Tropical Storm Chan-hom is currently tracking toward central Honshu and is forecast by the Japan Meteorological Agency to make landfall near the Tohoku or Kanto region on August 11, providing the dominant near-term driver for the 77.5% market-implied probability of at least one August landfall. The 2026 Pacific typhoon season has been unusually active, with 16 named storms by early August and above-normal formation expected through the month, increasing the chance of additional systems following recurving tracks into Japan. Official model guidance shows good agreement on Chan-hom’s path despite potential weakening from cooler sea-surface temperatures and dry-air entrainment before terrain interaction. Historical August climatology supports multiple approaches to Honshu, reinforcing trader consensus that the threshold will be met even if later storms deviate.

A tropical cyclone is a system classified by the Japan Meteorological Agency (JMA) as a tropical storm or stronger, meaning maximum sustained winds (10-minute average) of at least 34 knots (17.2 m/s), in the JMA advisory in effect immediately prior to the landfall. A system classified only as a tropical depression, or as extratropical, dissipated, or absorbed, at that time does not qualify.
Landfall means the center of the tropical cyclone's circulation physically crosses the coastline of Honshu. A system whose center crosses the coastline only of Hokkaido, Kyushu, Shikoku, Okinawa, the Ryukyu Islands, or any smaller island, or that passes over or near Honshu without its center crossing the Honshu coastline, does not qualify.
The primary resolution source for this market will be the Japan Meteorological Agency's position advisories (https://www.jma.go.jp/bosai/map.html#contents=typhoon&lang=en). If a JMA advisory plots the storm's center over Honshu, this market resolves "Yes" regardless of what other sources say. If no JMA advisory plots the center over Honshu but credible international news reporting confirms a crossing occurred between discrete advisory fixes, this market resolves "Yes", with classification taken from the most recently issued JMA advisory prior to the confirmed crossing time. Where a JMA advisory and credible reporting make contradictory claims about the storm's position at the same point in time, JMA is the default resolution source.
Once a qualifying landfall is reported, this market may remain open for up to 36 hours to establish confirmation, after which it will resolve according to the latest JMA data. This market may resolve based on the initial JMA advisory reporting a qualifying landfall regardless of any later advisory, retraction, best-track revision, or reanalysis that changes the storm's classification or position at the time of landfall.
