This is a talisman from Dazaifu Tenmangu Shrine, which enshrines Sugawara no Michizane, the god of learning. It is unused, but has aged somewhat due to storage, resulting in slight discoloration. However, it is believed that its efficacy remains. Approximately 24cm tall x 7cm wide. Thanks to the powerful academic protection of Dazaifu Tenmangu Shrine, one of the strongest in the country, I successfully passed a difficult national certification exam last year. I will pass this on to someone who needs it.
