Celadon Water Jug with Peony Design

Celadon Ewer with Peony Design — A Ming-Dynasty Masterpiece at Tokyo National Museum

Hidden among the vast Asian art collection of the Tokyo National Museum is a quietly magnificent ceramic vessel that captures more than six centuries of cultural exchange between China and Japan. The Celadon Ewer with Peony Design (Seiji Botan-mon Suichū) is a beautifully preserved water pitcher produced in the early 15th century at the legendary Longquan kilns of Zhejiang Province, China. With its deep, jewel-like green glaze and finely carved peony blossoms, it stands as one of the most representative examples of the celadon style that the Japanese came to call "Tenryū-ji celadon" — a name woven directly into the story of medieval Sino-Japanese trade. For travelers fascinated by the meeting points of Asian civilizations, this single vessel offers a rich window onto a moment when ceramics, religion, diplomacy, and aesthetics all flowed together across the East China Sea.

What Is This Ewer? A Vessel from China, Treasured in Japan

The ewer is a tall, lidded pitcher made for pouring water or wine, standing 34.5 centimeters in total height. Its body is gently pear-shaped, swelling toward the lower portion, with a long curved spout on one side and a gracefully bent handle on the other. The lid is crowned with a small finial shaped like a hōju, the wish-fulfilling jewel familiar from Buddhist iconography. The entire surface is bathed in a thick, glossy celadon glaze of deep, almost emerald green — the kind of glaze that seems to hold light within it, much as a polished piece of jade might.

What makes the vessel especially captivating, however, is the patient choreography of carved decoration just beneath that glaze. On either side of the body, the potter shaped panels in the form of ruyi-heads — a curling, cloud-like outline with deep symbolic meaning across East Asia — and inside each panel carved a single, full-bloomed peony. Surrounding these panels, fine arabesque scrolls fill the space with rhythmic curls. The neck of the ewer is wrapped in a band of upright banana-leaf motifs, while a circle of lotus petals rises from the foot. Each pattern was incised into the unfired clay before glazing, so that the glaze pools into the carved lines and reveals the design as a soft play of darker and lighter greens.

The Story of Longquan and Tenryū-ji Celadon

To understand why this vessel matters, it helps to step back into the world of medieval Asian trade. The Longquan kilns, located in the mountains of southern Zhejiang Province, produced celadon ware almost continuously from the Northern Song dynasty into the Ming. Japanese connoisseurs eventually divided this long history into three broad styles: the pale, delicate Kinuta celadon of the Southern Song; the deeper, more robust Tenryū-ji celadon of the late Yuan and early Ming; and the later Shichikan celadon of the late Ming. Our ewer belongs squarely to the second group, the Tenryū-ji style.

The name "Tenryū-ji" itself comes from the great Zen temple in the Arashiyama district of Kyoto. In the 14th century, the Muromachi shogunate dispatched official trade ships, known as Tenryū-ji bune, to Yuan China specifically to raise funds for the temple's construction. These vessels brought back enormous quantities of Chinese goods — and among them, large quantities of richly glazed Longquan celadon. Over time, the name of the temple became attached to that whole class of celadon, regardless of which ship had actually carried it across the sea.

Tenryū-ji celadon is typically larger and more imposing than the earlier Kinuta type, and its glaze tends toward a slightly warmer, denser green. Carved decoration — peonies, lotuses, scrolls, and symbolic panels — became more prominent during this period, reflecting both the technical mastery of the Longquan potters and the tastes of the international markets they served, which by then stretched from Japan all the way to the Middle East.

Why It Was Designated as a Cultural Property

The Celadon Ewer with Peony Design was officially designated an Important Art Object on December 20, 1934, and is also listed as a Registered Art Object under the Tokyo National Museum's care. Several factors lifted this particular ewer above its many siblings.

First, it is a textbook example of Tenryū-ji celadon at its peak. The proportions, the silhouette, the depth of the green glaze, and the carved decorative scheme together represent everything that defines the style. For scholars, it serves as a kind of reference point against which other works can be compared.

