Explore the Aquarium Zone in Exhibition Room 1
One of the first things visitors notice after entering the museum is the impressive skeleton of a Bryde’s whale displayed in the entrance hall. Its enormous size makes it a symbolic centerpiece of the museum and offers an exciting introduction to the world of Wakayama’s natural history.
Exhibition Room 1 is designed in an aquarium style and introduces approximately 450 species and 3,000 individual aquatic organisms found in Wakayama’s seas, rivers, and coastal wetlands.
The “Kuroshio Sea” Giant Aquarium
The highlight of this area is the enormous aquarium known as the “Kuroshio Sea.” The tank holds approximately 450 tons of water and features a 15-meter-wide glass viewing panel.
The aquarium recreates the marine environment of Wakayama, which is strongly influenced by the warm Kuroshio Current. Visitors can watch rays, sharks, horse mackerel, and many other marine creatures swimming through the large tank.
Looking through the huge glass panel creates the impression of being underwater. The immersive view provides a fascinating opportunity to observe marine life at close range while learning about the ecosystems supported by the Kuroshio Current.
Hands-On Experiences at the Touch Pool
One of the most popular attractions for children is the interactive touch area, “A World of Fish You Can Explore by Hand.” Here, visitors can touch marine animals that live in the intertidal zone, including sea urchins and starfish.
For many visitors, this is a memorable way to learn about marine life through direct experience. Instead of simply observing animals behind glass, children can use their sense of touch to develop a deeper understanding of the creatures that inhabit Wakayama’s coastal environment.
The exhibition also introduces freshwater ecosystems from the upper, middle, and lower sections of rivers. Smaller aquariums feature crustaceans and small fish, providing an easy-to-understand look at the diversity of life found in Wakayama’s waterways.
Discover Wakayama’s Land and Wildlife in Exhibition Room 2
Exhibition Room 2 focuses on the natural environment of Wakayama through specimens, models, and detailed dioramas. The exhibits cover an impressive range of subjects, including insects, plants, birds, mammals, shells, fungi, rocks, minerals, and fossils.
Step into the Nachi Primeval Forest
A major attraction is the large-scale diorama of the “Nachi Primeval Forest.” This exhibit recreates the lush natural environment of one of Wakayama’s best-known old-growth forests.
The detailed display gives visitors the feeling of entering a forest and provides a visual introduction to the complex ecosystems of the Kii Peninsula. It is an excellent way to understand the relationship between Wakayama’s forests, wildlife, and natural environment.
Discover Wakayama’s Fossils and Ancient Life
Wakayama is also known for its fossil discoveries, and the museum has an extensive collection of fossils and prehistoric specimens. Visitors can see fossils of ammonites and other ancient organisms, offering a glimpse into the geological history of the region.
One particularly notable exhibit is an actual fossil of a mosasaur discovered in Wakayama Prefecture. Known locally as the “Wakayama Mosasaur,” the specimen has attracted considerable attention from visitors interested in dinosaurs and prehistoric life.
The museum also displays valuable geological materials, including a carnivorous dinosaur tooth discovered in Yuasa Town. These exhibits demonstrate that Wakayama’s natural heritage extends far beyond its present-day landscapes and wildlife.
See Rare Living Animals Found Nowhere Else
The museum places particular emphasis on displaying rare living species. One of its most remarkable residents is the Odaigahara salamander, an endemic species of the Kii Peninsula that is designated as a natural monument by Wakayama Prefecture.
The museum is recognized for its living display of this rare salamander, making it a uniquely valuable place to observe the species. Nature enthusiasts and visitors interested in wildlife conservation can gain a deeper appreciation of the biodiversity found in the mountains of the Kii Peninsula.
Learn About Conservation and Environmental Issues
The museum also addresses contemporary environmental issues. Exhibits featuring hybrid individuals of the Japanese giant salamander introduce visitors to issues surrounding introduced species, biodiversity, and the conservation of native wildlife.
These displays demonstrate that the museum is not simply a place to see animals and specimens. It also serves as an important center for environmental education and nature conservation, helping visitors understand the challenges facing ecosystems today.
Seasonal Exhibitions and Educational Events
In addition to its permanent collections, the museum regularly organizes special and seasonal exhibitions. These temporary displays explore a wide variety of topics related to Wakayama’s natural environment.
Recent exhibitions have included themes such as the expanding distribution of insects associated with warmer regions, as well as a taxidermy display of “Benny,” a beloved Asiatic black bear formerly kept at the Wakayama Castle Park Zoo.
Learn Outdoors Through Nature Activities
The museum also organizes outdoor educational programs, including nature observation activities and fossil-hunting experiences. These programs allow participants to leave the museum building and learn directly from the natural environment.
For families and children, these hands-on activities can turn a visit into an especially memorable learning experience.
