June, the rainy season, is hydrangea (ajisai) season in Japan, and Wakayama’s shrines, temples and hillside gardens fill with thousands of blooms in shifting blues, purples, pinks and whites. Hydrangeas are the flower of the rains — they look their best when wet, the colours deepening and the heavy heads bowing under raindrops — so this is one of the few times when a grey, drizzly day genuinely improves the view. Local hydrangea sanctuaries line stone paths and shrine approaches with banks of flowers, offering a quiet, atmospheric outing in a month most travellers write off.

Tips
Don’t be put off by rain — hydrangeas genuinely look best wet, so a drizzly June morning is the ideal time to visit rather than something to avoid. Bring an umbrella rather than a raincoat for photographs, wear shoes with grip as stone paths get slippery, and pair the outing with a hot-spring soak afterwards to make a perfect rainy-season day.
