Hikarigaoka

 (光が丘公園) is a district in the, and the original home of the eight Chosen Children who fought in the Digital World in 1999.

This place is notable for being in the other end of a Digital Gate, which is highly vulnerable for breaching. In 1995, a Parrotmon emerged from the gate, and fought a battle with a Greymon that emerged as an egg from the computer of the Yagami family. Many children saw the battle with their own eyes, including the eight future Chosen Children, who were chosen that night to protect the Digital World in the future. The damage caused by the battle was attributed to a terrorist bombing, prompting the children's families to move away.

In Adventure, seven of the eight children returned to Hikarigaoka and remembered the event, and hypothesized that the remaining Chosen Child must have been from Hikarigaoka too. They searched for all the children who moved away from Hikarigaoka after the attack, but it later turned out that the eighth Chosen Child had been Yagami Hikari all along.

In Digimon Adventure 02, Oikawa Yukio brought the children he kidnapped to Hikarigaoka, where he was halted by Demon. The younger Chosen Children, who had been chasing Oikawa, stopped to fight Demon and save the district by exploiting the Digital Gate and forcing Demon into the World of Darkness. Oikawa managed to escape, not before instructing the kidnapped children to meet him in the district on December 31st. The older Chosen Children's Digimon spent several days to try and seal the Digital Gate to Hikarigaoka, but they were not quick enough. After Black War Greymon was critically wounded by Oikawa several days later, he decided, with his final breath, to seal the Digital Gate for good. However, Oikawa and the kidnapped children still met up in Hikarigaoka on December 31st, but instead of going through the sealed Digital Gate, they ended up in one of the worlds parallel to the Digital World, a world of dreams.
