During the rainy season in Akita Prefecture, the humidity clings to your body, and you can feel a cool, comfortable sensation. Oga Peninsula, Akita Prefecture. Surrounded by the Sea of Japan on three sides, this lush peninsula is blessed with nature, including a caldera. It has nurtured a unique culture, including Namahage and hearty hunter cuisine, creating a unique atmosphere.
Hydrangeas welcome visitors to Oga's 400-year-old Zen temple.

We headed to Unshoji, a Soto Zen temple celebrating its 400th anniversary. The deputy chief priest, Konaka Shuun, fell in love with a single hydrangea blooming in the temple grounds about 20 years ago and began dividing it into smaller branches. There are now over 2,000 hydrangeas. When in full bloom, the entire area is dyed blue.

Someone once described the scenery as "paradise on blue earth." Once you pass through the four-legged gate, a fantastical view unfolds before you. A blue carpet spreads out, tracing the undulating terrain of the grounds, which slope gently toward the main hall in the Zen Buddhist style.

While walking, I got lost on a bamboo forest path. The cool sea breeze tickled my cheeks.

Colorful hydrangeas are floating in the water basin. There are some really cool touches here and there.

The original souvenirs are also attractive, including original hydrangea-themed goshuincho (stamp book) (4,500 yen, tax included) and goshuin (stamps) (500 yen), amulets with different designs (1,200 yen), and amulets with preserved hydrangea flowers sandwiched between them (1,200 yen).
I was enchanted by the beauty of the flowers that bloomed bravely after surviving the intense heat.

Here and there, the cute Jizo statues, made in a workshop in Miyagi Prefecture, welcome visitors with their gentle expressions. Furunaka takes care of the hydrangeas himself. On the day we visited early in the morning, he was carefully pruning the plants with scissors in hand.

"Last year (2023), Akita had the highest average temperature in the country in August, and due to the heat, the flowers are blooming poorly now. Maybe only about 60% of the usual amount."

The hydrangeas at Unshoji Temple are all, so to speak, siblings, having survived the once-in-a-century heatwave together. The beauty of the flowers blooming bravely is awe-inspiring. A scene that brings courage to visitors spreads across the port town of Oga under the rainy season skies.
