Foreign residents in Japan are witnessing significant shifts in the country's economic landscape this week, from falling gasoline prices to major corporate restructuring and currency fluctuations that could affect daily living costs and investment decisions. Taiwan Semiconductor Manufacturing Company (TSMC), a major player in Japan's technology sector with facilities in Kumamoto, reported record-breaking financial results for 2025. According to NHK, the world's largest contract chipmaker achieved its highest-ever revenue and net profit for the second consecutive year, driven primarily by sustained demand for AI-related semiconductors. This performance underscores Japan's growing importance as a semiconductor manufacturing hub and suggests continued investment and employment opportunities in the tech sector for skilled foreign workers. For expats concerned about transportation costs, there's welcome news at the pump. The Petroleum Information Center, commissioned by the Japanese government, reported that regular gasoline prices fell to 155.1 yen per liter as of January 13, marking the ninth consecutive week of price declines with a 0.6 yen drop from the previous week. This downward trend provides some relief for foreign residents who drive, particularly those in rural areas where public transportation options are limited. Japan's stock market experienced volatility on January 15, with the Nikkei average declining as investors took profits on semiconductor-related stocks that had recently surged. According to NHK, this sell-off centered on chip sector shares, reflecting global market uncertainties. Foreign residents with investment portfolios in Japanese equities should monitor these fluctuations, particularly if they hold technology sector positions. Currency markets also saw notable movement, with the yen appreciating against the dollar on January 15 amid concerns about potential government and Bank of Japan intervention. This strengthening yen could benefit expats sending money overseas or planning international travel, as their yen holdings gain purchasing power abroad. However, those receiving income in foreign currencies may see reduced yen equivalents. The beverage industry is undergoing significant changes that will affect consumer choices. Kirin Beer announced plans to reformulate its flagship "third beer" product category into actual beer within 2026, responding to this year's liquor tax reforms that reduce taxes on beer. This shift reflects broader industry trends, as competitors also pivot toward beer sales under the new tax structure. Expats may notice changes in product lineups and potentially different pricing at their local convenience stores and supermarkets. Asahi Group Holdings reported a substantial 20% decline in beer business sales for December compared to the previous year, attributed to ongoing system disruptions from a cyberattack. This incident highlights the vulnerability of major corporations to digital threats and may result in continued product availability issues in the short term. Inflation remains a concern for household budgets. Japan's corporate goods price index for 2025 rose 3.2% year-on-year, driven significantly by rice price increases. According to NHK, these wholesale price pressures typically filter down to consumer prices, meaning expats should anticipate continued upward pressure on grocery costs, particularly for rice and rice-based products. In transportation news, JR West stated it cannot accept proposed increases to shinkansen leasing fees being considered by the Ministry of Land, Infrastructure, Transport and Tourism. JR East has taken a similar stance. While these negotiations primarily affect railway operators, any fee increases could eventually translate to higher ticket prices for the bullet train services many expats rely on for business and leisure travel. Meanwhile, Toyota Group announced it will proceed with a tender offer for Toyoda Automatic Loom Works starting January 15, raising the purchase price from initial plans to a total value of 4.3 trillion yen. This massive delisting represents one of Japan's largest corporate restructurings and reflects the Toyota Group's strategy to consolidate operations away from public market scrutiny. These developments paint a complex economic picture for Japan's foreign residents, with falling fuel costs offset by persistent inflation in food prices and ongoing corporate sector adjustments that may affect employment and investment opportunities in the months ahead.
