Akashi Kaikyo Bridge

Awaji Island (淡路島 Awajishima) is a not-terribly-large island - about the same size as Singapore - that marks the eastern boundary of the Seto Inland Sea of Japan. Thanks to a set of new bridges and a cross-island expressway, most visitors just zip through on their way from Honshu to Shikoku.


The island is occupied by three cities: Awaji, Sumoto and Minami-awaji.


Awajishima has some claim to being the oldest settled area in Japan; the Kojiki mentions it under the name "Onokoroshima" and burial mounds (kofun) dating back thousands of years have been found on the island. The ningyo joruri puppet theater, which has evolved into bunraku, seems to originate from Awajishima.

Awajishima made a very unusual but brief appearance on the world stage as the epicenter of the Great Hanshin Earthquake of 1995 that killed over 6000 people. However, Awajishima was (and remains) far less built up than the suburbs of Kobe across the bay, which took the brunt of the damage. It was also the island where the England soccer team stayed during the World Cup in 2002.


The southern tip lies a mere kilometer off the coast of Shikoku, and a bridge now straddles the Naruto Strait, famed for the whirlpools that form as the tide flows in and out. The very name "Awaji" means "road to Awa", the former name of current Shikoku prefecture of Tokushima.

At the other end of the island, some 50 km away, the northern tip is not far from the port city of Kobe on Honshu, and the immense 3.9 km Akashi Kaikyo Bridge — the world's longest until 2022 — now connects Awaji to the mainland. Politically (and in geographic terms somewhat oddly), despite its proximity to Shikoku, Awaji is a part of Honshu's Hyogo prefecture.

Tourist information site[edit]

The local tourist association has a multilingual guide site.

Get in[edit]

Map of Awaji Island

By plane[edit]

  • Highway buses connect Kobe Airport and Sumoto four times daily (two hours, ¥2000).
  • (Awaji-Kanku Line, ferry line between Sumoto and Kansai International Airport was discontinued in 2018.)

By car[edit]

The inter-island expressway will get you from Akashi to Naruto, but it isn't advised unless you're willing to part with ¥5000 in tolls. Furthermore, signage is in Japanese and may be incomprehensible to a foreigner.

By bus[edit]

A more affordable option than private cars are highway buses, which charge around ¥600 for crossing the bridge and ¥1800 for a one-way trip from Kobe to Sumoto.

By train[edit]

There are no direct train services to Awaji Island. Highway buses run directly from major train stations, such as Shin-Kobe on the shinkansen (¥1800 to Sumoto), and Osaka and Sannomiya stations on the regular JR line (¥2300 and ¥1800 to Sumoto, respectively). From Shin-Osaka station you must either take a local train one stop to Osaka station, or remain on the shinkansen to Shin-Kobe, to transfer to the bus.

Buses to Awaji Island are not valid with the Japan Rail Pass. Tickets can be purchased from "Midori-no-Madoguchi" locations at each station.

By ferry[edit]

Even cheaper and more scenic, but available for the northern crossing only, are ferries that cross from Akashi to Iwaya for ¥450 (13 minutes) via the Jenova Line located south of JR Akashi Station.

Get around[edit]

Public transport is limited to very occasional buses. Awaji Kotsu (English page) site has its bus routes on the island (Japanese). Unusually for Japan, there are no trains on the island. If you don't have your own set of wheels, hitchhiking is a viable option.

Check out the beaches, especially on the more sparsely settled northern coast. They're a popular nearby summer getaway for Kansai-ites. There are also a number of hot springs (onsen), the best known of which are Awaji's largest town Sumoto and the mildly radioactive (!) waters of Iwaya adjacent to the northern bridge.

Today's Awajishima is known primarily for its bridges and onions. The current total population hovers around 150,000, and (unlike most rural areas in Japan) is slowly on the rise due to the improved connections to the mainland. Scattered here and there are a number of herb and biwa (loquat) farms. The southern coast has a hideous but huge concrete statue of the Buddhist deity Kannon and the inevitable Onokoro Amusement Park.

  • 1 Akashi Kaikyo Bridge (明石海峡大橋, Akashi Channel Bridge) (Take JR Kobe Line and get off at Maiko Station.). Completed in 1998, this majestic bridge dwarfs the village of Iwaya below. The bridge's total length is 3,991 m, and the main span's length of 1,991 m made it the longest suspension bridge in the world (surpassed by Çanakkale Bridge in 2022). The bridge is attractively lit at night.
  • 2 Naruto Whirlpools. See the whirlpools, either at the rest area on the expressway near Onaruto Bridge or by cruise. These are a major attraction for the Japanese, and manga character Naruto Uzumaki (lit. "whirlpools of Naruto") is named after them, but most visitors will find them distinctly underwhelming. Visit during the changing of the tides (four times daily) to see them at their largest.
Sumoto Castle
  • 3 Sumoto Castle (洲本城 Sumoto-jō). A ruined castle and keep. It is the oldest reconstructed castle in Japan, having been rebuilt prior to WWII in 1928. Getting there requires quite a hike, but the view from the top is extraordinary.
  • 4 Water Temple (本福寺水御堂). 09:00-17:00. A famous Buddhist temple building designed by Japanese architect Tadao Ando. The same architect also designed nearby Yume no Butai. ¥400.
  • 5 Nojima Fault Preservation Museum (北淡震災記念公園), +81 799-82-3020. A section of the Nojima Fault, responsible for the 1995 Great Hanshin earthquake, is preserved here.
  • 6 Kiseki no Hoshi Botanical Museum (奇跡の星の植物館) (Connected to the Westin Hotel.), +81 799-74-1200. A beautiful botanical museum.



Awaji is famous for their onions, fish and cheese.



Awaji has a scattering of ryokan and minshuku, concentrated in the hot spring areas. There are also a number of campsites, especially on the less populated western coast.

  • 1 Hamabesō (浜辺荘) (AT the foot of the Akashi Kaikyo Bridge, about 20 min on foot from Iwaya Port), +81 799-72-4755. A typical quiet minshuku. ¥5500 with breakfast.
  • 2 The Went Awaji (ウエント淡路東海岸) (in Aiga on the east coast), +81 799-28-0283. A nice hotel and resort. Pool, spa, fine dining and other necessities.
  • 3 Westin Hotel Awaji (ウェスティンホテル淡路), +81 799-74-1111. Check-in: 15:00, check-out: 11:00. A giant beautiful hotel with many activities around it. It's located in the north-eastern part of the island and is easily accessible by bus.
