The JR Tokaido Shinkansen provides direct connections from Tokyo to Atami (40-50 minutes, around 4000 yen one way) and Mishima (45-60 minutes, around 4500 yen one way) at the entrance to the Izu Peninsula. The journey is covered by the Japan Rail Pass, but not by the JR Tokyo Wide Pass.
Limited express trains, named "Odoriko" and "Saphir Odoriko", connect Tokyo via Atami (80 minutes, around 3500 yen) and Ito (100 minutes, around 4000 yen) with Shimoda (160 minutes, around 6500 yen) in the south of the Izu Peninsula. In Tokyo, most trains use Tokyo Station, while a few use Shinjuku Station. Shimoda's railway station is called Izukyu-Shimoda Station.
"Saphir Odoriko" trains carry only Green Car and Premium Green Car seats (Premium Green Car seats are not covered by the Green Car version of the Japan Rail Pass) and require advance reservations, while "Odoriko" trains carry ordinary and Green Car seats, including some non-reserved ordinary seats.
Note that between Ito and Shimoda, these limited express trains are running on the tracks of the Izukyu Railway, which means that Japan Rail Pass holders will have to pay a supplement fee when traveling along this section. The one way supplement fee for the journey between Ito and Shimoda is 2660 yen. In contrast, the journey is fully covered all the way to Shimoda by the JR Tokyo Wide Pass thanks to an exception to the rule.
Some Odoriko trains carry a few wagons which are separated from the rest of the train at Atami Station and continue to run via Mishima Station to Shuzenji Station. The one way journey from Tokyo to Shuzenji by direct Odoriko limited express train takes two hours and costs about 4500 yen.
Note that between Mishima and Shuzenji, the Odoriko limited express is running on the tracks of the Izuhakone Railway Company, which means that Japan Rail Pass holders will have to pay a supplement fee of 550 yen when traveling along this section. On the train journey to Shuzenji, the JR Tokyo Wide Pass is not valid beyond Atami.
It is also possible to access the Izu Peninsula by local trains along the JR Tokaido Line. The one way journey from Tokyo to Atami takes about 100 minutes and costs 1980 yen. To Mishima it takes about two hours, costs 2310 yen and usually requires a transfer of trains at Atami Station.
If you are based in Shinjuku, you could save a few yen by taking the Odakyu Railway from Shinjuku to Odawara and transfer to the JR Tokaido Line there. The whole journey to Atami would take more than two hours but cost only 1330 yen. To Mishima it would take about 2.5 hours and cost 1590 yen.
Above fees and schedules are subject to change. Be sure to check current yen exchange rates.
The Izu Peninsula is served by two railway lines and a relatively efficient bus network. It is also a suitable region of Japan to be explored by rental car, motorcycle or bicycle. Please see the individual pages about Shimoda, Ito and Atami for further access and orientation details.
The JR Ito Line leads from Atami to Ito, from where the Izukyu Line continues further south to Shimoda. Note that Shimoda's railway station is called Izukyu-Shimoda Station. There are roughly two local trains per hour that run all the way between Atami and Shimoda in each direction plus a few Odoriko limited express trains to/from Tokyo. The one way journey from Atami to Shimoda by local train takes about 90 minutes and costs 2210 yen. By limited express train it takes about 70 minutes and costs 3770 yen.
Because the railway tracks south of Ito are owned by Izukyu Railway, holders of the Japan Rail Pass and JR East Pass have to pay a supplement when using this section. The supplement between Ito and Shimoda is 1860 yen on local trains and 2660 yen on limited express trains (one way). Only the Tokyo Wide Pass covers also the trains between Ito and Shimoda.
The other railway line serving the Izu Peninsula is the Izuhakone Line from Mishima to Shuzenji. There are departures every 10-20 minutes in each direction. The one way journey takes 35 minutes and costs 550 yen. JR passes are not valid for this trip.
Tokai Bus operates a dense and relatively efficient bus network that covers most of the Izu Peninsula and is centered around the major railway stations, including Atami, Ito, Shuzenji and Shimoda. The fare is proportional to the distance traveled and is paid when exiting the bus. The ten major IC cards, including Suica, Icoca and Pasmo, are accepted on Tokai buses.
Tokai Bus also offers a variety of bus passes for the different areas of the Izu Peninsula. In addition to unlimited use of buses, many also include discounted admission to selected attractions within the areas covered. Some of the most useful passes include:
Exploring the Izu Peninsula by rental car can be very pleasurable and efficient. Rental car outlets can be found near many major railway stations, such as Mishima, Atami, Ito, Izu Kogen, Shuzenji and Shimoda. Driving from Atami Station to Cape Irozaki takes about 2.5 hours.
Like around most of Japan, the roads on the Izu Peninsula are well maintained and drivers are relatively considerate. However, traffic jams along the peninsula's eastern coast are not unusual on weekends and during holidays. Traffic along the western and southern areas of the peninsula tends to be much lighter.
Due to the mountainous terrain of the peninsula, many inland roads have steep and winding passages, including the Izu Skyline and Nishi-Izu Skyline, two toll roads with spectacular views of the surrounding scenery.
