Surrounded by the sea and mountains, Wakayama Prefecture boasts a rich unique history and abundant natural blessings. This vast area is dotted with diverse attractions, ranging from historic castles brimming with atmosphere to dynamic natural landscapes, and even theme parks that let you forget the everyday.
However, many travelers likely wonder, ‘Where should I start?’ or ‘What are the real ways to enjoy places not found in guidebooks?’ This time, we’ve carefully selected 5 ‘truly worthwhile main spots’ that you absolutely must visit when in Wakayama. We’ll enthusiastically explain each facility’s often-overlooked deep charms and smart tips for navigating them!
Wakayama Castle
📍 Address: 3-3 Ichibancho, Wakayama, 640-8146, Japan
Wakayama Castle, soaring in the heart of Wakayama City, is the former residence of one of the Tokugawa clan’s three main branches, also known as ‘Torafusujō’ (Tiger-Lying Castle). While it’s a famous castle boasting one of Japan’s ‘Three Great Connected Castle Towers,’ alongside Himeji Castle and Matsuyama Castle, it’s not just the beauty of the keep that travelers should focus on. The ‘stone walls’ that appear underfoot and along the ramparts with every step are truly this castle’s deepest charm.
Wakayama Castle’s stone walls extensively utilize a bluish stone called ‘Kishu Aoishi’ (chlorite schist), which is rare nationwide. The sight of these stone walls, laid out like a gradient through different eras—from the early Nozura-zumi (a technique of stacking natural stones as they are) by Toyotomi Hidenaga, through the Asano period, to the elaborate stacking of the Tokugawa period—is truly breathtaking. The ruggedness of the blue stone and the weight of history create a beauty that will move even those who aren’t stone wall enthusiasts. However, please note that the surface of the blue stone can be slippery after rain or during humid times, so we highly recommend wearing comfortable walking shoes like sneakers for your stroll.
Within the vast grounds, there are endless attractions, including the diagonally built ‘Ohashi Roka’ (Covered Bridge Corridor), said to have been used only by the lord and his attendants, and the scenic ‘Nishinomaru Garden (Momijidani Garden),’ famous for its beautiful autumn leaves. Take your time to walk through the castle grounds with their varying elevations, and finally, from the top floor of the castle keep, enjoy a 360-degree panoramic view of Wakayama City, the Kinokawa River, and the distant sea, where you’ll surely experience a refreshing sense of accomplishment accompanied by a pleasant breeze.
Tomogashima Island
📍 Address: Kada, Wakayama, 640-0102, Japan
About a 20-minute ferry ride from Kada Port in Wakayama City, the uninhabited islands of Tomogashima (primarily Okinoshima), floating in the Kitan Strait, are the ruins of a fortress built by the former Imperial Japanese Army to defend Osaka Bay. After the war, the red-brick gun battery ruins, now swallowed by deep green foliage and moss, are truly like something out of ‘Castle in the Sky Laputa.’ It has become a unique scenic spot not only for anime fans and ruin enthusiasts but also for travelers seeking the extraordinary.
Several gun battery ruins are scattered across the island, but the main highlight is the ‘Third Gun Battery.’ The dimly lit underground passages of the ammunition depot and the massive ivy-covered brick structures strongly stimulate a sense of adventure (if you want to thoroughly explore the interior, it’s best to bring a flashlight rather than relying on your smartphone’s light).
Here’s a ‘conquering tip’ that travelers absolutely must remember: always follow the island’s walking route in a counter-clockwise direction (the route starting from the coastline). If you go clockwise, you’ll immediately reach the highest observation point after a strenuous uphill climb, which will severely deplete your energy and lessen the impact of the latter half of the journey. A counter-clockwise route allows you to gradually gain elevation while enjoying the beautiful coastline, the Second Gun Battery ruins, and the retro Tomogashima Lighthouse, culminating in a dramatic view of the Kitan Strait from Takanosu Mountain Observatory—the best possible experience. Please note that there are no restaurants or vending machines on the island, so bringing drinks and light snacks, and taking your trash with you, are essential.
Adventure World
📍 Address: 2399 Katata, Shirahama, Nishimuro District, Wakayama, 649-2201, Japan
When it comes to leisure in Wakayama, ‘Adventure World’ in Shirahama Town is an absolute must-visit. It’s a vast theme park that integrates a zoo, aquarium, and amusement park. Although the giant panda exhibition, a long-time symbol of the park, has ended, the park’s excitement and charm show no signs of fading.
