YAEYAMA / WIND & TYPHOONS
In an average year, 7.7 typhoons approach the Okinawa region (1991–2020 normals). Wind is a rightful resident of the island year — and when travel plans change, wind is usually the reason. Knowing the structure of typhoons and sailing suspensions in advance lets you meet a windy day without panic. Drawn from public sources and this page's own eye.
TYPHOON SEASON
Every figure here rests on JMA sources. A typhoon is not a disaster that may or may not come — it passes over this sea every year, as part of the normal year. First, know that normal.
By climatological normals (1991–2020), 7.7 typhoons a year approach the Okinawa region. According to the Okinawa Meteorological Observatory, the season runs roughly from July to October, with approaches possible in May or November.
JMA typhoon normals ↗By month, August is the most frequent, with a normal of 2.2 approaches to Okinawa Prefecture. Island by island, the normal is 4.4 approaches to Ishigaki Island and 4.1 to Iriomote — figures from the Ishigaki Local Meteorological Office's annual report.
Okinawa Meteorological Observatory ↗By the JMA's definition, a typhoon “approaches” when its center comes within 300 km of a point. And typhoons do not arrive unannounced: the JMA issues track information continuously, days ahead. Before you travel, start with the official typhoon information.
Japan Meteorological Agency ↗WHY BOATS STOP
A cancelled sailing is not an operator's whim but a decision read from wind and waves. This page describes only the structure — which routes are said to stop, and when. Today's operating status is not here; it always lives on the operators' official pages.
A small, fast hull is more sensitive to waves than a large ferry — this is not a claim about any particular route, but this page's editorial generalization. On the same sea, the waves a boat can take depend on its size and speed.
Ishigaki Island's most frequent wind direction over the year is north-northeast, with an annual mean wind speed of 5.4 m/s; from October through April, north-northeasterly winds are the most frequent (JMA normals). Anei Kanko officially describes the Uehara route to Iriomote as a route that crosses open ocean, and when it is suspended, a connecting shuttle bus via Ohara Port is offered. By Yaeyama Kanko Ferry's official guidance, when the Uehara route is suspended you ride about 50 minutes by boat to Ohara Port and about 60 minutes by connecting bus to Uehara Port, on a Uehara-bound ticket that includes the bus.
Uehara route suspension guide ↗As a typhoon approaches, operators may announce an outlook that all routes and all sailings will be suspended; in one official example, the next day's operation outlook was announced the day before. The final word always sits on the operators' same-day status pages. This page holds the structure only — for current sailings, always go official.
Anei Kanko operating status ↗BUILT FOR THE WIND
Wind is written into the very shape of island life. In 1987, Taketomi Island's village was selected as an Important Preservation District for Groups of Traditional Buildings (category: island farming village; 38.3 ha). The townscape described below rests on the public sources listed at the end of the page.
Walls of piled Ryukyu limestone, and windbreak rows of fukugi trees around each house lot — both are the village's manners for letting the wind pass. Their lines along the white-sand lanes form Taketomi's landscape.
Know Taketomi Island →The houses are wooden and single-storied, with hipped roofs of lime-plastered Ryukyu red tile or thatch, their eaves kept low against typhoons. Not resisting the wind but living with it — that shape is recorded in the Agency for Cultural Affairs' description of the preservation district.
Taketomi Town Tourism Association ↗The Taketomi Town Tourism Association's visitor guidance calls Yaeyama a pathway of typhoons: for two or three days around an approach, the coasts see swell-driven high waves and strong winds, and boats and planes are affected. That, too, is part of island time. For the islands' rainy face, see the rain page.
To the rainy-day page →HOW TO READ A WINDY DAY
From here on, these are this page's editorial impressions. No forecasts and no promises about sailings — only a stance for windy days.
When an approaching typhoon appears in the track information, the choice usually comes down to two: cross early and stay longer, or let this one go. Both are right answers. The earlier you decide, the more boats and rooms are still yours to choose. The material for the decision always starts with the JMA's typhoon information.
Japan Meteorological Agency ↗On the night before boats look likely to stop, lay in a little extra water and food. If you end up riding out a typhoon on an island, follow your lodging's guidance and the islanders' instructions, for shutters and for how to spend the hours — the tourism association's visitor guidance says the same.
Island visitor guidance ↗On the day after the wind passes, the sea keeps its swell for a while and regains its color little by little. Only those who stayed on the island get to watch that change. And if you would rather choose a direction again, the compass awaits.

The typhoon and wind figures (approach normals, the monthly peak, the definition of “approach”, wind direction and speed) summarize the JMA sources below; the statements on the substitute route via Ohara Port and the shuttle bus when the Uehara route is suspended summarize the operators' official guidance; and the statements on Taketomi's townscape summarize the Agency for Cultural Affairs and the Taketomi Town Tourism Association — confirmed by 2026-11-01 (in part at the level of search-result titles and summaries). The generalization that high-speed boats are sensitive to waves and the passages on how to hold a windy day are this page's editorial impressions, not quotations. No forecasts, no typhoon tracks and no same-day operating status are included — always confirm officially at the time of travel.
