Japan is one of the world’s largest tea producers. While its famous matcha dominates the market, Japanese people enjoy many other types of tea, including kombu tea. This unique drink has been cherished for centuries and is unique in Japanese culture. Let’s explore this excellent tea together more!
What is kelp tea?
Kelp tea is a delicious and nourishing drink made from kombu, a type of edible seaweed. Unlike regular tea, kelp tea doesn’t come from tea leaves – it’s a seaweed-based infusion with a savory, slightly salty taste. There are various types of kelp tea. Some are made only with kelp, while others include extra flavors like matcha, beet sugar, or umeboshi (pickled plum) for a unique taste.

People have enjoyed kelp tea in Japan since the Edo period (1603-1868). However, some legends say it was used in the 10th century to help cure illnesses. Over time, it became a symbol of happiness and good fortune. Because the word kombu sounds similar to yorokobu (to be happy), it’s often served at weddings and New Year’s Day to bring luck and joy. In the Kansai region, a special version called daibukucha or oobukucha is served during the New Year to wish for health and prosperity.
Kelp tea tastes good and is also very healthy! It’s rich in iodine, which is essential for a healthy thyroid. It also contains minerals like calcium, iron, and magnesium. These nutrients help keep bones strong, support digestion, and boost the immune system. Plus, this drink also has antioxidants that help shield cells from harm. Since it’s low in calories and full of nutrients, many people drink this tea as a wholesome alternative to sugary drinks.
What is the difference between kelp tea and kombucha?
Kelp tea and kombucha may sound similar but are entirely different drinks! Generally, kelp tea comes from Japan and has been enjoyed for centuries. Japanese people make it by steeping chopped or powdered kelp in hot water, releasing its rich umami flavor.

Meanwhile, kombucha is a bubbly, fermented tea made from black or green tea mixed with a unique blend of bacteria and yeast called “SCOBY”. This drink likely originated in China or Russia and tastes tangy and slightly sweet. It is also known for its probiotic benefits that support digestion and immunity.
Unlike kombu tea, which is simple to make by just adding water, kombucha goes through a fermentation process and often comes in bottles with fruity flavors. So, if you’re looking for a warm and savory drink, go for kelp tea! If you want something fizzy and refreshing, try kombucha!

What are some ways I can enjoy kombu tea?
Chazuke
Chazuke is a simple yet tasty Japanese dish made by pouring hot tea or broth over a bowl of rice. It’s often enjoyed as a soothing dish after a long day, and you can even eat it as a quick breakfast! While green tea is the classic choice, kombu tea gives chazuke a rich flavor.

Seaweed tea powder dissolves in hot water to create an umami broth with a hint of ocean flavor. The warm and flavorful broth softens the rice, making it easy to eat! This version of chazuke pairs well with toppings like shredded nori (seaweed), sesame seeds, umeboshi, or grilled salmon.
Wafu pasta
Wafu pasta is a Japanese-style pasta dish that blends Italian noodles with delightful Japanese flavors. Instead of a heavy cream or tomato sauce, wafu pasta is seasoned with light and savory ingredients like soy sauce, mirin, and dashi. When made with kombu tea, it gets an extra boost of hearty flavor!

The powdered kelp tea dissolves into the sauce, creating a deep, rich flavor that pairs perfectly with mushrooms, bacon, or seafood. There are many types of wafu pasta, from creamy mentaiko (spicy cod roe) to soy-butter kinoko (mushroom), each offering a lovely twist on classic Japanese flavors.
Asazuke
Asazuke is a quick and easy type of Japanese pickle that lets you savor fresh, lightly seasoned vegetables in just a few hours! Common ingredients include cucumbers, cabbage, and daikon radish, gently pickled with salt, soy sauce, or vinegar.

The taste of asazuke is mild and refreshing, perfect as a crunchy side dish with rice or a light snack. To enhance this cherished side dish, sprinkle it with kombu tea powder for a naturally rich and delicious vegetable flavor.
Why is kelp tea so popular?
Whether as a comforting warm drink or a refreshing cold brew, kelp tea remains a special part of Japanese culture. From its deep history to its health-boosting properties, kombu tea is more than just a comforting Japanese drink; it’s a tradition that connects people to the ocean’s natural goodness!

It also works as a versatile seasoning that enriches the flavor of many dishes. Furthermore, it embraces a sense of tradition, bringing happiness and good fortune to Japanese culture.
