Japan overland

By the Viamo editorial team · Editor Terje Moy · Last updated July 2026 · 6 min read

Japan stretches nearly 3,000 kilometres from the icy northern tip of Hokkaido to the subtropical islands of Okinawa. You cannot cross it all without at least one ferry, but the combination of Shinkansen, express trains, local railways and inter-island boats makes a full length-of-Japan journey one of the world's great slow-travel experiences. Here is how to think about it.

The shape of the journey

Japan consists of four main islands — Hokkaido, Honshu, Shikoku and Kyushu — plus thousands of smaller ones, including the Ryukyu chain that stretches south toward Taiwan. The Shinkansen bullet-train network spans most of Honshu, extends into Kyushu and, as of 2016, reaches Hokkaido via the undersea Seikan Tunnel to Shin-Hakodate-Hokuto. Shikoku has no Shinkansen but is well served by limited-express trains.

A classic overland route runs roughly: Sapporo → Tokyo → Kyoto/Osaka → Hiroshima → Fukuoka/Hakata, then by ferry or bridge south through Kyushu. For the full length including Hokkaido and Okinawa, you need to add ferries at the far ends.

Hokkaido: the far north

The northernmost of Japan's four main islands is reached from Tokyo by Shinkansen — the Hokkaido Shinkansen runs through the Seikan Tunnel (the world's longest undersea railway tunnel) to Shin-Hakodate-Hokuto, from where limited-express trains continue north to Sapporo. Total journey time from Tokyo to Sapporo is around 8 hours by the current combination. A new Shinkansen extension to Sapporo is under construction and expected to eventually cut this significantly.

Sapporo is the capital of Hokkaido and a natural base: the city is large, well-connected and has an easy-to-use subway. From here, local trains and buses reach Otaru, Noboribetsu, Furano and the national parks of central Hokkaido. If you are doing the full length of Japan, you would start here before heading south.

For the very northernmost point accessible by rail, the journey reaches Wakkanai at the tip of Hokkaido by limited express — the northernmost railway station in Japan.

The Shinkansen spine: Hokkaido to Kyushu

The Shinkansen network connects the four main islands (via Honshu) and is the fastest way to cover large distances. Key legs on a northsouth journey include:

• Hakodate → Tokyo: about 4 hours by Hokkaido/Tohoku Shinkansen.
• Tokyo → Kyoto: about 2 hours 15 minutes by Tokaido Shinkansen (Nozomi services; passes may require the slower Hikari).
• Kyoto → Hiroshima: about 1 hour 20 minutes (Nozomi) or around 1 hour 50 minutes (Hikari).
• Hiroshima → Fukuoka/Hakata: about 50 minutes (Nozomi) — crossing into Kyushu through the undersea Kanmon Tunnel.

A Japan Rail Pass (sold to overseas visitors, available through Eurail and authorised agents) covers most Shinkansen and JR express services but not the Nozomi or Mizuho fastest services. For a length-of-Japan journey, the pass typically saves money compared with individual tickets. Calculate your itinerary before buying — the pass comes in 7, 14 and 21-day versions.

Slow detours: the local railway way

Between Shinkansen stops, Japan's dense network of limited express and local trains lets you take the longer, slower road. Some highlights for the length-of-Japan traveller:

• The Tohoku region (between Tokyo and Hokkaido) rewards slower exploration: Sendai, Aomori and the Nebuta Matsuri festival route are all on the JR Tohoku main lines.
• Kinosaki Onsen, Tottori and the San-in Coast (facing the Sea of Japan) are served by limited expresses on Honshu's quieter north coast — a slower but beautiful alternative to the Sanyo Shinkansen corridor on the south.
• The Shimanami Kaidō cycling route across the Seto Inland Sea bridges links Honshu and Shikoku for cyclists and pedestrians — a detour of genuine beauty.
• Kyushu has its own Shinkansen (Kyushu Shinkansen, Fukuoka to Kagoshima) plus scenic steam-train excursions and limited expresses through mountain valleys.

Shikoku: the fourth island

Shikoku is the smallest of the four main islands and the one most often skipped on a quick transit. It has no Shinkansen, but limited-express trains (the Anpanman trains are a quirky delight) and local lines cross its mountains and coasts. Shikoku is reached from Honshu by bridge (the Seto-Ōhashi Bridge, from Okayama, carries both trains and cars) or from Kyushu by ferry. The island is famous for the Shikoku Pilgrimage (88-temple circuit), and its rural quietness contrasts pleasantly with the pace of Honshu.

Crossing to Okinawa: the southern ferry

The Ryukyu Islands, including Okinawa, are not connected to the main islands by rail or road — they are reached by air or by ocean ferry. Arimura Sangyo and Marix Line operate overnight ferry services between Kagoshima (the southernmost large city on Kyushu) and Naha (Okinawa's capital), with the crossing taking around 25 hours. The ferry calls at several Amami islands along the way. It is slow travel in the truest sense — a full day at sea — and popular with travellers and motorcyclists who want to bring vehicles south.

The southernmost inhabited islands of the Ryukyus are reached by smaller ferries and island-hop connections from Naha. For most overland travellers, Kagoshima to Naha by overnight ferry is the natural southern endpoint.

Practical planning

A Japan Rail Pass is the practical backbone for a length-of-Japan journey. The 21-day pass is sufficient for most travellers covering the full route at a reasonable pace; a 14-day pass works if you are moving fast and prioritising Shinkansen. Activate it when you actually start using it — you choose the start date.

For accommodation, Japan has a wide range at every budget: business hotels near stations, traditional ryokan (inn with futon and kaiseki meals) in smaller towns, and capsule hotels in cities. Booking a few nights ahead in popular areas (Kyoto above all) is wise, especially in cherry-blossom and autumn-foliage seasons when accommodation fills months in advance.

The IC card (Suica or ICOCA) is your friend for all local transport that isn't covered by the rail pass — urban metros, local buses, convenience store purchases. Load it on arrival.

For context on planning a full rail journey, see the Viamo flightless travel guide and the US rail guide for comparison.

How long does it take?

A bare minimum to cover the Shinkansen spine from Hokkaido to Kyushu would be around 10 days, moving fast. A rewarding journey that includes Hokkaido, the Tohoku region, Tokyo, Kansai (Kyoto, Osaka, Nara), Hiroshima, Shikoku and southern Kyushu realistically needs three to five weeks. Adding Okinawa means at least another three to four days for the ferry each way.

Frequently asked questions

Do I need a Japan Rail Pass for this journey?

Not strictly required — you can buy individual tickets — but for a length-of-Japan journey covering multiple long Shinkansen legs, the pass almost always saves money and simplifies travel considerably. Calculate your route's total ticket cost against the pass price before buying.

Can I bring a bicycle on the Shinkansen?

Yes, with restrictions. Bicycles must be fully folded and bagged (a rinko bag) and stored in the overhead luggage area or the dedicated space at the end of certain carriages. Advance planning is needed for a cycling-rail combination.

Is the Seikan Tunnel the only way to Hokkaido by land?

Yes, currently. The only fixed-link to Hokkaido is the Seikan Tunnel, used by the Hokkaido Shinkansen and some freight trains. There is no road crossing; driving to Hokkaido requires a ferry from Honshu (several operators connect Aomori, Sendai and Tokyo with Hakodate and Tomakomai).

How do I reach Okinawa without flying?

By overnight ferry from Kagoshima. Operators including Arimura Sangyo and Marix Line run regular departures, with the crossing taking around 25 hours. The ferry is comfortable with different cabin classes, and the island-hopping stop at the Amami Islands is a bonus.
