Discovering Mukaishima: The Ultimate Beginner’s Guide to Cycling the First Jewel of the Shimanami Kaido

For many travelers, the Shimanami Kaido is a bucket-list endurance challenge—a 70-kilometer odyssey across six islands and six massive bridges spanning the Seto Inland Sea. But for those who want the sea breeze and the cinematic “retro-Japan” aesthetic without the leg-numbing climbs, the journey begins and often finds its heart on Mukaishima. Located just a stone’s throw across the narrow Onomichi Channel, Mukaishima serves as the gateway to this world-famous cycling route. It is an island of contrasts: rugged shipyards and industrial heritage on its northern shore, and sleepy citrus groves, hidden beaches, and artisanal chocolate shops on its southern coast.

Whether you are a seasoned cyclist or someone who hasn’t touched a bike since childhood, Mukaishima offers a condensed version of everything that makes the Setouchi region magical. In 2026, as slow travel and sustainable tourism continue to define the Japanese travel landscape, Mukaishima stands out as the perfect “test drive” for the Shimanami Kaido. This guide is designed to help beginners navigate the island with ease, ensuring you find the best views, the tastiest local treats, and the most stress-free paths through this island paradise.

1. Starting Your Journey: The Onomichi to Mukaishima Ferry

The first rule of cycling Mukaishima for beginners is a surprising one: **do not cycle across the Onomichi Bridge.** While the bridge exists, it is narrow, lacks a dedicated cycling lane for much of its span, and involves a steep, unpleasant climb through heavy traffic. Instead, do as the locals do and take the ferry.

The ferry ride from Onomichi to Mukaishima is one of the shortest and most charming commutes in the world. Several lines run frequently (every 10-15 minutes) from piers near the Onomichi Station and the Green Hill Hotel. The ride takes approximately five minutes and costs about 110 yen per person (plus 10 yen for your bike).

As the ferry pulls away from the mainland, you get a panoramic view of Onomichi’s hillside temples and the bustling shipyards of Mukaishima. It’s the perfect moment to check your gear and breathe in the salt air. Once you disembark at Mukaishima’s Ekimae Pier, you are officially on the “Blue Line”—the painted navigational marker on the road that guides cyclists all the way to Imabari.

2. The Beginner-Friendly Route: Coastal Charms and Flat Paths

Mukaishima is roughly 20 kilometers in circumference, but beginners should focus on the southern and western coasts. The northern side of the island is dominated by heavy industry and shipyards. While fascinating in its own right, the southern side offers the scenic, tranquil “island life” most visitors are looking for.

From the ferry pier, follow the Blue Line westward. The path is almost entirely flat for the first few kilometers, hugging the coastline. You’ll pass through small residential neighborhoods where old wooden houses stand alongside modern gardens. Keep an eye out for the “Cycling Oases”—designated rest stops where you can pump your tires, use the restroom, or simply refill your water bottle.

The highlight for beginners is the stretch along the southern coast heading toward the Innoshima Bridge. Here, the road opens up to reveal the sparkling Seto Inland Sea, dotted with tiny uninhabited islets. The traffic is minimal, allowing you to cycle side-by-side with a companion while enjoying the rhythmic sound of the waves. This section perfectly encapsulates the “Slow Setouchi” vibe, making it ideal for those who want to take photos every few minutes.

3. Retro Vibes and Sweet Stops: Where to Refuel

No cycling trip in Japan is complete without “tabearuki” (eating while walking, or in this case, cycling). Mukaishima has earned a reputation as a foodie’s island, blending nostalgic Showa-era charm with modern artisanal shops.

Goto Soda (Goto Seiryosho):

A visit to Mukaishima is incomplete without stopping at this legendary local soda factory. Operating since the mid-20th century, Goto Soda produces refreshing beverages in classic glass bottles. Their “Ramune” and “Cider” are staples, but the local favorite is the “Marushima” cider. Sitting on a wooden bench outside the shop, sipping cold soda from a vintage bottle, feels like stepping back forty years into Japan’s past.

