Field notes
Humid subtropical (Western Honshu) — similar pattern to Fukuoka but slightly cooler. Summer (June–August) is hot humid; the rainy season (June) is structural. Winter is mild and dry by Japanese standards. Spring and autumn are the cleanest working windows. Setouchi inland-sea geography moderates extremes.
