Note: All photos, video evidence, and spectral analysis of the Fountain of White L are available exclusively to CovertJapan Patreon members at the "Urban Legend" tier.

After reviewing the evidence—the pulsating water, the suppressed academic papers, the priest’s testimony, and the 1945 aerial "L" formation—this journalist leans toward the former. Asuka is Japan’s Giza Plateau. And the Fountain of White L is its hidden Sphinx.

According to the priest, the fountain pulses. Unlike a geyser, which shoots water into the air, the Fountain of White L recedes and rises in a 70-minute cycle. This is impossible for a gravitational spring. Our team placed a GoPro inside the grotto for 12 hours. The footage (exclusive to our Patreon) shows the water level dropping precisely 47 centimeters every 70 minutes before surging back up.
