Yakushima 5-Day, 4-Night Itinerary : Jomon Sugi + Heart-shaped Cedar, Shiratani Unsuikyo Taiko Iwa, Half-Island Cycling, Traffic Controls & Onsen Tides

I built my Yakushima schedule with a “hard first, soft later” rhythm: finish the main objective (Jomon Sugi) in one decisive push on Day 2, use Day 3 (Shiratani Unsuikyo) to reset both body and mood, then spend Day 4 cycling a half-loop to store the island’s everyday texture into memory. The last day is reserved purely for leaving the island—so the trip doesn’t end as a scramble.

Quick Navigation


Where to Stay: Miyanoura vs Anbo (My Choice)

The two most common bases on Yakushima are Miyanoura and Anbo. If your core objective is Jomon Sugi (Arakawa Route), I recommend Anbo: your early-morning movement is smoother, and the overall friction cost is lower.

This trip, I stayed at Yakushima Sanso (in Anbo), which is very hiker-friendly: gear rentals are available, and they can help prepare a hiking bento. For a long day hike like Jomon Sugi, whether your gear and fuel are “already locked in on Day 1” often determines whether Day 2 feels stable—or anxious from start to finish.


Practical note: If you plan to do Jomon Sugi, don’t optimize for “prettiest hotel.” Optimize for “reducing your early-morning hassle.”

Day 1 | Fukuoka → Yakushima: Front-load the Risks

On arrival day, I scheduled almost no sightseeing. The reason is simple: Day 2 is a long-distance hike, and official guidance also emphasizes starting early to avoid having your return time compressed.


On Day 1, I only did three things:

  • Rest: sleep quality is priority #1

  • Prep: consolidate rain gear, headlamp, backup power, water, and trail snacks

  • Confirm food: don’t leave “what to eat” for dawn on a long hike day


Yakushima is famously described as a place where it “rains 35 days a month.” It’s not literal—it’s a shorthand for how frequent and persistent the rain is. Due to terrain effects and the Kuroshio Current, Yakushima’s rainfall level is among the highest in Japan. Bring proper rain gear.

Day 2 | Jomon Sugi (Arakawa Route): The Correct Way to Open a Stamina Battle

Access Control Must-Know: 3/1–11/30 Requires the Arakawa Hiking Bus

The standard Arakawa route to Jomon Sugi has seasonal traffic controls from March 1 to November 30. During this period, visitors must transfer near the Yakusugi Museum area and take the Arakawa hiking bus to reach the trailhead zone.

That’s why “starting early” is not a bonus—it’s the baseline strategy for a safer return.

Route Difficulty: Not Technical—Just Long

Japan’s World Natural Heritage information commonly describes the round trip to Jomon Sugi as a 9–10 hour day. For most people, it feels like a full-day distance effort.

The key capability here is not climbing technique. It’s:

  • pace control

  • fuel and hydration planning

  • avoiding a return that gets pushed into darkness


Signature Cedars and Landmarks Before Jomon Sugi (Including the “Heart Cedar”)

Many people treat Jomon Sugi as the only “destination,” but the route is actually a chain of protagonist-level ancient trees. Including these in your narrative also helps readers understand where they are along the hike.


1) Early section: Old Logging Railway Walk

The early segment follows an old logging railway, and the rhythm is relatively controllable. I deliberately did not rush here, because the stairs and undulations later are where the real energy cost begins.


2) The “Heart Cedar” Is Usually Wilson’s Stump

What many social posts call the “heart-shaped cedar” is typically Wilson’s Stump (ウィルソン株)—a massive Yakusugi stump.

The highlight is not the exterior. You have to walk inside. From within the hollow, look straight up: from a specific angle, the opening forms a heart-shaped outline. This spot is absolutely worth a pause—it gives you a strong “arrival moment” during a long day.


3) Daio Sugi and Meoto Sugi: A Shock Sequence Before the Finish

Along the way you’ll pass famous landmarks like Daio Sugi and Meoto Sugi. They expand your sense of scale before you even reach the end—making Yakushima’s giant-tree culture feel concrete, not conceptual.


4) Jomon Sugi: A Very Direct Sense of Completion

According to commonly cited references, Jomon Sugi is one of the largest confirmed Yakusugi trees. When you arrive, the satisfaction is real—you know you completed a route that required time and patience, not just “visited a spot.”


My Lesson: Fuel with a Schedule—Not with “Feeling”

On the return, I briefly felt dizzy. Later I realized I had packed my bento so deep that I forgot to eat.

On long hikes, fatigue and focus can dull hunger signals. By the time your body “reminds” you, it’s often already late. Use a timed schedule for fueling.

After the hike, I ate a local flying fish (tobiuo) dish. It wasn’t mind-blowing, but food wasn’t the point that night—recovery was.


Day 3 | Shiratani Unsuikyo → Taiko Iwa: The Healing Payoff of a Moss Forest

If Jomon Sugi was a “hard battle,” Shiratani Unsuikyo felt like recovery. You’re still walking in a forest, but your mindset shifts completely: Jomon Sugi is negotiating with time and stamina; Shiratani is stepping into a damp, quiet space where you can breathe slowly again.


Shiratani’s magic is its moss density and light quality. It’s often associated with the atmosphere of Princess Mononoke. One iconic spot is Moss-Covered Forest (苔むす森)—in this humid, rocky environment, moss spreads across nearly every surface, creating a visually powerful scene.


Which route should you choose?

