Day 1: Fukuoka — Food Capital
Arrive in Fukuoka (Hakata), Kyushu's largest city and Japan's street food capital. Afternoon: explore Canal City Hakata's architecture, Ohori Park's lakeside paths, and the Hakata Machiya Furusato-kan folk museum (free) for local culture context. Evening: the city comes alive at yatai — outdoor food stalls lining the Naka River and Tenjin area. Each seats 8-10 people around a counter serving Hakata ramen (¥700), yakitori (¥150-¥300 per stick), gyoza (¥500), and oden. There are about 100 yatai across the city. Arrive by 7 PM for seats without long waits.
Tip: Yatai etiquette: sit down, order immediately (at least one drink), eat, and leave within 60-90 minutes. These tiny stalls depend on turnover. Credit cards rarely accepted.
Day 2: Beppu — Hell Valley
JR Sonic limited express from Hakata to Beppu (2 hours, ¥5,500 or JR Pass). Beppu produces more hot spring water than anywhere else in Japan — steam rises from across the entire city. Morning: tour the Jigoku (Hells) — seven dramatically colored hot spring pools too hot for bathing but spectacular to see. Umi Jigoku (ocean blue, ¥450) and Chi-no-Ike (blood red, ¥450) are the most impressive, or buy the all-Hells pass (¥2,200). Afternoon: actually bathe at Hyotan Onsen (¥820, 8 different baths) or the Beppu Beach Sand Bath (¥1,500 for sand burial). Stay overnight in Beppu.
Tip: Try an onsen-steamed meal at Jigoku Mushi Kobo in Kannawa — you cook eggs, vegetables, and seafood in natural steam vents (ingredients from ¥300, cooking free).
Days 3-4: Aso and Kurokawa Onsen
Day 3: Rent a car or take the bus to Mount Aso (2 hours from Beppu). Aso has one of the world's largest calderas — a vast grassland surrounded by five volcanic peaks. If the crater is open (check volcanic alerts), drive to the Aso Nakadake crater rim (¥600 including ropeway) to peer into the active smoking crater. Kusasenri meadow offers horseback riding (¥1,500) across emerald grasslands. Day 4: Drive to Kurokawa Onsen (1 hour from Aso) — a secluded hot spring village in a river gorge, consistently rated Japan's most atmospheric onsen town. Buy the onsen-hopping pass (¥1,300 for any 3 ryokan baths). Stay at a ryokan (from ¥15,000/person with meals).
Tip: Kurokawa's rotenburo (outdoor baths) are carved into the river gorge — surrounded by forest and moss-covered rocks. Visit 3-4 different ryokan baths to experience each unique setting.
Day 5: Kumamoto
Drive to Kumamoto (1.5 hours from Kurokawa) or train from Aso. Kumamoto Castle was one of Japan's greatest before the 2016 earthquakes — restoration is ongoing and viewing the massive reconstruction effort is fascinating. Enter the rebuilt main keep (¥800) for museum exhibits about the castle's samurai history. Walk Suizenji Garden (¥400) with its miniature Tokaido landscape. For lunch, try Kumamoto specialties: basashi (raw horse meat sashimi, ¥1,500), karashi renkon (mustard-stuffed lotus root, ¥400), and Kumamoto ramen with garlic chips (¥800). The city's mascot Kumamon is plastered everywhere.
Tip: The castle's curved stone walls (musha-gaeshi) were designed so samurai could not climb them — look for the impossible overhang that repelled attackers for centuries.
Days 6-7: Nagasaki
Day 6: Shinkansen from Kumamoto to Nagasaki (45 minutes on Nishi-Kyushu Shinkansen). Visit the Atomic Bomb Museum (¥200) and Peace Park — the museum is deeply moving and educational. Afternoon: Glover Garden (¥620) — Western mansions overlooking the harbor from the Meiji era when Nagasaki was Japan's window to the world. Evening: Inasayama night view (ropeway ¥1,250 return) — ranked alongside Hakodate and Kobe as Japan's finest. Day 7: Dejima — the artificial island where Dutch traders were confined for 200 years (¥520). Chinatown for champon noodles (¥900) — Nagasaki's signature dish of Chinese origin. Depart from Nagasaki Airport. Budget: ¥8,000-¥12,000/day.
