Arakawa Falls & Kanhizakura | Ishigaki's Only Waterfall, Natural-Monument Cherry & Access

“Ishigaki’s appeal is its beautiful sea and subtropical nature”—everyone knows that. But did you know that Ishigaki actually has a waterfall too? That is the island’s only waterfall, Arakawa Falls. A natural pool woven by an outstandingly transparent clear stream, in summer it’s beloved as a playground for local children and as a field for jungle climbing.

And the falls’ surroundings are a precious area designated a national Natural Monument as the “Arakawa Kanhizakura Wild-Growth Site.” The Kanhizakura (Taiwan cherry), said to be Japan’s earliest-blooming cherry, blooms pale pink flowers in Okinawa’s winter of January–February. In this article, we’ll deliver a complete guide to Arakawa Falls’ appeal, the Kanhizakura’s viewing season, access, and cautions.

What Kind of Place Are Arakawa Falls / Kanhizakura?

Arakawa Falls is Ishigaki’s only waterfall, in northern Ishigaki’s Yonehara area, between Kabira Bay and the Yonehara Yaeyama Palm Grove. In the midstream region of the Arakawa River flowing from Mt. Omoto, Okinawa’s highest peak, it’s composed of two tiers of falls, upstream and downstream.

The falls’ surroundings are designated a national Natural Monument as the “Arakawa Kanhizakura Wild-Growth Site.” An extremely precious area even in Okinawa, where about 300 Kanhizakura grow wild. You could call it “Ishigaki’s only spot where you can enjoy falls + cherry blossoms at the same time.”

The two falls, upstream and downstream

Arakawa Falls is composed of two places, upstream and downstream. We’ve compiled each one’s features.

Item	Downstream falls	Upstream falls
Height	About 3–4 m	About 10 m
Access	About 3-min walk from the parking lot	About 30-min stream-climb from downstream
How to play	Water play / Tarzan rope at the basin	Kanhizakura viewing, superb view
Difficulty	★★ (anyone OK)	★★★★ (for the strong-legged)

Only here in Okinawa | the Kanhizakura wild-growth site

The Kanhizakura (Taiwan cherry) is an early-blooming cherry distributed in Okinawa, Taiwan, and southern China. At the Arakawa Kanhizakura wild-growth site, about 300 Kanhizakura of about 6 m height and about 60 cm chest-height circumference grow wild, designated a national Natural Monument as an extremely precious natural grove even in Okinawa.

Now that most cherry wild-growth sites in the Ryukyu Islands have been lost, Arakawa is one of the few natural groves. In the January–February viewing season, you can meet a fantastical landscape of pale pink flowers scattered within the jungle.

Arakawa Falls Highlights and How to Enjoy It

Tarzan rope & water play at the downstream falls

Arakawa Falls’ downstream is a natural pool hugely popular with local children and tourists. A gentle waterfall of 3–4 m height, you can swim safely in the basin. The “Tarzan rope” tied to a tree (set up from over 40 years ago) is a specialty, and grabbing the rope and jumping into the basin is the standard way to play.

Ideal for the “salt rinse” (washing off seawater with freshwater) after playing at a summer beach too. There are tours where, after a Blue Cave tour or snorkeling at Yonehara Beach, you take a refreshing bath here.

Shower climbing to the upstream falls

For those confident in their physical strength, a course aiming for the upstream falls by stream-climbing (shower climbing) is recommended. The about-30-minute stream-climb isn’t that hard, but the adventure feel of proceeding through nature is full marks.

The upstream falls is a full-fledged waterfall of about 10 m height, and atop the falls a Kanhizakura wild-growth site spreads. Visit around February and you can enjoy a superb view seen only on Ishigaki—a waterfall with cherry blossoms dancing down.

January–February only | Kanhizakura viewing

The Kanhizakura is said to be Japan’s earliest-blooming cherry, blooming in late January–February, more than 2 months before the mainland’s Somei-yoshino bloom. Ishigaki’s Kanhizakura has paler flower color compared to those of the Okinawa main island and Amami-Oshima. Gentle pink flowers color the southern winter.

The caution is that the Kanhizakura are scattered along the Arakawa River. To view them you need to walk to the upstream, and outside the blooming period, finding them—looking like dead trees—is extremely difficult. It’s a spot you’ll definitely want to visit on a January–February trip.

Shower climbing / canyoning tours

The Arakawa Falls surroundings are the field for shower-climbing / canyoning tours held by local outdoor shops. Under the guidance of a specialist guide, you can have a full-fledged experience of ascending the stream to the upstream. Since equipment and safety management are thorough, even beginners can challenge it with peace of mind.

A hard-to-find place | the Kanhizakura monument is the landmark

Arakawa Falls is hard to see from the main road, a place easy to overlook. A stone monument written “Kanhizakura Wild-Growth Site” and the small parking lot beside it are the landmark. Heading north from Kabira Bay, passing Crystal Beach, it’s on the right side about 900 m past the “Yaeyama Kaya Soba” sign.

Go down the stairs from the parking lot, and it’s about a 3-minute walk through the trees to arrive at the basin. You can confirm the falls from the bridge called “Arakawa-bashi” too.

Cautions When Visiting Arakawa Falls

In get-wet-OK clothing

If swimming in the basin, bring a swimsuit / rash guard. If aiming for the upstream by stream-climbing, get-wet-OK shoes/clothes are essential. Don’t forget a towel and change of clothes either.

The footing is quite slippery

The rocks and grass near the mountain stream are very slippery. Rather than sandals, face it in grippy sneakers or marine shoes.

Watch for habu and bees

Ishigaki’s jungle has dangerous creatures like the habu too. We recommend not carelessly putting your hand into the bushes, and wearing long sleeves / long pants.

No restrooms/shop | advance preparation is needed

Arakawa Falls has no facilities at all, like restrooms, showers, vending machines, or shops. Prepare drinks, light meals, change of clothes and towels in advance before heading there. Dropping by the nearby “Tommy’s Bread” or “Yaeyama Kaya Soba” is recommended too.

Watch out for water damage to your camera

When playing in the basin, beware of water damage to your camera or smartphone. Using a waterproof case or a waterproof camera is safe.
