Tea Porridge (Chagayu) | History and Recipe of “Okaissan,” Nara Prefecture’s Representative Local Cuisine
What is Tea Porridge?
Tea porridge (chagayu) is a traditional local dish representative of Nara Prefecture. It is a porridge made by cooking rice in brewed roasted tea or common tea, and unlike ordinary white porridge, it is characterized by a light, smooth mouthfeel. In Nara Prefecture, it is affectionately called “okaissan” and has been cherished as an everyday food since ancient times.
So deeply rooted is this dish in Nara’s food culture that there is a saying: “The morning of Yamato begins with tea porridge.” In contrast with Kyoto’s white porridge, it is also called “Kyoto’s white porridge, Yamato’s tea porridge.” It is a simple yet profound local cuisine born from the combination of “rice” and “tea,” two staples representative of Japanese food culture.
History and Origins of Tea Porridge
Legend of Emperor Shomu and the Construction of the Great Buddha of Todai-ji
There is an interesting historical legend behind the spread of tea porridge in Nara. The encyclopedia “Kojirui-en,” in its section “Food and Drink Part Six,” contains the following passage:
“In Yamato, even farming households eat tea porridge four or five times a day. During the reign of Emperor Shomu, when the Great Buddha of Todai-ji Temple in the Southern Capital was being constructed, people in households ate porridge and conserved rice to assist with the construction work, and from that time, porridge became the main food.”
According to this account, during the construction of the Great Buddha of Todai-ji Temple by Emperor Shomu in the Nara period, common people began eating tea porridge to conserve rice. The theory goes that tea porridge, which contains a lot of liquid, spread so that many people could eat with less rice while supporting a large-scale construction project.
Tradition in the Yoshino Region
Particularly in the Yoshino region of Nara Prefecture, tea porridge has long been cherished under the affectionate nickname “okaissan.” This name reflects both familiarity and respect for the porridge, suggesting it held cultural value beyond mere sustenance.
Tea porridge was eaten not only in Nara Prefecture but also in Wakayama Prefecture and the Iga region of Mie Prefecture; however, the nickname “okaissan” was a unique way of referring to it used in Nara Prefecture, particularly in the Yoshino region.
Establishment as Everyday Food
As evidenced by the record that tea porridge was eaten four or five times a day, it was not a special dish for the people of Nara but a staple food eaten daily. Tea porridge appeared on the dining table for breakfast, lunch, and snacks, playing a central role in Nara’s food life.
Major Regions of Tradition and Spread
Dissemination Throughout Nara Prefecture
Tea porridge has been eaten throughout Nara Prefecture as a local dish, developing as a unique food culture particularly in regions such as Yoshino and Katsuragi. The type of tea used, ingredients, and level of saltiness vary subtly depending on the region, reflecting the characteristics of each area.
Influence on Neighboring Regions
Centered in Nara Prefecture, the culture of tea porridge also spread to Wakayama Prefecture and the Iga region of Mie Prefecture. This reflects not only geographical proximity but also historical exchange and cultural connections.
Characteristics and Ingredients of Tea Porridge
The Secret of Its Smooth Texture
The greatest characteristic of tea porridge is its “smooth” and light mouthfeel. While ordinary white porridge becomes sticky from rice starch, tea porridge, through the action of tea tannins, allows rice grains to separate easily, resulting in a smooth finish with more moisture. This unique texture is why the dish has been cherished as easy to eat even in hot summers and gentle on the digestive system.
Main Ingredients Used
Basic ingredients:
- Rice (cold leftover rice is often used)
- Roasted tea or common tea
- Salt (a small amount)
Ingredient variations:
- Sweet potato
- Vegetables
- Legumes
The type of tea used—whether homemade common tea, roasted tea, or powdered tea—varies depending on the region and household. The level of saltiness also differs by region and household preference, creating varying flavors.
How to Make Tea Porridge (Basic Recipe)
Ingredients (Serves 10)
- Rice: 5 cups (or cold cooked rice approximately 1.5 kg)
- Roasted tea (tea leaves): about 50g
- Water: 3–4 liters
- Salt: a small amount
- Sweet potato: desired amount
Basic Preparation Method
1. Brew the tea
Fill a large pot with plenty of water and add roasted tea leaves to brew. Making a strong brew brings out the distinctive aromatic flavor of tea porridge. Using a tea infuser bag makes it convenient to remove the leaves later.
2. Remove the tea leaves
After brewing sufficiently, remove the tea leaves. A dark brown tea liquor will be ready.
3. Add the rice
If using cold rice, add it to the brewed tea. If making from raw rice, wash the rice and add it for cooking. Using cold rice is more traditional and saves cooking time.
4. Add ingredients (optional)
If adding sweet potato, cut it into appropriate sizes and simmer together. The subtle sweetness of sweet potato enriches the flavor of the tea porridge.
5. Cook
Bring to a boil over medium heat, then lower to low heat and continue cooking until smooth and light. Ideal is a state with more moisture than ordinary porridge, with rice grains separated.
6. Season
Adjust the taste with a small amount of salt. Tea porridge is traditionally made with restrained seasoning, and a level of saltiness that enhances the aromatic quality of roasted tea and the natural sweetness of rice is preferred.
Cooking Tips
- Using cold rice makes it easier to achieve a smooth texture
- Brew the tea strong so the flavor stands out
- Adjust the amount of water according to preference, aiming for a smooth finish
- Ingredients can be arranged seasonally with vegetables or potatoes as desired

Main Differences
Tea porridge:
- High moisture content and smooth texture

- Developed as an everyday food in Nara Prefecture
- Called “okaissan”
Nara tea rice:
