You've probably heard the term "omakase sushi" but haven't given it much thought. "Omakase" literally means "leaving the specifics of an order to the store" in Japanese
In sushi, ordering a "omakase" is simple: ingredients are put on a plate randomly. However, "omakase" and "osusume," or what a shop would actually prescribe to a customer, can be very different in every time.
So, why is the omakase system so common in Japan, and how do restaurant staff decide what to serve? Let's take a closer look at what makes Japan's Omakase scheme so appealing.

When did the Omakase method become popular?

Omakase is not a centuries-old Japanese tradition, contrary to popular opinion. The word is said to have originated in sushi restaurants during the 1990s, when it became popular.
Before the 90s, Sushi restaurants had a relatively high entry barrier. They could be quite expensive, It was popular for gourmets who knew everything there was to know about fish to appreciate the fine artisanship of sushi. Out of reverence for the sushi chefs' abilities, they would always do so without consuming much alcohol.
There was Japan's bubble economy.With the sudden affluence came a slew of newcomers to sushi restaurants. These customers, with their pockets stuffed with cash, were unfamiliar with sushi's 'high culture,' but would still patronize high-end sushi restaurants. They yearned for what had previously been unavailable, and although they were unfamiliar with seafood, they realized they wanted a range of side dishes and liquor.
As a result, sushi culture developed to meet the changing demands for various types of goods. Customers were satisfied with the popular menu items, which included sake and side dishes. However, since many newcomers were unfamiliar with fish, there was a need for a system that allowed them to place an order and leave it to the chef, saving them the embarrassment of not knowing the name of a specific fish, especially when seasonal fish was used. "Omakase" was created to help them save face.

Chefs liked omakase because it allowed them to serve fish and other ingredients that they had on hand without disappointing their customers. And, rather than having to choose individual things, customers could simply leave it to their trusted restaurant hosts and continue their conversations with friends and colleagues.

Why do the Japanese want Omakase without knowing menu?

Actually there is 3 reason why Japanese people love omakase

1. It's  hard and annoying to decide what to eat.
Omakase is a system that is really for a people or a group of people that can not decide what to eat.

Even in a restaurant, there are a variety of other reasons why people may hesitate to make a decision. For example, they may want to maintain a humble attitude while out, and they may not want to be in charge of placing a group order. As a result, the omakase scheme is extremely practical: the decision is clearly delegated to the shop's workers.
2.Saving face!
Anyone ordering something that involves specialized knowledge, such as sushi in a high-end sushi restaurant or a fine wine in a French restaurant, would be anxious. Customers' expectations of each other can be at stake in sushi restaurants: how well do you know your fish? Are you aware of what's in season and what isn't? Or what is the best fish to order?

Likewise, in a French restaurant, You may be impressed with someone's expertise based on how they choose a bottle of wine. And your relationship with that person - coworker, lover, mate - will have an impact on the impression you want to make with your own experience.

Instead of making an mistake, you can easily defer to the staff's knowledge - "omakase" - and not bear the weight of the decision while still scoring points with your companions.
3. Trusted in professional!
Shop staff are trained professionals who understand how to read customers. They are also very knowledgeable about their goods. If you can request a "osusume" (recommendation), you can also leave the entire decision to them.

And, if you leave it up to the workers to decide what to eat for dinner, they will be able to recommend the best pairings for you. Most Japanese are aware of this and are willing to leave it to the experts.

They then ship approximately 5-10 pieces, and customers can purchase only the items they want. It's a new kind of Omakase service that caters to a wide range of customer needs, such as those who can't take time out of their busy schedules to get new clothes or who don't think they have a decent fashion sense.

Fukubukuro bags (lucky bag)
Fukubukuro bags, which are sold in department stores and consumer electronics stores in Japan shortly after the New Year, are a popular item. Fukubukuro will frequently have a label stating what type of contents are inside and how much it costs, but no information about the goods that are inside. As a consequence, it can be seen as a kind of omakase gift package.

Basically, the value of what's inside the fukubukuro is several times the amount actually paid. if you like a mastery bag or box thing this is it.

Is it possible to set conditions when you have omakase? can you cancel?

If you prefer Omakase, it is polite to leave everything to the specialist. Few people ask for a sommelier’s wine recommendations and then change their mind after their order has been put and the bottle has been opened. However, for food like Omakase sushi, you should verify and confirm the ingredients you don’t like ahead of time, and you can even share allergies with the workers. Please enjoy the Omakase adventure if you have communicated your expectations or conditions in advance!
