Available tools 8

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

ferry

ferry_cancellation_history

Day-by-day record of cancellations per route since 7 November 2026, from readings of the operators' status pages several times a day (worst reading of the day per operator), with a per-route summary: days recorded, days with any cancellation, days fully cancelled. Example: "How often has the Hateruma ferry been cancelled lately?"

ferry_status

Whether the ferries from Ishigaki to Taketomi, Kohama, Kuroshima, Iriomote (Ohara, Uehara), Hatoma and Hateruma are running today, per operator (Anei Kanko, YKF), read from the operators' own status pages. Values: ok, partial (some sailings cancelled), cancelled, or null when the operator has not posted yet (they post in the morning, Japan time). Example: "Are the ferries to Taketomi running today?"

best

best_time

Ishigaki and Yaeyama month by month: JMA temperature, rain and sunshine normals, typhoon approaches, 2025 visitor numbers, and what applies that month (rainy season, typhoons, habu jellyfish, north winds that cancel ferries, Japanese holiday peaks, festivals). Give a month, an interest, or neither for the whole year. Example: "Is October a good time to see manta rays on Ishigaki?"

island

island_guide

A recommended day on one island from Ishigaki, step by step (when, what, source), plus getting around, food, children, rainy days, staying overnight, local rules, crossing time, boats a day and the cheapest adult fare. Example: "What should I do on a day trip to Kuroshima?"

next_ferries

The next scheduled boats on one route from the operators' published timetables, in Japan time, with fares. direction 'out' is Ishigaki to the island, 'back' is the island to Ishigaki. Example: "When is the last boat back from Iriomote (Ohara) to Ishigaki?"

plan

plan_island_day

Earliest published boats for up to three islands in one day from Ishigaki: out, back, time on each island, when you are back in Ishigaki, or why it cannot be done. Uses the longest printed crossing, 30 minutes between boats, no backup sailings. Boats between islands are not used (you return to Ishigaki in between). Example: "Can I do Taketomi and Kohama in one day from Ishigaki?"

routes

list_routes

The seven ferry routes from Ishigaki Port with operators, crossing time, boats a day, first and last boat, and the page that explains each. Example: "Which islands can I reach by ferry from Ishigaki?"

which

which_island

Ranks the six islands reachable by ferry from Ishigaki (Taketomi, Iriomote, Kohama, Kuroshima, Hatoma, Hateruma) for the traveller's time, interests, month, children and sea conditions, with the reasons, the catches, crossing time, boats a day and the cheapest adult fare. Example: "I have one day on Ishigaki with two small kids and want a beach. Which island should we visit?"
