Facilities like the exhibition center become loss making operations usually. 
It is thought that the exhibition center only has to be effective in activation of the region or the economic spread to industry. 

For instance, let's assume that the attendance of Tokyo Big Sight is 70,000,000 people in a year.
If these people used the fare of 1000 yen, transportation will obtain 70,000,000,000 yen in a year. If the profit is 10 percent, it is a profit of 700,000,000 yen in total.
When you include it to consideration, it is possible to allow the deficit within 700,000,000 yen. 

However, the independent profit system was introduced into Tokyo Big Sight. We were  ordered to earn all of the hall running expenses included personnel expenses (Tough the large mending is excluded) . In fact, it has been achieved. 
Besides, only Tokyo International Forum is managed with the independent profit system . 

The management of the center is operated directly to the local public entity or is consigned to the company usually. 
As for the management income at the center, all become the incomes of the country or the prefecture, and all the running expenses of the hall becomes expense of the country and the prefecture oppositely. The management organization adds the operating income to the needed cost and demands its amount to the country or the prefecture. 
Therefore, the management of the organization is steadier to adopt the consignment method than the self-sustenance method.

The reason why the self-sustenance method was introduced into Tokyo Big Sight is that there was an intention by which the management sense of the organization is promoted. 
If the capacity usage ratio goes up, work becomes tight. If it falls, easy to work . Both are regular the income, the management sense dulls, no matter how you encourage them. 

However, it is necessary to calculate of suitable of revenue and expenditure also in the self-sustenance to achieve this. 
Introductory remarks became long. Then, the charge setting becomes a big subject.

Naturally, the operation cost(-■- in left graph) increases at a fixed rate when facilities operate. 
On the other hand, the income(-▲- in left graph) increases in proportion to the capacity usage ratio. 
Therefore, earnings will exceed cost somewhere. （Management is a deficit in permanence in case of not being so. ）。

It becomes the break-even point capacity usage ratio as the income exceeds the maintenance expenditure. 

How many percent is this assumed?

However, there is being sure not to understand easily in the break-even point in as many as 600m in width hugeness facilities .
Anyway, the needed expenditure must be picked up as much as possible without the leakage. A big oversight becomes a mortal wound.

And, the capacity usage ratio that revenue and expenditure becomes the plus or minus zero is calculated. The charge for the facilities use is counted backward from this capacity usage ratio oppositely. 

As a result, the rough draft of bill of charges is completed. 
And, the charge setting examines whether it is possible to compete evenly to surrounding similar facilities again. 

And, the rough draft of the charge is reconsidered. The maintenance expenditure of facilities is reexamined, and ･･･････. 
A final charge is decided by that process.

Finally, being necessary to note is setting of the exception charge.
Revenue and expenditure was strictly calculated. However, it becomes not significant to have made a lot of exceptional discount setting. 

Especially, you must not install the reduction measures for the public office just like as this: "Reduction when judged that content of holding contributes to public interest". 
The public office insists as follows: "Why isn't there discount measures to use the building built with the tax of the resident for the public interest?". 

However, if this exception regulations are made, the facilities management is sure to become deficit. Then you would be criticized "This is a non-efficient facilities" . And the private side promoters who are using it by a regular charge moves to another facilities getting angry. 

It is despotic of the public office to demand the charge reduction while requesting the self-sustenance.

Well, I have lengthily spoken the ideal exhibition center up to now. In conclusion, the ideal exhibition center is facilities where earnings are obtained.

However, earnings do not go up only by setting a high charge from other facilities. 
The exhibition hall becomes "Ideal exhibition hall" which oneself and others both admit when better serves, better convenience and more a lot of customers  are secured  than the charge setting. 

Perhaps, I will not see Tokyo Big Sight of The Second while surviving. 

I want the exhibition center which Tokyo Big Sight is far surpassed to be built if there is a person who tries to build a new exhibition center somewhere all over the world. It is a reason to write this text.

Do you understand why?

The reason is that the appearance of the exhibition center better than Tokyo Big Sight becomes a mainspring by which Tokyo Big Sight would be led to a more ideal exhibition center. 

As the birth of Makuhari Messe made HARUMI fair ground transfigured to Tokyo Big Sight.