Shiratani Unsuikyo has multiple route options, mainly differing by time and intensity:

  • Yayoi Cedar route: short and beginner-oriented (about 1 hour)

  • Bugyosugi route: medium duration (about 3 hours), with multiple Yakusugi landmarks

  • Taiko Iwa route: the most popular and complete option; crosses the moss forest and ends at a panoramic viewpoint


I chose the mainstream route: Shiratani Plaza → Taiko Iwa. Common figures place the round trip at about 5.6 km; time varies by pace, stops, photos, and conditions—typically about 4–6 hours.


Is Taiko Iwa worth it?

My answer: yes—because it gives you “closure.”Taiko Iwa is around 1,050 m in elevation and provides an open granite viewpoint. You transition from “close-up moss textures” to “distant ridgelines and forest scale.” The view opens up, and the route finally feels cleanly completed.


Trail note: It’s not hard—it’s wet

The challenge is usually not steepness; it’s slipperiness. Rocks, roots, and wooden steps can become slick with moisture. If water levels rise, parts of the trail may be restricted, so checking updates matters.

My baseline kit remained: hiking shoes + rain gear + waterproof storage. Treat these as standard, not optional.


Day 4 | Half-Island Cycling: Waterfalls Are the Background—Sunflower Fields Are the Point

On Day 4, I rented a bicycle and did a half-island loop. Yakushima’s roads are not flat—cycling is not “easy.” But when you slow down, the island becomes more dimensional: sea wind, salt in the air, light changes, and the sense of distance between small towns.

I passed several waterfall stops (e.g., Ryujin Falls, Senpiro Falls, and the Tōroki Falls viewpoint area). If you’ve seen many massive waterfalls, these may not feel shocking—but they work well as cycling checkpoints for water, breathing, and rhythm reset.

What I remembered longest wasn’t a major “must-see” stop—it was a sunflower field I happened upon. It wasn’t in my plan, yet it became the most typical solo-travel reward: while I was taking photos, a group of cheerful women approached and asked me to take a group photo for them.

They later realized I barely spoke Japanese—but instead of awkwardness, they leaned into clearer gestures and expressions. Positioning, angle, step closer, smile, one more shot—we did almost everything with body language, and everyone was laughing the entire time.

That moment made something very clear to me: solo travel is often not about how many spots you “complete,” but about the unplanned kindness that can change the mood of your entire day.


Hirauchi Kaichu Onsen: It’s Not “Arrive and Soak”—It’s “Check the Tides First”

Near the end of the cycling day, I went to Hirauchi Kaichu Onsen. The biggest trap here is timing: it only has a short bathing window around low tide. Official guidance notes:

  • Bathing is possible for about 2 hours before/after low tide (two windows per day)

  • The site is maintained by donations / a cooperation fee

  • Swimwear is not allowed

This time, I didn’t get in. Partly, I only fully understood the rules and atmosphere once I arrived; partly, there was a real sense of awkwardness. But I don’t regret it—standing by the shore, feeling the wind, watching the tide shift became a natural ending to the trip.


Day 5 | Leave Yakushima → Fukuoka: Keep the Final Day for Transit and Reset

On Day 5, I only handled the return. I strongly recommend this approach: if you cram sightseeing into the last day, you end Yakushima in a “rush.” But the best way to remember this island is to slow down.


Gear & Prep Checklist (Copy-Paste Ready)

  • Rain jacket + rain pants (Yakushima is wet; rain gear is baseline)

  • Headlamp (essential for early starts)

  • Water + trail snacks + hiking bento (eat on a schedule, not only when you feel hungry)

  • Waterproof storage (dry bag / pack cover)


Getting Around the Island: Buses “Are Not All the Same,” and Frequencies Are Low

Public transport on Yakushima is bus-based, but frequencies are limited. Many travelers choose to rent a car (if licensing documents allow).


1) Regular route buses: connecting port / airport / settlements along the main road

Yakushima has two bus operators (Yakushima Kotsu and Matsubanda Kotsu). Routes mainly run along the ring road. Key point: many attractions are not right next to stops—you may still need to walk. Know stop locations before you commit.


2) Dedicated scenic-route buses (different timetables): Shiratani Unsuikyo, Kigensugi

Official info separates these routes clearly: beyond the main road, there are routes to Shiratani Unsuikyo and Kigensugi, with separate schedules and possible weather-related changes.

Because schedules are limited, missing the last bus often means waiting or changing your plan.


3) Jomon Sugi access: Arakawa hiking bus / mountain shuttle (not the same as regular buses)

Jomon Sugi (Arakawa route) often requires special shuttle logistics. Official user info clearly warns:

  • Check schedules in advance to avoid missing the last bus—otherwise you may be forced to wait until the next morning.

  • Taxi supply on the island is limited and may not be immediately available.

  • One-way fares are listed in official guidance (e.g., 1,000 yen one-way tickets, etc.), along with purchase instructions. (town.yakushima.kagoshima.jp)

The risk of Jomon Sugi is not “whether you can finish the hike,” but whether you have enough buffer to return safely. Work backwards from the last bus time to decide your departure time.


4) Yakushima Bus Pass: How to Buy and Whether It’s Worth It (from 2025/10/1)

If you plan to rely mainly on public transport, the most practical ticket is the Yakushima Kotsu route bus Unlimited-Ride FREE PASS.

Important: this pass only applies to Yakushima Kotsu route buses (often identifiable by a palm-tree motif on the vehicle). It does not apply to other companies’ buses.
