The Look it up file is an Excel-file. You can search on specific words or parts of a word by using the search screen. You can also search by using Japanese characters. That makes it possible to find
the name of the maker of your Satsuma object, even when you are not familiar with Japanese language and have no clue what is on it.
As an example, see the picture of this mark, what consist of three characters:
Try to focus on the most simple part of the mark, in this case it is the last character: 川
Look in the database, starting with the first name and scroll down, untill
you recognize this character. You wil find it in the name Chikusen: 竹川. Compare the characters with the mark depicted here, and it's obvious that Chikusen is not he right name. But it is very useful to find it, because now you can
copy the 川 character, and put it in the search screen.
From now on the computer looks for you, and will continue the search for names with 川 in it. All you have to do is to compare what you see on the
screen with the mark what you want to identify. It will not take a long time before you find 長谷川 as being the name of Hasegawa. You will also find that this is the name of an individual maker and not a company name, and that
he was active during the Meiji period.
Now you have identified the name of the maker, you can check in the Marks & makers file if you can find more examples of this mark. Since there are
almost 2000 names in the Look it up file, and only 500 names in the Marks & makers file, this will not allways be the case. But in this case the name Hasegawa can also be found in the data file Marks & makers, with
several examples of his mark, and in the file Makers: examples you will find a depiction of his work. Since you know now a makers name, it is also possible to search on the internet and see if there
is more information about this maker.
