Getting to Iwakuni: Shinkansen, Flights & Transport from Hiroshima

Two Stations, One City: Understanding Iwakuni's Layout

Iwakuni has two stations that confuse first-time visitors, and understanding the difference is essential for planning your trip. Shin-Iwakuni Station (新岩国駅) is the Shinkansen stop, located on the outskirts of the city. Iwakuni Station (岩国駅) is the main city center station served by local JR Sanyo Line trains.

Kintaikyo Bridge — the reason most people visit — sits roughly between the two, about 5 kilometers from each. There is no direct train between the bridge and either station, so you will need a bus or taxi regardless of which station you use.

From Hiroshima to Iwakuni by Shinkansen

The fastest route from Hiroshima to Iwakuni is the Sanyo Shinkansen (山陽新幹線) Kodama service from Hiroshima Station to Shin-Iwakuni Station. The ride takes approximately 15 minutes.

Important: only Kodama trains stop at Shin-Iwakuni. The faster Nozomi and Hikari services skip this station entirely. If you board a Nozomi by mistake, the next stop could be Tokuyama or Shin-Yamaguchi — well past Iwakuni.

Fares from Hiroshima to Shin-Iwakuni are approximately ¥1,640 (~$11) for non-reserved seats and roughly ¥3,000 (~$20) for reserved seats. The Japan Rail Pass covers this route for non-reserved seating.

From Iwakuni Station by Local JR Train

An alternative is taking the JR Sanyo Line from Hiroshima Station to Iwakuni Station. This local train takes about 50 minutes and costs approximately ¥770 (~$5). It is slower but cheaper, and Iwakuni Station has more frequent bus connections to Kintaikyo Bridge than Shin-Iwakuni.

This option works well if you are already in the Hiroshima city center area or prefer to save on Shinkansen costs. The JR Sanyo Line is also covered by the Japan Rail Pass.

Getting from the Station to Kintaikyo Bridge

From Shin-Iwakuni Station (Shinkansen)

Iwakuni Bus (岩国バス) runs from Shin-Iwakuni Station to Kintaikyo Bridge. The fare is ¥350 (~$2.30) one way and the ride takes about 10 minutes. Buses run approximately 1-2 times per hour — less frequent than from Iwakuni Station.

The bus stop is right outside the station exit, by the park benches. For the return trip, board from Platform 3, located across from the bridge area. Many visitors on TripAdvisor note that English announcements are available on the bus.

From Iwakuni Station (Local Train)

Buses from Iwakuni Station to Kintaikyo Bridge run every 10-20 minutes, making this the more convenient option for connections. The fare is ¥300 (~$2) one way, and the ride takes about 15 minutes. The bus stop is directly in front of the station.

IC cards (Suica, ICOCA, PASMO, etc.) are accepted on Iwakuni buses. Board from the rear door and tap your card or pay cash when exiting at the front.

Getting Around Iwakuni: Buses, Taxis, and Walking

Once you reach the Kintaikyo Bridge area, most attractions are within walking distance. The bridge, samurai district, and ropeway to the castle are all clustered together, and you can cover them on foot in 3-4 hours.

If you need to move between the bridge area and either station, your options are:

• Bus: Cheapest option (¥300-350). Runs frequently from Iwakuni Station, less so from Shin-Iwakuni.
• Taxi: Available at both stations. Roughly ¥1,500-2,000 to Kintaikyo Bridge from either station. Practical for small groups splitting the fare.
• Walking: Possible but not recommended — 5 kilometers from either station, about an hour on foot with no particularly scenic route.
