Tanabe is the second largest city in Wakayama prefecture, with an estimated population of 80,000. In contrast with the mountainous landscape of its neighbouring Shingu, Tanabe is a coastal city. Its major attraction, Tanabe Ogigahama Beach, is a perfect place to pass away a hot summer day.
The beach can be easily reached from the city center and it is a short walk from the Kii Tanabe Station.
If you are not a fan of sunbathing, I suggest you take a book and read it in the promenade facing the Pacific Ocean which is also located in the shore. I can't think of a better way to spend a summer evening.
