National Treasure West Cocoon Warehouse Conservation Work Viewing Deck

West Cocoon Warehouse Conservation Work Viewing Deck
In West Cocoon Warehouse Conservation Work Viewing Deck, history and conservation plan of West Cocoon Warehouse as well as results of dismantling investigation works are explained through an exhibition displaying video and graphic panels. You can also see real time conservation work in progress through window glasses (partially from the inside too) and feel the atmosphere of a conservation work site. In addition, please enjoy a view of Tomioka Silk Mill from the 3F floor of the viewing deck.
This is a time-limited experience : you can enjoy the landscape changing with the seasons and the evolution of the conservation work until the bareroof is dismantled. We are looking forward for your visit.
Let's discover "Doibuki", the way artisans cover the roof with thin cedar boards
Specialized artisans perform "doibuki" (covering the roof with thin cedar boards before laying roof tiles) as part of the conservation and restoration of "West Cocoon Warehouse", a national treasure. Before march, you can see the artisans at work on a TV screen installed in the viewing deck. In early march, you may be able to see it directel from the plateform.

"Doibuki" (often called "tap-tap covering") means covering the roof Noji boards with thin wooden boards in order to prepare the surface on which the roof tiles will be laid. This process is different from "Kokerabuki", used for temples and shrines roofs, in which thin boards are the final roof covering material. However, artisans set every board with bamboo nails exactly the same way.

This is a unique opportunity to witness traditionnal craftsmanshift. Don't miss it!

<Period> Until about the end of March, 2018
※You may be able to see it from close from early march.