Ushio Chocolatl:

Perched on a hill overlooking the sea, this artisanal chocolate factory is a favorite for visitors. Note for beginners: the climb up to the shop is steep! If you aren’t feeling confident in your climbing legs, it is perfectly acceptable to walk your bike up. The reward is a selection of single-origin chocolates and a spectacular view of the islands. Their packaging, designed by local artists, makes for a perfect souvenir.

Willows Coffee:

If you need a caffeine hit, this stylish roastery near the beach offers high-quality coffee in a relaxed atmosphere. It’s a great place to chat with other cyclists and gather intelligence on the road conditions ahead.

4. Cultural Highlights and Natural Beauty

Mukaishima isn’t just a transit point; it’s a destination with its own unique landmarks. For a touch of nature, head to the **Mukaishima Orchid Center**. Even if you aren’t a botany enthusiast, the vast greenhouses filled with vibrant tropical flowers offer a peaceful reprieve from the sun.

For those interested in the cinematic history of Japan, Mukaishima has served as a filming location for several famous movies, including works by the legendary director Nobuhiko Obayashi. The island’s “Old Cinema” feel is palpable in its narrow alleys and weathered stone walls.

If you’re visiting in the warmer months, **Tachibana Beach** is the place to be. This sandy stretch on the south side of the island is perfect for a quick dip or a picnic. The water in the Seto Inland Sea is remarkably calm, making it much safer and more relaxing than the rougher Pacific coast. From here, you can see the majestic Innoshima Bridge looming in the distance—the first major bridge of the Shimanami Kaido. Even if you don’t plan to cross it, cycling to its base offers a sense of the immense scale of the engineering project.

5. Practical Tips for a Stress-Free Ride

Cycling in a foreign country can be intimidating, but Mukaishima is designed with hospitality in mind. Here are a few practical tips to ensure your beginner’s trip goes smoothly:

**Rental Options:** If you aren’t bringing your own bike, the Onomichi Port Rental Cycle terminal is the most convenient. They offer a range of bikes, from cross bikes to city cycles (mamachari). In 2026, e-bikes are more popular than ever and are highly recommended for beginners to handle the occasional bridge ramp or hill.

**The Blue Line:** Look at the ground! A thick blue line is painted on the side of the road. If you follow this line, you cannot get lost. It leads you through the safest, most efficient route for cyclists.

**Bridge Access:** If you decide to leave Mukaishima for the next island (Innoshima), remember that the “entrance” to the bridge is usually a long, winding ramp (the “loop-de-loop”). These are designed with a gentle 3% grade, making them manageable for beginners, but they do require a bit of stamina.

**Weather and Attire:** The Setouchi region is known for its “Fine Weather Kingdom” status, but the sun can be intense. Wear sunscreen and a hat. Conversely, the sea breeze can be chilly in the spring or autumn, so a light windbreaker is essential.

**Cash is King:** While Japan is becoming more digital, many of the small soda shops and fruit stands on Mukaishima still only accept cash (Yen). Keep a coin purse handy for the ferry and snacks.

6. Beyond the Bike: Exploring Local Life

While cycling is the main draw, taking time to “park and walk” will reveal the true character of Mukaishima. The island is famous for its citrus—lemons, hassaku oranges, and mikan. In the winter and spring, you’ll see trees heavy with bright yellow and orange fruit. Many farmers set up “unmanned stalls” where you can buy a bag of fresh citrus for a few hundred yen, leaving your coins in a small wooden box.

The local shipyards also offer a unique cultural context. The Setouchi area is one of Japan’s most important shipbuilding hubs. Seeing a massive container ship being repaired just a few meters from a quiet orange grove is a quintessential Mukaishima experience. It reminds travelers that this isn’t just a tourist park; it’s a living, working community with a deep connection to the sea.

For dinner after your ride, head back to Onomichi or find a local “Okonomiyaki” shop on the island. The “Onomichi-style” Okonomiyaki often includes chicken gizzards (sunazuri) and squid tempura (ikaten), providing a savory, filling end to a day of physical activity.
