What is Tea Okayu?

Tea Okayu (or Tea porridge), also known as ‘okaisan’ in some places, uses rice and tea as its main ingredients in Japanese cuisine. It’s considered a specialty in Yamaguchi, Wakayama and Nara Prefectures. It’s a simple yet special dish. Its comforting taste is like a soulful food enjoyed by people of all ages in Japan.

Tea porridge was actually the earliest form of ‘fast food’ created to reuse leftover rice during tough times. Though it might seem basic, it’s a clever way to make ordinary ingredients taste great without any waste.

This dish is also great for managing health. It’s a warm, healing meal for the weak or sick. Even though it’s simple, it’s full of nutrients and offers a balanced diet.

Tea Okayu


Origin of Okayu

Porridge is a dish widely enjoyed across Asia, including China, Korea, Thailand, Indonesia, as well as in Central and South America and Africa. However, its exact origins remain uncertain.

Historical evidence traces the existence of porridge in China back to at least 3000 years ago. In Japan, rice cultivation began during the Yayoi period. During this time, rice was typically ‘steamed,’ and the version cooked with water was referred to as ‘porridge.’ There were two types: a soft, moist porridge known as ‘soup porridge’ and a firmer version termed ‘solid porridge.’ The ‘soup porridge’ closely resembles today’s ‘okayu,’ while the ‘solid porridge’ resembled what is now considered regular cooked rice.

History of Tea Okayu

Chagayu, a dish known outside Yamaguchi Prefecture, is believed to have its roots in Nara. Around the early 17th century, Lord Yoshikawa from Iwakuni Domain in Yamaguchi promoted its use to save rice, spreading its popularity to places like Yanai City and Suo Oshima Town. By combining tea and boiling, it’s now considered a ‘healthy food.’

In Yamaguchi, Chagayu stands out for its method of using roasted bancha in a tea bag. It’s boiled in a special iron kettle called ‘kama,’ then rice is added after removing the tea bag. The dish boasts a smooth texture and is enjoyed warm in winter and cold in summer. Initially a staple for commoners, each family has its unique way of cooking it, turning it into a sort of ‘signature dish.’ Sweet potatoes, abundantly grown in Suo Oshima and Yanai, lend a gentle sweetness to ‘Imogayu.


It’s tasty when warm in winter or chilled by soaking in water during summer. It’s easy to eat, especially when you’re not very hungry because it feels smooth in your mouth. In the mountains, folks use bancha since they make their own tea, while in the plains, hojicha is common. I’ve never heard of using green tea.

Tea shops and supermarkets sell roasted tea and bancha in tea bags specifically for tea porridge. People from outside the area often buy these in bulk to make tea porridge. But even the regular roasted tea in tea bags can make it delicious.

Differences between porridge and tea porridge

When you think of ‘porridge,’ it’s usually a soft meal made by boiling rice in lots of water. It’s moister than regular rice, giving it a smooth, soft texture. You can add seafood, meat, or veggies to make it tastier and more nutritious. It’s easy to digest, so it’s used when you’re not feeling well or as a hospital meal.

But ‘tea porridge’ is made using tea instead of water. It’s part of the traditional Japanese diet for staying healthy. The tea’s aroma and taste soak into the rice, making it really flavorful. If you want, you can skip adding salt and just enjoy the tea’s flavor.

Both ‘porridge’ and ‘tea porridge’ are widely used in Japanese food culture. They’re versatile, used from everyday meals to managing health. With different flavors and nutrients, you can choose and enjoy them based on how you feel that day.