Second, the piece survives in remarkably original condition. Lidded ewers like this one are notoriously fragile — slender spouts and looping handles are exactly the parts that tend to break first — yet this example retains both its original lid (with its hōju finial intact) and the full integrity of its body. Few comparable Tenryū-ji celadon ewers have come down to the present day in such complete form.

Third, the ewer carries a long history of being treasured in Japan. It was brought to the archipelago in the medieval period and passed down with care for generations, evidence of how deeply Chinese celadon was woven into Japanese aesthetic life from the Muromachi period onward, especially in the world of the tea ceremony, where vessels of this caliber were prized as karamono — "things from Tang" — of the highest rank.

Highlights to Look For When You Visit

Standing in front of the ewer in the gallery, take a moment to slow down. There are several details that reward unhurried attention.

The first is the glaze itself. Move slightly to one side and watch how the green deepens and lightens as the angle changes. A good Longquan glaze was famously compared to jade, and you can see why — the surface has a softness almost like skin, but with a cool, mineral depth.

The second is the carving inside the ruyi-head panels. The peony was the "king of flowers" in Chinese tradition, a symbol of wealth, honor, and feminine beauty. The Longquan carver has rendered each blossom with broad, confident strokes, capturing the tension between full-bloomed petals and the curling leaves around them.

The third is the finial of the lid. This little jewel-shape, the hōju, is a Buddhist symbol meaning that all wishes are fulfilled. Its presence on what is essentially a serving vessel hints at the way Buddhism, Daoism, and everyday luxury were intermingled in Yuan and early Ming material culture.

Finally, look at the band of upright leaves around the neck and the lotus petals at the foot. These framing motifs were standard on prestige Longquan vessels, and they tie the ewer visually to a much wider family of celadon meiping (plum vases), incense burners, and bowls produced for export and for elite Chinese tables.

Beyond the Ewer — The Tokyo National Museum Experience

The ewer is part of the museum's Asian Gallery, the Tōyōkan, which sits to the right of the main Honkan building. The Tōyōkan opened in 1968, was redesigned by the architect Taniguchi Yoshirō, and underwent a major renovation completed in 2013. Spread across six effective floors via a clever spiral arrangement, it houses Chinese, Korean, Indian, Southeast Asian, Central Asian, and Egyptian art under one roof — one of the finest collections of pan-Asian art in the world.

The Chinese ceramics galleries on the upper floors are a particular delight for anyone interested in celadon. You can trace the development of glazed ware from ancient grey pottery through Yue, Ru, and Jun wares, into the full splendor of Longquan, and onward into the blue-and-white porcelain of Jingdezhen. Seeing our ewer in this wider context makes its place in the celadon tradition all the clearer.

Note that exhibits in the Tōyōkan rotate, and individual works such as this ewer are not always on display. If you are coming specifically to see it, it is wise to check the museum's online collection database or contact the museum in advance to confirm whether it will be on view during your visit.

Things to See and Do Nearby

The Tokyo National Museum sits at the northern end of Ueno Park, one of Tokyo's most rewarding cultural districts. After your visit, consider lingering in the area to deepen the experience.

Within Ueno Park itself, the National Museum of Western Art (designed by Le Corbusier and a UNESCO World Heritage Site), the National Museum of Nature and Science, the Tokyo Metropolitan Art Museum, and the Shitamachi Museum are all within a short walk. The historic Kan'ei-ji Temple and the famous Tōshōgū Shrine are tucked among the trees, offering a glimpse of Edo-period spirituality. In spring, Ueno Park is one of Tokyo's most beloved cherry-blossom viewing spots.

Just south of the park, the bustling Ameya-Yokochō (Ameyoko) market street offers a lively contrast — a tightly packed open-air market with food stalls, fishmongers, and casual eateries. For a quieter moment, the Yanaka district to the west has narrow lanes lined with old wooden houses, small temples, traditional sweet shops, and one of Tokyo's atmospheric historic cemeteries.
