In "Omihara and Omihara", the room that Omihara passes through before he meets with Fish Hagrid is called something in ancient Japanese architecture, and what does it do?

Oh, that's a question for me to answer.

This kind of room is called "Sanban-no-ma" (さんだんのま) in Japanese, and it is divided into three small rooms and three sliding doors.

The three small rooms are called "jikan no ma," "chikan no ma," and "げだんのま," and "げだんのま," respectively, in Japanese. げだんのま)

我简单画一张图，你凑合看吧。

Okay, let's move on to what these three houses do.

Rooms of this structure only existed in the homes of ancient Japanese nobles, and not just any nobles but top nobles, such as those of daimyo or the royal family.

Their role was mainly to hold meetings, meet guests and receive foreign guests. Status was highly valued in ancient Japan, so when you entered a room like this parlor, you would sit in different places depending on your status.

The lowest-ranking people sat in the "Shimodan-no-ma" room.

The highest-ranking person (or the head of the family) sits in the upper room.

The three sliding doors actually separated the three houses, so that when the person in the "lower room" had something to report, he had to report to the second house, the "middle room", and then the "middle room", the "middle room", the "middle room", the "middle room", the "middle room", the "middle room", and the "middle room". Only when the person in the "middle room" feels that it is necessary to continue to report the matter will he tell the person in the "upper room".

In addition, if the person sitting in the "upper room" is the Emperor of Japan, there will be an additional sliding door or curtain.

Normally, only one door is opened for reporting, but if there is an important matter, then the doors are opened one by one so that the person in the lower section can see the person in the upper section directly and report the contents to him.

To expand on this, I'm going to say a few more words:

The place where a group of people are kneeling in the picture is the "Lower Section"

Then the place where 5 people are kneeling with each other is the "Middle Section"

The top section of the picture is the "Middle Section"

The top section is where the people kneeling with each other are the "Middle Section"

The place where one person sits at the top is "Kami-ban-no-ma"

This is a picture of the Taisho (government) during the Tokugawa Shogunate era, and the person who sits at the top is the Shogun, Yoshinobu Tokugawa.

At this point perhaps you're wondering why the sliding door is missing. It's because the sliding door here was intentionally removed because this is where Ashikaga Yoshitaka, the shogun of the Muromachi shogunate, was poked and prodded to death by insurgents through the sliding door hundreds of years ago. ..... (Although Ashikaga Yoshihide was a shogun, he was also a skilled swordsman, nicknamed General Swordsman, and had a collection of swords. The rebels couldn't beat him, so they poked him to death with a sharpened bamboo through a sliding door)
