Hiroshima Car Rental Self-Drive Tour: Spring Cherry Blossoms and Fall Maple Red Mountain Route and Cost Guide

The true value of renting a car in Hiroshima is not in the city attractions, but in its potential as the geographic center of the Chugoku region. From Hiroshima, you can connect Okayama, Yamaguchi, and Shimane prefectures in a single trip, experiencing the four seasons of inland mountain scenery—the flexibility that public transportation simply cannot offer.

Why Hiroshima is Worth Renting a Car

Hiroshima Station is an important stop on the Sanyo Shinkansen, but the real highlight is the self-drive radius extending from here. Public transportation can only take you to major station cities, while renting a car allows you to venture into mountainous areas, winding mountain roads, and remote onsen villages—the places where the most authentic scenery of the Chugoku region is found.

Especially in spring and fall, the Hiroshima car rental market shows clear off-season and peak-season differences. During the cherry blossom season (April-May) and maple season (October-November), daily rental rates are 30-50% higher than off-season, but this is also the most worthwhile time for self-driving in the surrounding mountain areas. If you can avoid Golden Week (late April-early October) and the autumn holiday (mid-late October), you can enjoy the same seasonal scenery with 20-30% lower rental rates.

Three Classic Self-Drive Routes

1. Okayama Direction: Korakuen Surrounding Mountain Area Loop (Half Day to One Day)

Drive east from Hiroshima to Okayama in about 1 hour, passing through the waterway scenery of the Kojima area. Korakuen itself doesn't require a special visit (too many tourists), but the northern Kibi Plateau mountain area is more worthwhile for self-driving. In spring, drive along Prefecture Routes 55 and 264 up to the plateau, passing through scattered farmlands and hinoki cypress forests; in fall, the same route has less crowded maple colors than Kyoto but with ample parking. Lunch can be at Takahashi City, where prices are 15-20% cheaper than Hiroshima. The round trip is about 150 km, with fuel costs of around ¥1,500-2,000.

2. Yamaguchi Direction: Karato Market + Tsunoshima Bridge + Inland Mountain Road (One Day)

This is my most recommended route. Drive southwest from Hiroshima to Shimonoseki in about 90 minutes—the fresh seafood at Karato Market is indeed worth a visit, but the key is the self-drive around Tsunoshima Bridge north of Shimonoseki. Yamaguchi Prefecture Route 276 winds along the coastline of Toyo Beach, not the fast highway feeling, but a speed where you can smell the sea breeze and see everyday fishing village life. Tsunoshima itself is a "check-in spot," but the inland mountain road north of Tsunoshima (Prefecture Route 493) is the secret of seasoned drivers—dense maple trees in fall, ample parking, very few tourists.

Return via inland mountain roads (Prefecture Route 437, National Route 191) through the hot spring villages at the Shimane border. The total route is about 280 km, taking 6-7 hours. In spring, the mountain cherry blossoms along this route bloom 2-3 weeks later than the plains, perfectly avoiding the crowds.

3. Shimane Direction: Izumo Taisha Surrounding Highland Loop (One and a Half to Two Days)

Drive north from Hiroshima to Shimane in about 2 hours—this route is often overlooked, but Shimane's inland mountains actually have Japan's most complete maple foliage resources. From Hiroshima, take National Route 54 north, and stay at an onsen ryokan in Miyoshi City (double room about ¥8,000-12,000/night, including dinner). The next morning, head to the area around Tamura Onsen upstream of the Hii River—the maple colors here far exceed those around Izumo Taisha in fall.

Izumo Taisha itself has poor transportation conditions (parking is far), but the advantage of renting a car is that you can stop at small shrines in the surrounding mountains—places like Usa Shrine and Yaegaki Shrine, which have historical depth and convenient parking. The round trip is about 320 km in total.

Car Rental Bases and Cost Planning

There are multiple car rental company offices at Hiroshima Station's North Exit. International driver's license recognition is 100% (bring your Taiwan driver's license with official translation and international license). Mid-March to mid-April and mid-October to mid-November are peak seasons. For a standard 5-passenger vehicle (Toyota Corolla class), daily rental is about ¥6,500-8,500; off-season (June-August, December-February) is about ¥4,500-6,000.

The increased car rental costs in spring and fall are closely related to global fuel price fluctuations. Recent geopolitical situations in the Middle East have driven up jet fuel costs, and rental companies' fuel supplement costs have also increased. Therefore, the price difference between off-peak and peak seasons is more pronounced than in previous years—if you're flexible with timing, the cost advantage of off-season self-driving is even greater.

Fuel Cost Estimate: Hiroshima city gas prices are about ¥150/liter, possibly ¥2-3 more expensive in remote mountain areas. For 200 km of self-driving per day, fuel consumption is about 5L, costing ¥750-800. Highway minimum one-way (Hiroshima-Okayama about 80 km) is about ¥2,000, round trip ¥4,000; if taking regular Prefectural Routes, fuel cost is ¥300-400 but travel time increases by 30-40 minutes.

Regarding parking, most mountain attractions have free parking—the only exception being well-known tourist spot parking lots (usually ¥500-1,000). In spring and fall, be sure to arrive early to secure a spot.

Practical Self-Driving Details

International License and Rental Process: Taiwan driver's license translations are accepted at major Hiroshima rental companies, but be sure to bring your passport. Rental insurance recommended is "Zero Deductible" (NOC Waiver Plan, about ¥1,000-1,500/day), because there are occasional scratches on mountain roads.

Fuel Habits: Japanese gas stations generally have shorter business hours than Taiwan. Mountain gas stations close around 6 PM, so plan ahead for evening and night self-driving. Highway service areas have more expensive gas, so refuel in towns.

Parking and Restrooms: During peak spring and fall seasons, popular attraction parking lots fill up by 9-10 AM. Depart at 6-7 AM. Almost all Japanese parking lots have restrooms, including mountain attractions, so no need to worry.

Navigation: Japanese navigation precision is world-leading. When renting a car, add an ETC card (automatic highway toll collection, no stopping, occasional discounts), or use Google Maps (offline maps work but mountain signal is unstable—download in advance).

Travel Tips

The key to mountain self-driving is departure time. In Japan, sunset is around 5:30 PM in March and 4:30 PM in November. Be sure to complete mountain climbs at least two hours before sunset, as visibility drops rapidly after dark in mountains.

If you can avoid Golden Week during spring rental, costs can save one-third with almost no difference in scenery—early April or mid-May actually has fewer crowds and better scenery. Fall maple forecasts are usually released in mid-September. Nationwide maple conditions are still light in early October, so不妨 wait until mid-late October for the perfect timing of lingering autumn colors and peak red foliage.

Finally, the core advantage of renting a car for self-driving is flexibility—if a particular mountain road has especially beautiful scenery, you can decide on the spot to drive a few more loops; if you spot a small shrine or onsen village, you can stop immediately. This mobility is something Hiroshima's extensive public transportation can never offer.
