Shimoda

Shimoda (下田) is a place that is famously known for its resorts and Onsens. It is also where Nagi visits her mother's grave yearly on the anniversary of her death.

Sanzenin Mansion in Shimoda
Sanzenin Mansion in Shimoda (三千院家別宅に下田島) is the vacation home of the Sanzenin Famliy in Shimoda. The exterior of the main building is the same as Nerima's except the entire mansion is smaller.

Shimoda Onsens
There are many onsens in Shimoda. An important one is the one that was hit by a meteor. People say that due to the meteor's influence, the onsen has the power to make girl's breasts grow larger, make one smarter, regain lost supernatural powers or make a girl become more sexy. Although none of these are true, the onsen still had the power to split Nagi's other self from her.

Another one is the Saginomiya Onsen (鷺ノ宮温泉). This is the place that Ayumu and Hinagiku accidentally met. It is also the place that Nagi and Maya found the latter's space ship.

There is also an onsen owned by the Sanzenin Famliy called the Sanzenin Onsen (三千院温泉), that is located within the Shimoda town.

Yukariko's Grave
Yukariko's Grave (紫子の墓穴) is the place where Yukariko is buried after having passed away. Nagi, Isumi, Sakuya, and Wataru visit this place every year for the anniversary of Yukariko's death. Yukariko had picked this spot for her resting place because Shimoda was where she had spent her honeymoon with her husband, Shin Hayek.
