In this blog, we touch on diverse topics about Japanese food cultures, practices together with the culinary secret, TREHA®, and its important role in the Japanese food industry. We hope our blog helps you obtain in-depth knowledge of the secrets and science behind Japanese cuisine, shared from our kitchen, to yours.

What is Izakaya and why is it so popular?

Have you ever heard of Izakaya(居酒屋)? It refers to a casual restaurant or bar where people gather to enjoy alcohol, food, and nibbles. We see Izakaya downtown, in business and entertainment districts, marked with red paper lanterns. For business people after work, or college students after class, people flow into Izakaya establishments to gather and unwind. I am almost certain that every Japanese adult has enjoyed Izakaya at some point in their life. Why Izakaya is so popular?

Large varieties of alcohol and food

Izakaya menu is centered around enjoying alcohol. Although Edamame (boiled green soybean), Sashimi (raw thin fish fillet) and Karaage (Japanese fried chicken) are popular classics, each restaurant and region has characteristic specialties. One of the features of Izakaya is a course of dishes that pairs with “all-you-can-drink”. Customers can enjoy a course of dishes including an appetizer, main dish, side, and dessert, and unlimited alcohol drinks from a specific menu range. To avoid excessive drinking and food loss, the restaurants have a “one glass at a time” policy; customers can order free refills of their drinks in exchange for their empty glass.

A comfortable and relaxed atmosphere

Izakaya is a place where you can come as you are – there is no dress code. The atmosphere is lively, and is one of the best places to spend time with your company.

Affordability

Many people are attracted to Izakaya because it is affordable. Nibbles are usually plated in small portions, to allow patrons to enjoy the variety the menu has to offer, without spending too much money.

Experience of food culture

The local atmosphere of Izakaya is well received by people who have traveled from abroad. They can enjoy Japanese food culture and the atmosphere of a local restaurant at reasonable prices. Can’t speak Japanese? No worries. Most chain Izakaya restaurants have introduced multi-lingual tablet devices for ordering.

Izakaya at an unexpected location – Izakaya abroad.

It has been a while since sushi and ramen became popular worldwide. The next potential trend is actually Izakaya! It is spreading throughout the downtowns of New York and San Francisco as a space to experience foreign culture, and also in Asia as a variation of Japanese restaurants.

I encountered Izakaya unexpectedly while talking with my team member in Thailand. He said that he visited a “new-style Izakaya”. After asking questions, I realized he was referring to a very classic style concept in Japan, “Zashiki ”(座敷); the room was covered with Japanese traditional tatami mats, and requires people to take off their shoes. He described his first experience in an Izakaya as very social and great fun. The people mixed around the room as the room didn’t have any chairs. I never expected to be talking about the classic Zashiki style restaurant with people from Thailand, and felt proud of how Japanese culture had brought such a fun experience abroad.

TREHA® - a secret ingredient behind Izakaya scenes.

Many Izakaya face challenges with food quality loss after serving. Customers are frequently absorbed in conversation, or away from their seats to socialize with others. Although people try to consume their meal while fresh, their aim is not always achieved as Izakaya is a casual place meant for socialization.

TREHA® tackles the challenges with maintaining freshness, without changing the taste of food. It can be used as a basic seasoning along with salt and pepper. With its high water retention ability and low sweetness, TREHA® contributes to:

  • Maintaining the juiciness of fried chicken after serving.

  • Keeping a leafy salad crisp and fresh.

  • Maintaining the soft texture and quality of cooked rice.

I would like to introduce one of my favorite dishes at Izakayas: "Dashimaki Tamago". This delightful Japanese rolled omelette is a staple in many Izakayas. By adding 3% TREHA® to the eggs, the texture remains soft and workable, making it easy to roll. This addition also ensures a moist and fine texture, resulting in a beautifully presented dish.
