japan-seasons

Use 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.

Use 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.

Use 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.

Use 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.

Use 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.

Use this for January-February cherry blossom requests or when the user specifically asks about Kawazu-zakura, early blossoms, or the Izu Peninsula.

Use 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.

Use 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.

Use 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.

Use 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.
