Morning Glories in Japan: A Summer Bloom Full of Tradition

In the heat of Japan’s summer, delicate blue and purple flowers bloom quietly in windowsills, schoolyards, and shrine markets. These are asagao—morning glories, one of the most iconic and beloved plants of the Japanese summer.

But in Japan, morning glories are more than just pretty flowers—they are part of tradition, education, and everyday life.

A Childhood Memory: Growing Asagao in Elementary School

For many Japanese children, the morning glory is their first gardening experience. In elementary school, students are often given their own small pot and seedlings to care for. Every day, they water and observe their plant, learning about growth, responsibility, and the passage of time.

When summer vacation begins, children take their morning glory home to continue caring for it—and to watch it bloom in the early morning light. It’s a small but beautiful part of childhood in Japan, remembered fondly by generations.

Morning Glory Markets: A Festival of Flowers

Every July, some shrines and temples host special Asagao Markets (Asagao Ichi), where vendors sell potted morning glories in full bloom. The most famous is the Iriya Asagao Market in Tokyo, held at Iriya Kishimojin Temple. Visitors can browse dozens of flower varieties, enjoy traditional snacks, and soak in the nostalgic atmosphere.

These markets are not just about buying plants—they are about celebrating the fleeting beauty of summer and connecting with tradition.

Green Curtains: Cooling with Nature

Morning glories also serve a practical purpose. Many homes and schools use them as part of a “green curtain”—a natural screen of vines grown along windows and balconies. These green curtains help block sunlight, reduce heat, and save energy during Japan’s hot and humid summers.

It’s an eco-friendly solution that adds beauty and shade at the same time.

Whether it's a childhood memory, a peaceful garden moment, or a thoughtful way to cool your home, the morning glory holds a special place in Japan’s summer life. Simple yet meaningful, its soft blooms remind us to slow down, enjoy nature, and welcome the new day.
