Will Super Typhoon Dolphin hit Japan?

Prediction markets put the probability at 80%: Will Super Typhoon Dolphin hit Japan. Currently, markets see this as likely (80% YES).

What’s Happening

Super Typhoon Dolphin, a powerful storm named after Hong Kong’s Chinese white dolphins, has intensified to **Category 5 strength** in the northwestern Pacific as of **July 30, 2026**, according to the Yale Climate Connections. The storm was located more than **620 miles (1,000 km) south of Tokyo** on that date, with the Joint Typhoon Warning Center (JTWC) forecasting it to approach the sparsely populated **Ogasawara Islands** as a **Category 3** system by Monday. Forecast models indicate the super typhoon will track west-northwest, potentially reaching seas near **Minami-Torishima Island** by Sunday before moving toward the Ogasawara chain, while its outer subsiding airstream is expected to bring very hot conditions to coastal southeastern China, Hong Kong, and South Korea in the latter part of next week [Yale Climate Connections, Jul 30].

The storm’s trajectory has shifted toward Japan, with the Japan Meteorological Agency urging residents of **Okinawa Island** to prepare for severe weather before an expected landfall this week. As of **August 4, 2026**, Typhoon Dolphin is heading westwards across the Pacific Ocean toward Japan, with strong winds and heavy rains already impacting the region; the storm previously caused damage in **Miyakojima** in Okinawa prefecture on **July 11, 2026**, from Typhoon Bavi, and Dolphin is forecast to hit the same area. The system is expected to remain well south of mainland Japan throughout the week before likely moving near the **Nansei Islands (Ryukyu Islands)** and eventually into the East China Sea, though the exact path beyond that point remains highly uncertain, with possibilities including Japan, the Korean Peninsula, or eastern China [Al Jazeera, Aug 4].

The key question of whether super typhoon Dolphin will hit Japan directly is now central to regional weather monitoring, with the current probability of a direct impact assessed at **80% YES** versus **20% NO** in the market tracking this event. Senior scientific officer **Kong Yu-chau** from the Hong Kong Observatory noted on **July 31** that the storm was expected to move toward waters south of Japan in the coming days, but its subsequent trajectory remained uncertain. Weather analysts, including **Xin Xin** of Weather China, stated that forecast models continue to diverge on the storm’s path beyond next week, with the potential for it to curve toward Japan’s main islands or veer into the East China Sea. The next critical window is the storm’s approach to the **Ogasawara Islands by Tuesday**, which will provide clearer data on whether Dolphin maintains a course toward Japan or shifts westward, ultimately determining the accuracy of the current high probability assessment [SCMP, Jul 31].
