Kyushu Road Trip: Hot Springs, Volcanoes and Coastal Towns

Planning the Route

Kyushu, Japan’s third-largest and southernmost main island, packs active volcanoes, the country’s highest concentration of hot springs, subtropical coastlines, and distinct regional cultures into an area roughly the size of Switzerland. A week-long road trip starting and ending at Fukuoka covers the highlights: south through Kumamoto and its restored castle to the volcanic caldera of Mount Aso, east to Beppu’s steaming onsen city, south to the mythological landscape of Takachiho Gorge, down to Kagoshima facing the erupting Sakurajima volcano, and back up the western coast through Nagasaki’s Portuguese and Dutch heritage.

Renting a car from Fukuoka Airport, which has counters for Toyota, Nissan, Orix, and Times car rental, provides the most flexibility. Automatic transmission is standard. GPS navigation systems with English language options are available at major rental agencies for 300 to 500 yen per day. Expressway tolls between major cities add up to several thousand yen per day, but the Kyushu Expressway Pass offers unlimited toll-road use for fixed periods. Gas stations are plentiful, and most accept credit cards.

Mount Aso and Central Kyushu

Mount Aso’s caldera measures 25 kilometers north to south and 18 kilometers east to west, making it one of the largest in the world. The active Nakadake crater emits sulfurous gas from a turquoise acidic lake visible from the crater rim when volcanic activity levels permit access. The ropeway to the crater rim was destroyed by the 2016 eruption, and access now requires a shuttle bus or a 30-minute walk from the parking area. Kusasenri meadow, a flat grassland inside the caldera, offers horseback riding with Aso’s volcanic peaks as backdrop.

Takachiho Gorge in Miyazaki Prefecture channels the Gokase River through narrow volcanic basalt cliffs dropping 80 to 100 meters, with Manai Falls cascading 17 meters into the gorge. Rental rowboats at 4,100 yen per 30 minutes allow paddling directly beneath the waterfall spray. Takachiho Shrine performs traditional kagura dances depicting Shinto myths every evening at 8 PM for 700 yen, including the famous tale of Amaterasu emerging from her cave to restore sunlight to the world.

Beppu and Southern Kyushu

Beppu produces more hot spring water than any other city in Japan, with eight distinct onsen areas and the Jigoku Meguri, seven hells where water boils at temperatures too hot for bathing. Umi Jigoku, the Sea Hell, displays a cobalt blue pool at 98 degrees Celsius where staff boil eggs in baskets for visitors to eat. Chinoike Jigoku, the Blood Pond Hell, runs red from dissolved iron. After the hells, the public baths of Beppu offer actual bathing: Hyotan Onsen provides multiple pools including a sand bath and waterfall bath for 750 yen.

Kagoshima faces Sakurajima across a four-kilometer bay, one of the most active volcanoes in the world that erupts hundreds of times per year, dusting the city with ash that residents sweep from cars and sidewalks as routine. The 15-minute ferry crossing runs 24 hours and costs 200 yen. Walking trails on Sakurajima pass buried torii gates submerged by the 1914 eruption’s lava flow. Sengan-en garden, the 17th-century Shimazu clan estate, uses Sakurajima as borrowed scenery across the bay, with traditional architecture and samurai-era gardens.

The Western Coast and Nagasaki

Nagasaki’s layered history encompasses Portuguese missionaries arriving in 1543, the Dutch trading post on Dejima island from 1641 to 1854, the Chinese merchant community, and the atomic bombing of August 9, 1945. The Atomic Bomb Museum presents the destruction’s human toll through artifacts and survivor accounts. Glover Garden preserves Western mansions on a hillside overlooking the harbor, including the home of Thomas Glover, a Scottish merchant who helped launch Japan’s industrialization and whose story may have inspired Madama Butterfly.

Nagasaki’s unique cuisine reflects its multicultural past: champon noodles in a pork bone broth with seafood and vegetables were created by Chinese residents, castella sponge cake originated from Portuguese bakers, and shippoku ryori combines Japanese, Chinese, and European dishes in a shared table format. Returning to Fukuoka from Nagasaki takes about two hours by car or two and a half by JR limited express. The Kunisaki Peninsula in Oita Prefecture, accessible as a detour from the Beppu area, preserves cliff-carved Rokugo Manzan Buddhist temples in a seldom-visited volcanic landscape.
