic gestures such as involving Oki Island in the Tokyo Olympics torch relay route to further its claims.

The continuous promotion of Dokdo as Japanese territory through public displays and merchandise is viewed as a tactic to normalize this perception among tourists. South Korean experts emphasize the need for a more concrete and systematic response strategy to counter these sustained Japanese efforts to assert sovereignty over the disputed islets.

Nearly 4 in 10 firms participating in RE100 initiative face difficulties in sourcing renewable power

Yonhap | English | News | Jan. 21, 2026 | Supply Chain Issues

Nearly 40 percent of South Korean companies participating in the global Renewable Energy 100 percent (RE100) initiative are facing difficulties in sourcing renewable energy due to high costs and limited procurement options. Among 183 South Korean firms involved, 70 reported challenges in securing enough renewable energy to power all their operations with 100 percent renewable electricity in 2024, showing an 80 percent increase from 39 companies in 2022.

The main obstacles cited are the cost burdens and lack of available procurement mechanisms. Compared to other major economies, South Korea's figure is significantly higher, with the United States reporting 20 companies, China 29, and Japan 48 facing similar issues in 2024.

In response, the Federation of Korean Industries (FKI) has recommended 20 policy agenda items to the government, aiming to support companies in the RE100 initiative. These include financial incentives for firms that directly purchase renewable electricity from power producers. The FKI emphasized the need to improve systems and policy support to help Korean companies remain internationally competitive while securing renewable energy.

Gov't to provide temporary tax benefits to investors investing back home

Yonhap | English | News | Jan. 21, 2026 | UndeterminedTaxes

The South Korean government will introduce a temporary tax incentive in 2026 for retail investors who sell overseas stocks and reinvest the proceeds in domestic assets. Investors who convert the proceeds into Korean won and invest domestically for at least one year will be eligible for an income deduction on capital gains from overseas stock sales, which are currently taxed at 20 percent. The tax exemption is capped at 50 million won (approximately US$33,900) per person, with the deductible amount varying by the timing of the sale: 100 percent for sales in the first quarter, 80 percent in the second quarter, and 50 percent in the second half of 2026.

Additionally, a special tax benefit will be offered to retail investors investing in currency-hedged products, allowing a deduction of 5 percent of the investment amount from overseas stock capital gains, up to a cap of 5 million won per person. These measures are part of a broader package aimed at curbing continued net capital outflows by domestic investors, which have contributed to the depreciation of the Korean won against the U.S. dollar.