An absolute must-experience attraction included with your admission ticket (1-day pass) is the ‘Kenya号 (Kenya Go)’ special train, which tours the safari zone. You can observe animals from herbivores to carnivores like lions and tigers up close, guaranteeing great excitement for all ages. The park is also constantly evolving, with the introduction of ‘Discovery Kenya Go’ in Spring 2026, an immersive experience that uses a 3D audio system to explore the secrets and abilities of animals through sound. Since different animals can be seen from the right and left windows, we recommend riding the Kenya Go train twice or combining it with a walking safari for a thorough observation.
Another major highlight is the ‘Marine Live’ show. The overwhelming scale of dolphins performing massive synchronized jumps to music is a spectacle rarely seen in other aquariums. This park is full of joy, offering the chance to find your ‘favorite’ among various animals besides pandas, such as penguins, Oriental small-clawed otters, and Amur tiger cubs.
Senjojiki
📍 Address: 2927-72 Shirahama, Nishimuro District, Wakayama, 649-2211, Japan
As a natural scenic spot in Shirahama tourism, ‘Senjojiki’ is popular alongside Sandanbeki. As its name suggests (‘A Thousand Tatami Mats’), vast white rock formations spread out like a sloping carpet towards the Pacific Ocean, as if a thousand tatami mats have been laid out. These rock formations were created from soft sandstone deposited on a shallow seabed approximately 18 to 15 million years ago, gradually eroded by countless crashing waves over immense periods. The greatest charm is being able to experience this natural sculpture-like beauty directly under your own feet.
While the contrast between the blue sea and white rock surface is beautiful during the day, our direct recommendation for travelers is ‘dusk.’ Selected as one of Japan’s Top 100 Sunsets, the sight of the rock formations dyed crimson by the light of the setting sun over the ocean is breathtakingly beautiful. It’s also a perfect location for wedding photos and portrait photography.
As a note of caution when visiting, strong winds often blow due to its coastal location, making warm clothing essential in mid-winter. Furthermore, there are no fences, and the rock surface is highly uneven, so heels or slippery shoes are extremely dangerous. Please bring comfortable sneakers and enjoy the dynamism of nature within safe limits.
Nachi Falls
📍 Address: Nachisan, Nachikatsuura, Higashimuro District, Wakayama, 649-5301, Japan
‘Nachi Falls,’ located in the Nachikatsuura area in southeastern Wakayama Prefecture, is one of Japan’s Three Great Waterfalls, alongside Kegon Falls and Fukuroda Falls. It boasts Japan’s greatest single drop of 133 meters as a straight waterfall (one that falls in a single stream without touching the rock face). What sets this place apart from being just a tourist destination is that the waterfall itself is enshrined as the deity of Hiro Shrine, a detached shrine of Kumano Nachi Taisha.
Upon arrival, you’ll notice that there’s no main shrine building. The ancient form of nature worship, where one directly gazes up at the great waterfall adorned with a shimenawa rope from the worship hall in front and offers prayers, remains strong here. The sight of the water cascading down with a roar and spray, like a white dragon descending from the heavens, emanates an overwhelming aura, making it a true power spot.
A strong recommendation for travelers is to pay the 300 yen admission fee and proceed to the ‘O-Taki Haisho Butai’ (Waterfall Worship Stage), located very close to the basin. There, you can fully immerse yourself in the waterfall’s power and negative ions. Additionally, along the way, you can partake in the ‘Goshinsui’ (sacred water) of the waterfall, believed to offer benefits for longevity (a dedicated cup can be purchased for 100 yen). Visit in conjunction with the World Heritage Kumano Kodo and Nachi Taisha, and experience a wonderful purification of mind and body in this sacred atmosphere.
Travel Tips to Enjoy Wakayama Tourism 120%
Wakayama Prefecture is very vast, and the areas introduced this time—’Wakayama City Area (Wakayama Castle, Tomogashima),’ ‘Shirahama Area (Adventure World, Senjojiki),’ and ‘Nachikatsuura Area (Nachi Falls)’—are quite far apart from each other. Trying to cram everything into a 1-night, 2-day trip will lead to exhaustion from constant travel. Therefore, it’s wise to narrow down your areas based on your travel purpose or plan a relaxed itinerary of 2 nights or more.
While a rental car offers overwhelming convenience for freedom of movement, taking the JR Limited Express ‘Kuroshio’ that runs along the coast, enjoying the ocean views from the train window, is also a recommended way to travel leisurely and experience a sense of journey. Wakayama, with its diverse facets of history, breathtaking scenery, and leisure, invites you to discover the deep charms of each spot and create unforgettable travel memories.
