Yes. There are standard contract forms for private works prepared by a Japanese joint association of contractors etc. (‘Contractors Association’). Although the use of such forms is not mandatory, in most cases, these forms are, sometimes with several amendments, used by the parties when entering into a construction or engineering contract. For public works, there are also commonly used standard contract forms which are prepared by the MLIT. It is not common to use any international contract form for constructions in Japan.

The main parties involved in a construction contract are a building owner and a construction company. Designers and other professionals are sometimes retained directly by an owner and sometimes by a main construction company. In most large-scale constructions, sub-contractors and/or a construction joint venture is used. In the case of sub-contract, master-contractor is usually responsible for all of sub-contractors' work.

Risks borne by a contractor in a construction contract are usually in relation to failure to build, defective work or delay.
In general, a contractor that is unable to perform its obligations because of a force majeure event is not liable for consequences of such event so long as the contractor exercises due care of a good manager.

In private works, except for large-scale infrastructure constructions, construction bonds are not very common. In public works, the government authority often requires a contractor to secure a construction bond for default of payment by the contractor. It is not common that a surety would assume specific obligations of the contractor other than payment of moneys.

Parties can freely decide on methods and terms of payments in a construction or design contract. In small and short-term projects, payments are commonly made at the completion of the construction work. In large and long-term projects, payments are commonly made at the completion of agreed stages of construction. In public works, certain percentage of the contract price is often paid to a contractor before starting the construction.

The general limitation period for a party to bring a claim in the courts for breach of a contract is five years from when the claiming party recognizes the breach or ten years from the breach, whichever is earlier.
The limitation period for defect liability under the Civil Code is five years from when the claiming party recognizes the defect (breach) or ten years from the defect (breach), whichever is earlier. (In the standard construction contract form, except for certain types of defects in residential buildings for which the defect liability period is ten years from the delivery under the Housing Quality Assurance Act, (i) the defect liability period is two years from the delivery or (ii) as to interiors, furniture, or the like, the claiming party needs to do inspection after the delivery and to make a claim immediately after that, or if a defect cannot be found in such inspection, the defect liability period is one year from the delivery; provided, however, that if the defect has been caused by the contractor’s wilful misconduct or gross negligence, not these provisions but the Civil Code provisions apply.)
In addition, the claiming party is required to notify the contractor of the defect within one year from when the claiming party recognizes the defect; provided, however, that such notice is not required if the contractor knows the defect or does not know the defect with gross negligence. (In the standard construction contract form, this one-year notice requirement is excluded.)

The contractor is liable to the owner (end-user) which is a party to the construction contract for any physical damage or economic loss suffered by the owner in accordance with the general defect liability rules. In addition, the owner may request the contractor to repair defect(s) of the building. Even though there is no contractual relationship between the contractor and the owner, tort liability of the contractor could be sought by the owner in some cases. Or, in some cases, subrogation by the owner could be an option.
In the case where the owner is an individual executing a contract not for business, the contractor’s liability for damages cannot be excluded totally by any agreement between the parties. In the case of structural defect(s) of a new residential building, defect liability of the contractor (and the seller) cannot be excluded by any agreement between the parties. Under the Product Liability Act, the manufacturer of a product is liable for damages caused by a defect even if there is no negligence on the part of the manufacturer. This act does not apply to real properties, but applies to building equipment etc.

For sub-contractors, there is usually no contractual relationship with the owner (end-user). For an architect, designer or consultant, it depends on each case. Even though there is no contractual relationship between the contractor and the owner, tort liability of the contractor could be sought by the owner in some cases. Or, in some cases, subrogation by the owner could be an option.

Due to lack of contractual relationship with the contractor, third parties may not seek the contractor's contractual liability. Tort liability of the contractor could be sought by a third party in some cases. Or, in some cases, subrogation by a third party could be an option.

The Construction Works Dispute Settlement Board (CWDSB) was established under the BSA, which provides for settlement of construction disputes through mediation (assen), conciliation (chotei) or arbitration (chusai). In domestic deals, the CWDSB is often used, and in CWDSB about 30% is settled through arbitration. There is an arbitration agreement form to submit disputes to the CWDSB prepared by the Contractors Association.
Arbitration is more flexible in procedures than litigation through the courts and less time is required to obtain a resolution. In addition, arbitrators are usually experts in construction matters.
The CWDSB's arbitration is not very expensive because reward of arbitrators is not paid by the parties in the dispute.

As mentioned above, in addition to arbitration, mediation and conciliation are also available in CWDSB. Though the CWDSB was established under the BSA, use of ADR or the CWDSB is not mandatory.

In this country, what are the main rules relating to health and safety on construction sites? Do these rules in any way relate to the use of the development after construction is completed?
Under the Industrial Safety and Health Act (ISHA), employers are obligated to take measures necessary to prevent health hazards etc. at construction sites. The ISHA also applies to the use of the completed building.
Some examples of such health hazards are as follows:
Other than the ISHA, employers also have to comply with multiple guidelines published by the government.
