I'll introduce a expert of Otaru today, his name is "Mr.Takeuchi".
He guides about Otaru for tourists as a volunteer.
He visited us a few day ago.
Please look at the photo↗
Do you know what he is holding?
This is float glass.
(※Float glass is used for floatage of net of herring fising. Otaru prospered in herring fising. More than 100 years ago, there are not so many kinds of materials so, they used glass and the number of glass shops increased.)
In addition, he can tie float glass up with rope.
This technique is quite rare. He showed how to tie it up, he was like a workman :)
