冒頭
ぼうとう · boutou · JLPT N1 · noun
beginning
冒 — top 冃 (cloth/cover) + 目 (eye)
Originally a pictograph showing a cloth or cap covering the eyes, suggesting something pulled down over the head. From this came the meaning 'to cover,' then by extension 'to risk' or 'brave through' (as in pushing forward despite obstacles). The top component 冃 is often miswritten as 日, but it depicts a covering, not the sun.
