Handmade using traditional Japanese papermaking fibres and available in a range of weights, it's favoured by conservators for repairs and mounting owing to its tear strength, chemical stability and visually unobtrusive qualities.

A closer look...
Shown here is a scrapbook containing photographs, newspaper cuttings, programmes, and other ephemera pertaining to the Maidstone Ladiesβ Speakersβ Club, 1983β1990 [ref. Ch146/M2/1]
β
After being accessioned and catalogued, it was necessary to remount much of the scrapbook's contents owing to the compiler's use of Blu Tack. Whilst marketed as a temporary adhesive putty, Blu Tack can fuse quite aggressively to documents and leave an oily residue if left in situ for too long. It therefore required careful removal using a spatula, scalpel, and tweezers.
β
Ensuring the original arrangement of the scrapbook was maintained, we chose polyester corners to resecure the photographs but opted for a type of Japanese tissue called Tengu to remount the paper ephemera. Made from kozo (bark fibre from paper mulberry), Tengu is an incredibly thin tissue weighing only 5 gsm and can be purchased as a 15 mm wide tape, conveniently pre-coated in a water activated starch adhesive. Rather than cutting it with scissors or a scalpel, we intentionally tear Japanese tissue as this produces a feathered edge that integrates more naturally with the documentβs fibres, resulting in a discreet repair. Pre-coated Tengu was the best choice for this project owing to the large quantity of ephemera that required remounting but in other cases, a conservator might opt to work entirely from scratch, using plain Japanese tissue and a hand-prepared starch paste.
β
The many other uses of Japanese tissue in paper, parchment, and book conservation include mending tears, reinforcing weaknesses (fragile edges, folds, etc.), infilling losses, backing fragile documents, hinging loose material, and mounting for display.
