I almost didn’t go. Winter peonies? It sounded like a contradiction. But my ikebana teacher mentioned them, and then my dear friend Chloe was so determined to visit that we pulled each other there. And I’m so grateful we did. My Middle Little (10) came along, and to my delight, loved them just as much as I did.

Make sure to check the Ueno Toshogu Shrine webpage for updated information on the blooms.

About Ueno Toshogu Peony Garden

The Ueno Toshogu Peony Garden, located within Ueno Park, is a hidden gem that offers seasonal displays of these breathtaking flowers. (It’s only open 3 times a year for these flower exhibitions.) The garden features over 500 peony plants representing a variety of species, carefully cultivated to bloom at different times of the year.

During winter, the garden showcases Kanto’s largest class of 160 winter peonies across 40 varieties. The winter peonies here are protected by straw roofs (warabuki) to prevent them from freezing. In addition to the peonies, you can also enjoy the sight of wintersweet, Japanese witch-hazel, and Japanese apricot in bloom, creating a serene and elegant winter landscape.

We even caught the beginning of the plum blossoms.
The Magic of Winter Peonies

Peonies are already stunning flowers, known for their delicate, ruffled petals and deep symbolism of prosperity and beauty. But seeing them bloom in the middle of winter feels like stepping into a fairytale. How does this happen? Careful cultivation and an ancient horticultural technique bring these flowers to life during the coldest months.

How They Grow in Winter
Unlike their spring counterparts, winter peonies (kan-botan) are coaxed into bloom through meticulous temperature control and protection. Skilled gardeners use a method called “forcing,” where the plants are encouraged to bloom at an unnatural time by adjusting soil conditions and carefully regulating their exposure to warmth and cold.
Why the Peonies Are Under Tents

One of the most striking elements of the Ueno Toshogu Peony Garden in winter is the sight of each peony nestled beneath a straw tent (warabuki). These traditional shelters serve multiple purposes:
- Protection from Frost & Snow: The straw coverings insulate the plants, shielding them from frost and ensuring their delicate petals don’t freeze.
- Shielding from Harsh Sunlight: Even in winter, direct sunlight can be too intense for fragile peony blooms. The tents help diffuse the light, keeping the flowers at their best.
- Aesthetic Beauty & Tradition: These conical straw shelters add a poetic element to the garden, blending the natural beauty of the flowers with traditional Japanese gardening techniques. Walking through them feels like traveling through another time.
A Must-Visit Winter Experience
Visiting the Ueno Toshogu Peony Garden in winter is a special experience that blends the magic of seasonal gardening with the tranquility of a Japanese garden. The crisp air, the mostly elderly crowd admiring the blooms, and the surreal sight of peonies defying the season make it unforgettable.

As we walked through the garden, my Middle Little pointed out the way the petals danced in the wind. We both loved photographing the blooms. The pictures here are a mix of his and my photography!

If you’re in Tokyo during the winter months, make time for the Ueno Toshogu Peony Garden. It’s a reminder that beauty thrives even in the coldest seasons, and sometimes, a gentle nudge from a friend is all you need to experience something extraordinary.
