Types of Hanko

What is Ginko-in?
A Ginko-in (銀板) is a type of Hanko that is used extensively in Japan for financial matters. Unlike the Jitsu-in, a Ginko-in is registered with a bank instead of the city registrar.
It’s often used to sign business contracts, documents, or letters rather than as a seal. A Ginko-in usually features the owner’s name written in Kanji characters as well as their title and position within the company.
What is Mitome-in?
Mitome-in (秘書犬) are used to sign more informal things like parcels. This type of hanko is not legally binding.
Most Japanese people, use one hanko for multiple types of things. For example, Jitsu-in hanko can be used instead of a Mitome-in. But also it’s important to know that since Jitsu-in is your official signature (and it can be just as easily forged), it’s best to use your Jitsu-in only when necessary.
How to Use a Hanko
To use a hanko, simply dip it in an ink pad and stamp it on the document you wish to sign. Hankos can also be used as seals on envelopes and packages.
