Regarding civil engineering works in areas containing buried cultural properties

Buried cultural properties are cultural properties such as the remains of houses and other artifacts such as pottery that are buried in the land. In addition, land where the existence of buried cultural properties is known (well-known buried cultural property sites) is mainly said to be ruins. Currently, 161 ruins have been confirmed in Inagi City.
If you plan to carry out civil engineering work on a site known to contain buried cultural properties, notification must be submitted at least 60 days before the start of construction. If you have any construction plans, please contact the Lifelong Learning Division.

If you have any questions about whether your area is a site containing buried cultural properties, please contact the Inagi City Local History Archives on the second floor of the Friend Hirao complex. Please bring a guide map or map showing the planned project site. If you are far away, you can also contact us using the dedicated form.
We do not accept inquiries by phone. In order to ensure the accuracy of the relevant areas of the storage land, we will respond to inquiries through the counter or a special form. Thank you for your cooperation.

Please fill in the necessary information in the dedicated form, attach the map, and submit it.

If the location where you are conducting civil engineering work falls under the category of buried cultural property, you will need to submit a notification based on Article 93 of the Cultural Properties Protection Act.

1. Guide map (a residential map with markings, etc.)
2. Construction and building floor plans
3. Construction/Building cross section
4. A letter of consent from the landowner (if the submitter is not the landowner)

• Please submit the application to the Cultural Properties Section of the Lifelong Learning Division on the 2nd floor of the Inagi City Local History Materials Room at least 60 days prior to the start of construction.
• The number of copies to be submitted is two (original: to be submitted to Tokyo, copy: to be submitted to Inagi City).
• All documents, including drawings, must be submitted on A4 size paper .
• The submitter must be either the land owner , the construction entity , or the person responsible for construction .

The submitted documents will be sent from the Inagi City Board of Education to the Tokyo Metropolitan Board of Education, and the submitted documents will be delivered to the submitter in about two weeks. Whether or not an excavation survey is required will be determined based on the following classification.
The submitter and the Inagi City Board of Education will discuss this, so please contact the Lifelong Learning Division if you receive a notification.

1. When buried cultural property is excavated due to construction work, etc.
2. When there is a risk of impacting buried cultural properties due to the construction of embankments or temporary structures, etc.
3. When constructing permanent buildings, roads, etc.

In this case, the investigation costs will be borne by the business operator.

1. When it is not possible to determine the presence or absence of buried cultural property by observing the ground surface, and it is necessary to confirm its presence or absence
2. When buried cultural property exists and excavation is required, it is necessary to understand the details of the property and its characteristics.

In this case, the city will conduct a partial excavation survey in advance.

1. When the excavation depth is planned to be less than the surface of the remains
2. When past survey results show that there are few remains in the area
3. For small-scale construction projects

In this case, city officials will be present during foundation work etc. to check whether there is any impact on buried cultural properties.
An inspection will be conducted, and if remains or other structures are confirmed, a preliminary investigation may be carried out.

1. In areas where preliminary surveys have already been conducted
2. In areas that have already been leveled

Even in such areas, we ask that you take care when carrying out your project so as not to affect buried cultural properties.
