Bamboo Spear

The Spread Shot of Hata no Kokoro from the world reborn (a Touhou LW original). She thrusts a bamboo spear at her foes. In Japanese, there are two distinct types of bamboo―take and sasa. They are very similar, and it's often difficult to tell them apart. Both plants have culm sheaths (leaves that wrap around the stem), but take's fall away as it grows, whereas sasa's remain attached. However, given that definition, yadake, or arrow bamboo, would be classed as sasa, and okamezasa, also known as ruscus-leaf bamboo, would be classed as take. Which is all to say, take and sasa really are very similar.
