Tokyo Electric Power Shares Fall 1.2% as Typhoon Dujuan Cuts 58,000 Homes’ Power

Typhoon Dujuan swept across Japan on September 21-22, killing at least six people and leaving approximately 58,000 households without power in Chiba Prefecture, a core service region for Tokyo Electric Power (TEPCO, 9501.T). The utility’s stock fell 1.2% to 549.7 yen on September 22 as investors assessed recovery costs and operational disruptions. Oshima island recorded 832 millimetres of rain over 48 hours, more than double its September average, triggering widespread landslides and flooding.

Typhoon brings record rainfall and widespread outages

Typhoon Dujuan, the region’s 25th typhoon this year, tracked northeast along Japan’s Pacific coast on September 21, dumping record rainfall across multiple prefectures. Oshima recorded 832 millimetres of rain over 48 hours. Tokyo’s Edogawa Ward reached 282.5 millimetres in 24 hours, a record. The intense precipitation triggered landslides in Kanagawa and Chiba prefectures, killing at least six people and leaving four others missing.

Power outages affect 58,000 TEPCO customers in Chiba

As of Tuesday morning September 22, approximately 58,000 households in Chiba Prefecture remained without electricity following the typhoon’s passage. Intense rain inundated houses and temporarily cut off electricity to the region. TEPCO crews began restoration work, though landslides and flooding complicated access to damaged infrastructure and delayed repairs across the prefecture.

TEPCO stock declines amid recovery uncertainty

TEPCO shares fell 1.2% to 549.7 yen on September 22, reflecting investor concern over operational disruptions and recovery costs. The utility carries a debt-to-equity ratio of 1.98 and faces significant capital expenditure demands. Meyka rates the stock a B with a 12-month forecast of 713.50 yen, suggesting limited upside from current levels as the company absorbs disaster-related expenses and restoration efforts.

Evacuation orders affect nearly 2 million as typhoon weakens

Evacuation warnings were issued for almost two million people across the Kanto region. The typhoon moved offshore by Tuesday morning, allowing authorities to lift or downgrade most heavy rain and landslide warnings. Wind speeds had dropped to 143 kilometres per hour with gusts of 198 kilometres per hour as the system tracked away from Japan into the Pacific.

Final Thoughts

TEPCO’s 1.2% decline reflects near-term uncertainty over restoration timelines and costs. With Meyka grading the stock a B and forecasting 713.50 yen, the utility faces pressure from both operational disruption and elevated debt levels as it mobilizes resources to restore power across Chiba.
