Japanese seals are widely used, and all kinds of formalities need to be stamped.
The shape is generally round. Although the square seal is equally effective, the round seal is more mainstream.

attach another picture with a name stamp similar to the one below. Does it have legal effect on the contract? PS: This kind of name stamp can be made for 1 yuan on Taobao.
The contract law stipulates: "If the parties conclude a contract in the form of a contract, the contract is established when both parties sign or seal it." According to the provisions of this article, it is a valid contract if the signature is replaced by the name stamp in form. However, because this seal has not been filed by the competent authority (for example, the official seal needs to be engraved and filed at the Public Security Bureau), it is not unique, and the other party can deny that it is his own seal at any time (he can make a different one), which fails to achieve the purpose of the contract.
Therefore, in practice, the signatures and fingerprints of natural people are used as evidence, and the name stamp in your picture is generally invalid, although there is no problem in form; Unless the seal is notarized or authorized by a natural person with other documents, it is confirmed that it belongs to him.
