The festival known for the releasing of thousands of lanterns into the night sky in Japan is the Tōrō Nagashi. This festival typically takes place during the summer, particularly around the time of the Bon Festival, honoring deceased ancestors. Participants float paper lanterns on rivers or release them into the sky, illuminating it with soft, warm glows. The lanterns symbolize the guiding of spirits back to the afterlife, creating a beautiful and spiritual atmosphere. Cultural practices associated with this festival reflect deep appreciation for familial ties and remembrance.
