Kanji Literal Meaning
"Great Corner"
True Etymology
The characters mean 'great' (大) and 'corner/nook' (隅). The name likely refers to the southeastern corner of Kyushu, the Ōsumi Peninsula, which forms a prominent geographic angle. The 'great corner' describes the prominent cape geography of the region.
Alternative Theory
The Ōsumi Peninsula's Tanegashima Island, technically within Ōsumi Province, was the site where Portuguese traders introduced firearms to Japan in 1543—a moment that transformed Japanese warfare and ultimately contributed to Oda Nobunaga's military dominance.
