japan_seasonal_answerUse this first when the user asks a broad Japan seasonal travel question, including cherry blossom forecasts, autumn leaves, flowers, festivals, fruit picking, or what is good during travel dates. This is the best entry point for natural traveler prompts because it routes to the right live dataset and returns a ready-to-use recommendation. Do not use this for hotels, flights, trains, visas, restaurants, or generic itinerary planning unrelated to seasonal timing.
sakura_nowUse this first for broad cherry blossom prompts such as 'How is the sakura forecast?', 'Is sakura blooming now?', 'Where should I view sakura today?', 'Where should I see cherry blossoms this week?', or 'How is Kyoto sakura looking?'. Returns a concise current answer from live Japan Meteorological Corporation forecast and observation data, including specific viewing spot suggestions when current spot data is available, plus next-step guidance for the full park list and weather. Do not use this for autumn leaves, non-sakura flowers, hotels, trains, or generic itinerary planning.
koyo_nowUse this first for broad autumn leaves prompts such as 'How are autumn leaves looking?', 'Where is koyo good now?', 'Kyoto autumn leaves forecast', or 'Where should I see fall foliage in Japan?'. Returns a concise current answer from live Japan Meteorological Corporation maple and ginkgo forecast data. Do not use this for cherry blossoms, fruit picking, hotels, trains, or generic itinerary planning.
searchUse this for ChatGPT/deep-research style retrieval over Japan in Seasons. Searches live seasonal-travel dataset guides and returns result IDs for fetch. Use for questions about Japan cherry blossom forecasts, autumn leaves, seasonal flowers, festivals, fruit picking, weather, or the MCP server itself. Do not use for hotels, flights, trains, visas, or restaurants.
fetchUse this after search to retrieve a full Japan in Seasons result with citation URL and text. For live sakura or autumn leaves result IDs, this fetches the current forecast answer from live JMC data.
sakura_forecastUse this when the user asks about cherry blossom timing, peak bloom, whether sakura has started, or how cities compare across Japan. Returns Japan Meteorological Corporation forecast bloom dates, full-bloom dates, observed dates when available, historical averages, and status for 48 observation cities. Do not use this for specific parks or temples; call sakura_spots next for prefecture-level viewing spots.
sakura_spotsUse this when the user already knows the prefecture and needs exact cherry blossom viewing spots with current status and GPS coordinates. Each spot uses JMC reporter observations as the primary status when filed within the last 48 hours (states: pre-bloom through hazakura/green leaves); falls back to the JMC bloom-meter estimate otherwise, with any stale observation shown as secondary context. Also returns the prefecture's JMA reference station summary. Do not use this for nationwide timing comparisons or date matching; use sakura_forecast or sakura_best_dates first.
sakura_best_datesUse this when the user provides travel dates and wants to know where sakura is likely to be best during that trip. Returns cities whose viewing window overlaps the requested date range, based on observed or forecast full-bloom dates. Do not use this for January-February early-bloom Kawazu requests; use kawazu_forecast for those.
kawazu_forecastUse this for January-February cherry blossom requests or when the user specifically asks about Kawazu-zakura, early blossoms, or the Izu Peninsula. Returns the Japan Meteorological Corporation forecast comment, forecast map links, and Kawazu cherry spots with bloom percentages, full-bloom percentages, forecast dates, and coordinates. Do not use this for standard Somei-Yoshino sakura elsewhere in Japan.
koyo_forecastUse this when the user asks when autumn leaves peak, whether one city colors earlier than another, or wants a national overview for October-December. Returns city-level maple and ginkgo forecast dates, forecast maps, and regional commentary from Japan Meteorological Corporation. Do not use this for specific temples, gardens, or GPS-tagged locations; call koyo_spots next for those.
koyo_spotsUse this when the user already knows the prefecture and needs exact autumn leaves viewing spots. Returns Japan Meteorological Corporation koyo spots for one prefecture with best start, peak, and end dates, leaf type, popularity rating, and GPS coordinates. Omit prefecture to get a top-destinations guide. Do not use this for cross-city date matching; use koyo_forecast or koyo_best_dates first.
koyo_best_datesUse this when the user gives autumn travel dates and wants the best cities during that window. Returns cities whose maple or ginkgo viewing windows overlap the trip, based on forecast peak dates. Do not use this for general climate questions or for exact park recommendations without dates; use koyo_spots when the prefecture is already known.
weather_forecastUse this when short-range weather could change the recommendation, especially for sakura petal fall, rain risk, or packing advice. Returns the next 3 days of Japan Meteorological Agency forecast text, temperatures, and 6-hour rain probabilities for one supported city. Do not use this for seasonal bloom timing months in advance; use the sakura or koyo forecast tools for that.
flowers_spotsUse this for non-sakura flower trips such as plum, wisteria, hydrangea, lavender, sunflower, or cosmos. Returns curated flower spots with peak windows, official URLs, notes, and GPS coordinates. Do not use this for cherry blossom or autumn leaves timing; use the sakura or koyo tools for those live forecasts.
fruit_seasonsUse this when the user asks what fruit is in season in a given month or which month is best for strawberries, grapes, peaches, apples, and similar picking trips. Returns the fruit season calendar, peak months, best regions, and notes for 14 fruits. Call fruit_farms next if the user needs actual farm listings, map coordinates, or booking links.
festivals_listUse this when the user wants recurring Japan events to plan around, such as fireworks, matsuri, or winter festivals. Returns curated events with typical dates, attendance, official URLs, notes, and GPS coordinates. Do not use this for bloom timing, one-off concerts, or weather forecasts.
fruit_farmsUse this when the user needs actual fruit-picking farms, booking links, and map coordinates. Returns farms from the local dataset, and month filtering automatically narrows results to fruits that are in season. If the user only asks which fruit is in season, call fruit_seasons first.
