Yomiyama City

Yomiyama City is the main location of the series. Almost the whole plot of the series takes place in Yomiyama. Most of the locations are within this city (excluding Sakitani Kinenkan and The Beach) and all the characters (excluding Kouichi Sakakibara, who was only born here) are from this city. This location was first seen in episode 1, after Kouichi came to Yomiyama to live with his grandparents and his aunt.

Trivia

 * When Kouichi arrives in the city in the beginning of the anime, he says he's never been there before. But he was in Yomiyama to attend Reiko's funeral a year and a half ago. However, he can't remember this since the calamity altered his memory.
 * Actually, Kouichi's father remembers Reiko's funeral(or at least both of them visited Yomiyama City) as he mentions early in the series that it was one and one half years since the last time.
 * In the manga and novel, Kouichi didn't meet Izumi when he visited Yomiyama a year and a half ago.
