Types and use of seals for business in Japan
A bank seal (銀行印) and a card seal (認印) are physically different and must not be mixed up; sole proprietors, unlike companies, don't need to register a seal (実印); a company seal is separately required…
It is important not to confuse a bank seal (銀行印) with a personal-use seal for a credit card (認印) — these are physically different seals that the bank and the card issuer each verify separately; using the wrong one can lead to a card block. Unlike a company, a sole proprietor (個人事業) is not required to register a seal (実印) — an ordinary personal seal (認印) is enough. A stamp bearing the company's address in Japanese is a handy accessory for documents and envelopes, sold on Amazon with customizable text (representative's name, phone number, company name); some users reported uneven printing on certain grades of printer paper — it's worth choosing paper suited to inkan stamping separately. A company seal is also required separately for certain banking procedures, such as getting a cash card at SMBC Trunk.
