Soy Sauce & the Southern Cape: Yuasa to Kushimoto — 2 Days

The old centre of Yuasa, a nationally designated preservation district of narrow lanes lined with dark-timber merchant houses, soy-sauce and miso warehouses, and a few shops and cafés, much as it looked in the Edo period when this was the prosperous home of an entire industry. Walking it you pass shopfronts where soy sauce, kinzanji miso and other ferments are still made and sold, the smell of the breweries in the air. It is small, atmospheric and almost entirely free of crowds.

Free to walk at any time; individual shops keep their own hours, generally daytime. The district is a short walk from JR Yuasa Station, about 30-40 minutes by train south of Wakayama City. Pick up a walking map at the station or the local visitor centre. Allow about an hour.

The oldest soy-sauce brewery still working in Yuasa, founded in 1841 and run by the same family for generations, fermenting soy sauce entirely by hand in great cedar barrels with no machinery, exactly as it was done in the town's heyday. A small adjoining museum of old tools and barrels explains the craft, and the shop sells the brewery's prized naturally brewed soy sauce. It is the heritage flagship of the whole town and the place to understand what makes Yuasa special.

Shop open roughly 09:00-17:00 (the small museum keeps similar daytime hours, sometimes weekends/limited days — confirm); free to browse. In the heart of the preservation district. Bottles travel well as a gift. Allow 30-40 minutes.

A working soy-sauce and kinzanji-miso maker just outside the old town with a visitor-friendly shop and café, where you can see the fermenting moromi mash, taste a range of soy sauces, and try the local curiosity of soy-sauce soft-serve ice cream. The café and shop also do a light lunch built around the house ferments — rice bowls, miso dishes and pickles. It is the easy, hands-on counterpoint to Kadocho's heritage, and a good place to taste before you buy.

Shop and café open roughly 09:00-17:00; a light lunch runs around ¥1,000-1,800 (approx., 2026). A short drive from the preservation district. The soy-sauce soft-serve is worth trying even if you eat elsewhere. From here it is a long but scenic drive south to Katsuura.

A vast, eccentric hot-spring hotel on a private headland at Katsuura, reached by the hotel's own boat across the bay, whose signature is the Bokido — a natural hot spring inside a sea cave, where you bathe in steaming water as the Pacific surges at the cave mouth. There are several other baths across the sprawling complex, including cliff-top and seaside springs. It is more of a hot-spring resort village than a hotel, and the cave bath is one of the most distinctive onsen experiences in Japan.

Stays include dinner and breakfast; rates vary by building and season (2026) — book ahead. Reached by the hotel ferry from Katsuura Port, near Kii-Katsuura Station. Note: the Nisshokan building is closed for renovation April 1-July 31, 2026 (its baths unavailable then), but the Bokido cave onsen and others remain open — confirm at booking. The cave bath has separate men's/women's hours.

Katsuura is one of Japan's leading ports for fresh (non-frozen) tuna, and the Nigiwai Ichiba market beside the harbour is where you can see the catch, watch tuna being cut, and eat an unbelievably fresh tuna bowl for breakfast looking over the boats. The early hours are the liveliest, with the morning auction happening next door. It is the authentic, working counterpart to the tourist fish markets elsewhere on the coast — come hungry and early.

Open early, roughly 08:00-15:00 (food stalls vary); a fresh tuna bowl runs around ¥1,200-2,500 (approx., 2026). By Katsuura Port, near Kii-Katsuura Station and the Hotel Urashima ferry pier. The tuna auction (viewable) is earliest in the morning. Cash easiest.

A line of some forty pointed rock pillars marching out to sea off the coast at Kushimoto, the eroded remains of a dyke of harder rock, set in a row so regular that legend has it the monk Kobo Daishi began building a bridge to a nearby island here. At low tide you can walk out among the nearer rocks; at sunrise the sun comes up directly behind the pillars in one of the south coast's great photographic moments. A roadside station beside it has food and parking.

Free, open at all hours; on Route 42 at Kushimoto, about 45-50 minutes by car southwest of Katsuura. Best at low tide or sunrise — check the tide table. The adjacent Michi-no-Eki has toilets, a shop and food. Allow 30-40 minutes.

Set on Japan's northernmost coral coast, where the warm Kuroshio current lets reef corals grow at this latitude, Kushimoto Marine Park combines an aquarium of local sea life with an undersea observation tower reached by a walkway out into the bay, where you descend below the surface to watch fish and coral through the windows without getting wet. There are glass-bottom boat trips too. It is a low-key, family-friendly stop that shows off the south coast's surprising marine richness.

Open roughly 09:00-16:30; admission around ¥1,800 adult (approx., 2026). On the coast at Kushimoto, a few minutes from Hashigui-iwa. The underwater tower depends on water clarity, best in calm weather. Allow about an hour.

The southernmost point of the main island of Honshu, a broad grassy headland dropping to cliffs above the open Pacific, with a white nineteenth-century lighthouse you can climb for a 360-degree horizon of nothing but sea. There is a viewing tower and a visitor centre, and on a clear day the curve of the earth feels close. Standing here, with the wind off the ocean and no land to the south until the far Pacific, is a fitting end to a journey through Wakayama's deep south.

Cape grounds free; the lighthouse has a small admission of around ¥300 to climb (approx., 2026), open roughly 09:00-16:30. At the southern tip of Kushimoto, a few minutes from the marine park. Windy and exposed — bring a layer. From here it is a long drive back north; plan your return accordingly.
