Here's a quick rundown of the royal family's assets.
The Japanese Imperial Family is supported by taxes and has no income of their own. Therefore, the Imperial family does not have any huge accumulated assets.
All equipment used in the ceremony are national property of the Japanese state. Even the house they live in.
The former Emperor loved to drive a car. During the ceremony, the Emperor sits in the back seat of a car. The price of this car is 10 million yen. Of course it is the property of the state.

However, when the former emperor was driving a car, he bought it himself. The price of the car is 1.2 million yen. The Emperor does not have much money to spend personally. Because the money that the Emperor can use personally is also tax money.

So why doesn't the Japanese Imperial Family have any assets? The reason is that it has been over 800 years since the Japanese Imperial Family last ruled the country. Since the birth of the samurai government, the assets of the Imperial family have continued to decline. And during the Edo period, the Imperial family was finally controlled by samurai. The Imperial family's assets were abolished, and the operating costs were covered by the shogunate.
During the Meiji period, the imperial family's property was restored, but they did not have the right to use it freely. This is because the rulers had simply changed from samurai to politicians, and the Emperor no longer had any real power. Now, all of the Emperor's assets are managed by the government.
