- Audience llm-inferred
- data scientists · climate and weather researchers · meteorological analysts · consultancy analysts on Japan-based projects
Limitations
- Constraints llm-inferred
- Japan only; no UK coverage, so it is not a fit for UK flood, drainage or civils work · Forecasts only; no observed rainfall, river level or flow data · All columns stored as strings, so values need casting before analysis · Source page is overwritten on each update; history depends on the daily collection · Date and time fields are in JST (UTC+9) · No train-test split; all data is in the train section · Publisher makes no guarantee of completeness or accuracy; JMA must be credited and the source's rules followed · Weather text fields are in Japanese · Single-maintainer scraper pipeline, so continuity is not guaranteed
