Uwajima: Ehime's Sea Bream Rice and Castle Town

Meet a southern Shikoku port town where an original hilltop keep, a heart-shaped garden and a famous raw sea bream rice bowl share one easy walk.

Quick answer: Uwajima is a castle town in southwestern Ehime Prefecture on Shikoku, home to one of only twelve original castle keeps in Japan and a regional dish called taimeshi. Uwajima-style taimeshi is fresh sea bream sashimi dipped in a sauce of raw egg, soy sauce and dashi, then spooned over hot rice. Allow a day to see the castle, garden and lunch.

People search for Uwajima when they want a quieter side of Shikoku, with real samurai-era history and seafood that tastes of the nearby Uwa Sea. The town is compact, the castle sits right in the middle of it, and the signature meal is easy to find at local restaurants. This guide covers the castle and its builders, the Date family connection, the garden, how the rice dish is made, other local flavors, and the train route most visitors use to reach the town.

Why Uwajima is worth a stop

Uwajima sits on the western side of Ehime Prefecture, facing the Uwa Sea, which is known for rich fishing and pearl farming. It is often described as a place where castle-town history and seafood culture meet. The Japan National Tourism Organization (JNTO) points out that Uwajima Castle is one of only twelve castles in Japan to retain its original keep, and that the clean sea nearby supports some of the country's main pearl producers.

For travelers, the appeal is scale. Everything central is walkable, crowds are light compared with big-name destinations, and you can combine history, a garden and a lunch of local specialties within a few hours. That makes Uwajima a good counterpoint to busier stops such as Matsuyama, with its famous hot spring, or the pilgrimage temples that draw so many visitors to Shikoku.

Uwajima Castle and its original keep

Uwajima Castle stands on a hill in the middle of the city, around a 20-minute walk from JR Uwajima Station. According to English Wikipedia, the military leader Todo Takatora built the castle between 1596 and 1601, working from an earlier fortification, and then spent about six years rebuilding it from 1601. The keep you see today is a later structure: Date Munetoshi replaced the former tower with the present three-story building in 1666.

The keep is small and graceful rather than imposing, which is part of its charm. Inside, exhibits show swords, armor and items related to the castle's history. Because it is an original structure rather than a modern reconstruction, wooden stairs are steep and interiors are simple, so wear shoes that are easy to remove and take your time. The walk up the hill is short and pleasant, and the keep looks out over the city.

The Date family connection

The name Date will be familiar to history fans because of Date Masamune, the famous lord of Sendai in the north. Uwajima has a link to that family. English Wikipedia explains that under the Tokugawa shogunate the Uwajima domain was granted to Date Hidemune, the eldest son of Masamune and the head of a branch of the Date clan.

JNTO notes that the Date clan lived at the castle for about 260 years, and another major travel guide describes the rule as lasting roughly two and a half centuries. Either way, the family shaped the town's culture for generations. The Date Museum, next to the castle, displays the family's possessions and tells the story of Uwajima and its lords, giving context to everything else you see in town.

Tensha-en, the heart-shaped garden

Tensha-en is a landscape garden next to the Date Museum. JNTO says the 7th Date lord built it in 1866, and its central pond is shaped like the kanji for "heart," pronounced kokoro. Walking the paths around the pond is a relaxing way to slow your pace after the castle climb.

The garden is especially lovely in April, when wisteria blooms. As with all seasonal flowers in Japan, timing changes with the weather each year, so look for recent bloom reports if flowers are your main goal. Even outside the peak, the garden's pond, stones and trees offer a calm scene, and it fits well into a short half-day walk with the museum.

Taimeshi: Uwajima's sea bream rice

Taimeshi is the dish most people mean when they search for Uwajima food. The version served in Uwajima is not the sea bream rice many Japanese cooks make at home. Instead, slices of fresh sea bream (tai) are dipped into a sauce of raw egg, soy sauce and dashi (a Japanese stock), then placed over hot rice, often with toppings such as seaweed, sesame, nori and spring onion.

JNTO describes the dish as one of Japan's top 100 local dishes, a list compiled by the Ministry of Agriculture, Forestry and Fisheries. Two accounts of its origin are told. One links it to sailors of the Iyo Navy who could not use open flames aboard ship; another links it to Uwa Sea pirates who ate sea bream sashimi over rice. Fishermen later prepared it on their boats. Earlier versions used any sashimi, including horse mackerel, and sea bream became the standard in the Showa era (1926 to 1989).

Ordering and enjoying the dish

Most restaurants in the city serve taimeshi, and JNTO says it is widely available throughout Uwajima. Pour the egg-and-dashi sauce over the sliced fish as directed, mix gently and eat while the rice is hot. Diners who prefer to avoid raw ingredients should ask the restaurant about options, since ingredients and preparation vary by shop.

A useful point of confusion: elsewhere in Ehime, "taimeshi" often means rice cooked together with sea bream. Ehime is Japan's leading producer of sea bream, both wild and farmed, and sea bream is the prefectural fish, so the fish appears in many forms. When you are in Uwajima, say you would like the raw-fish-over-rice style if you want the local specialty, or look for "Uwajima taimeshi" on the menu.

Other tastes of the area

Seafood is the thread running through local menus. Jakoten is a light fried fish cake made from the whole fish, with a rustic flavor and a pleasant chew, and it is a familiar snack and side dish in the region. Rural areas around the city are also associated with freshwater eel, wild pheasant, shiitake mushrooms and peaches, though availability depends on the season and the restaurant.

Pearls are another local identity. The seas around Uwajima are described by JNTO as clean enough to support major pearl production, and you may see pearl jewelry in shops. If you plan to buy, ask about the origin, grade and care instructions, and compare prices calmly, as with any specialty souvenir.

How to reach Uwajima and plan the day

Reaching Uwajima takes a little planning. JNTO suggests taking the Shinkansen from Tokyo or Osaka to Okayama, then the Shiokaze limited express to Matsuyama, and changing to the limited express Uwakai. The final leg from Matsuyama takes about 80 minutes, and the full trip from Okayama is around 4 hours.

Because it is a longer journey, many visitors stay one night. A simple plan is to arrive by midday, visit the castle and Date Museum, walk Tensha-en, enjoy a taimeshi dinner and head onward the next morning. Check train times in advance, as limited express frequency on Shikoku is lower than in big cities, and verify castle opening hours and admission on the official local tourism site before you travel.

Frequently Asked Questions

What is Uwajima taimeshi?

Uwajima taimeshi is a bowl of hot rice topped with thin slices of fresh sea bream that are dipped in a sauce of raw egg, soy sauce and dashi. It differs from the sea bream rice cooked in a pot that is common elsewhere in Ehime. It is widely served throughout the city.

Is Uwajima Castle an original castle?

Yes. JNTO notes that Uwajima Castle is one of only twelve castles in Japan to keep its original keep. English Wikipedia says the present three-story keep was built by Date Munetoshi in 1666, on a castle first built by Todo Takatora around the turn of the 17th century.

How long should visitors spend in Uwajima?

Half a day covers the castle, the Date Museum, the Tensha-en garden and a taimeshi lunch. Because the journey from Okayama takes around four hours, many travelers stay overnight, which makes the visit calmer and leaves time for a seafood dinner.
