Shiroyama Park (城山公園, Shiroyama Kōen) is a park in downtown Kagoshima that extends over Mount Shiroyama. With an elevation of 107 meters, the mountain formerly served as the site of a castle fortification, which led to its name. Shiroyama literally means "castle mountain" in Japanese. The castle's former grounds at the base of the mountain now serve as the site of the Reimeikan Museum.
The park is most famous for its Shiroyama Observatory with spectacular views over downtown Kagoshima, Kagoshima Bay and Sakurajima. The night view is also nice, particularly if a clear sky and bright moon allow Sakurajima to remain visible. Nice views can also be enjoyed from the Satsuma no Yu outdoor hot spring bath at the nearby Castle Park Hotel, which is also open to non-staying guests. https://www.japan-guide.com/e/e4607.html
The Chiba Zoological Park, first opened in April 1985, is located about halfway between Tokyo and Narita, just outside of the city of Chiba.
The zoo is divided into seven sections: the Zoological Hall, the Small Animal Zone, the Steppe Zone, the Monkey Zone, the Avian and Aquatic Zone, the Ancestors of Domestic Animals Zone, and the Children’s Zoo. The Small Animal Zone houses Futa, the red panda who in 2005 became a television celebrity because of his ability to stand on his hind legs. His son, Kuta, now has the same ability, so you have twice the chance to see the spectacle when you stop by! The park map has pictures of the animals (at their locations), so there is no need to worry if you cannot get ahold of an English map.
If you can, it is extra special to visit the zoo between mid-March and mid-April, when the many cherry blossom trees onsite are in full bloom! https://en.japantravel.com/places/chiba/chiba-zoological-park/16
