|Over a century ago, the shogun we Azumabitos descended from had a son. He was on friendly terms with King Fritz and often came to Paradis. After the Great Titan War, Hizuru was defeated and in disarray. In the confusion, a child of the shogunate was left behind on the island.|
|— Kiyomi Azumabito recounts Hizuru's recent history|
Hizuru (ヒィズル Hizuru?) is a small nation occupying a part of the Orient (東洋 Tōyō?, lit. "East Sea"). Despite being a smaller nation, Hizuru is known for producing talented engineers and developing relatively advanced weaponry and aircraft.
Hizuru previously allied itself with the Eldian Empire prior to their defeat during the Great Titan War. Following their defeat, the nation fell from glory, leaving it the only nation in the world willing to engage in diplomacy with Paradis, due to it wanting to monopolize the natural resources found on the island.
Over a hundred years ago, Hizuru was allies with the Eldian Empire. A son from the Shogun clan (that would later become the Azumabito family) had a close relationship with the Fritz family and often visited Paradis Island. When King Karl Fritz moved the capital of Eldia to Paradis and erected the three Walls, that son was stranded on the island. The son who stayed in the island later began the Asian clan inside the Walls. After Hizuru's defeat during the Great Titan War and the Eldian Empire's collapse, its reputation was tarnished and the nation was thrown into disarray.
Early in the Marley Mid-East War, Kiyomi Azumabito is invited by Zeke Jaeger to join forces with the residents of Paradis. After some back and forth discussions, Zeke is able to convince Kiyomi that the nation would greatly benefit due to the presence of Iceburst Stone on the island and they formally agree to join forces. Hizuru then begins to help Paradis prepare for an assault on Marley at some point in the future.
In 852, Kiyomi visits Paradis Island as an ambassador for Hizuru. She meets Mikasa Ackermann, the descendant from the Shogun clan that had once held power in Hizuru. In a meeting, Kiyomi explains a method in which Hizuru would aid Paradis island in modernizing its infrastructure, although she inadvertently makes it clear that Hizuru is allying primarily for financial incentive.
In 853, Hizuru refuses to help Paradis Island trade with other nations because they want to keep all of its resources for themselves.After the end of the war, Willy Tybur calls upon the leaders of other countries to join him for a festival in Liberio where he would announce his solution to the problem of Titans. Hizuru sends Kiyomi and several others to attend the event. At a gathering on the eve of the festival, she expresses sympathy towards the Subjects of Ymir, by covering up for a Warrior candidate spilling wine over her kimono. Kiyomi then departs, leaving the candidates in awe of her benevolence.
After the Raid on Liberio, Kiyomi visits Paradis with an observation unit to witness the Titans' rumbling and informs Dhalis Zachary the leaders of Hizuru have nothing but praise for the bravery shown by the nation of Eldia. Zachary thanks them while stating their victory would not be possible had it not been for the strong trust their nations have in one another.
- The name "Hizuru" (ヒィズル Hizuru?) is phonetically similar to "Hizuru-kuni" (日出ずる国 Hizuru-kuni?), a name for Japan which translates as "Land of the Rising Sun," referring to the nation's location in the far east of the early known world. In the context of Attack on Titan, this becomes ironic since the sun is said to rise in the west in this reality.
