The Question: What part of the mitsumata shrub is used for papermaking?
A The shiny green leaves
B The inner bark
C The yellow flowers
The tough, bendable inner bark of the mitsumata bush is steamed, boiled in alkali, bleached in cold running water, and beaten with wooden mallets. Phew. No wonder its common name in the West is ‘paperbush.’
The correct answer is The inner bark.
