Seizan Omamori

The story of the lute Seizan is told in Heike Monogatari chapter 7, part 18. The instrument was brought to Ninna-ji Temple for safe-keeping by Taira no Tsunemasa who never returned for it, having died in battle. You can buy the omamori. Source.

Jōmyō and Ichirai

Among the monks, there was a certain Ichirai, a man of great strength and agility, who served the holy teacher Keishū at the Jōenbō. Having followed Jōmyō and fought in his wake, this Ichirai now wished to pass him, but found the beam too narrow. "Your pardon, Jōmyō," he said. He put his hand on the flap of Jōmyō's helmet, made a brisk leap over his shoulder, and went on fighting.

Antoku

Emperor Antoku (1178-85) was enthroned at age two in place of his father the teenaged Emperor Takakura, who was forced into retirement by Tairo no Kiyomori as part of a wide-ranging Heike power grab. Antoku was Kiyomori's own grandson. Heike Monogatari spends the first three chapters building the case for the defeat of the Taira, but once that's in play sets out to create sympathy for them in their destruction, and pulls at the heartstrings with young Antoku's drowning during the final battle in the Shimonoseki Straits.  Source.

Shunkan

Several islands claim to be the place of exile of the monk Shunkan, who plotted against the Heike in 1177. His co-conspirators received pardons, but he conspicuously did not. There are Noh plays about it. This statue is in Iōjima in Kagoshima Prefecture. Source. Also.
