Archaic or literary term for a protective barrier or defensive wall, often used metaphorically for something that guards or shields. Rare in modern Japanese.
The castle's bulwark prevented the enemy's invasion.
This law functions as a bulwark of freedom.
Rare kanji spelling; the variant 藩屛 is also recorded but even less common.
Archaic variant of 藩屏; the character 屛 is an older form of 屏.
From Chinese 藩屏 (fānpíng), meaning 'fence' or 'screen'. The characters 藩 (hedge, fence) and 屏 (screen, shield) combine to convey a protective barrier. The exact historical derivation in Japanese is uncertain; it is a literary borrowing.
