What is the difference between lot number and residential address

The rainy season has started in western Japan and it has been raining since yesterday. The temperature is high and the humidity is very high, which makes us feel tired. Please take care of yourself.
Today, we received the consultation of real estate sale from the representative of the company which we had dealt with before. We will proceed with investigation from now on, and begin sale soon. Since there was a case peculiar to Kyoto in the case of a preliminary investigation, we will explain it to you.

In Japan, there are two types of addresses: lot numbers and residential addresses. What are the differences between the two?
#●●● △△△, Otsu City,  Shiga Prefecture
​
First, the lot number is a number given to each stroke of the land. (It is considered as one piece of land in the land register, and is a unit for counting the land.) In the notation by lot number, the lot number area is determined by the area corresponding to the city, ward, town, village, or character. Details of this lot number can be confirmed by examining the cadastral map at the Legal Affairs Bureau.

On the other hand, in residential addresses, the building is described by the town name, block code, and house number. For the house number of each building, the basic number where the doorway of the building touches is used.​ However, as Japan's urbanization progressed, it became more and more difficult to identify the location of the land with a land code, so in 1962, the Act on Indication of Residential Address was enacted and housing indication was implemented.
In accordance with the housing indication, the address "#△●●●, □□□, Otsu City,  Shiga Prefecture" is now written as "#●●● △-chome, □□□-cho, Otsu City,  Shiga Prefecture". Addresses in areas that do not have a residence indication are still using the traditional street numbers. That's right,  indication of residential address is not implemented in Kyoto City.
A lot number is mainly used for obtaining registration information and taxes, and a residential address is used to indicate the address to which mail is to be delivered. Even today, the importance of the land number for identifying land remains the same, so it is written in the registry as "#number, XX town, XX city".
​
Also, there is a map similar to the cadastral map called a property tax (land) lot number reference map. This is a map similar to the cadastral map, and lot number on the cadastral map mapped according to the current shape of the land. The reference map below is the same area as the cadastral map above.

As you can see, there are multiple addresses in real estate, and there is a lot number reference map used for property tax purposes from residential maps, even if it is a same location. If you are interested, please look up your own residence.
