Itoshima is a car trip
that tolerates a train.

Itoshima is not a town. It's a 30-kilometre coastline with the good bits spread along it and one railway that doesn't go there.

The train gets you to Chikuzen-Maebaru, which is the administrative middle of nowhere. The torii, the beaches, the cafes and the oyster huts are all strung along the coast road beyond it, connected by a Showa bus network that runs often enough for locals and not often enough for a visitor with a return train to catch. Buses cost ¥410–510 (~$2.70–3.40) per hop and a day pass at around ¥1,000 (~$6.65) covers unlimited coastal rides — buy that, not singles. The last useful return bus is around 18:00, which collides directly with the sunset that is the entire reason people come.

Bikes are the good car-less answer and they have their own trap: rental near Maebaru runs about ¥1,000 (~$6.65) a day for a basic mamachari or ¥1,500 (~$10) for four hours on a cross bike, and they sell out — arrive by 09:30. Maebaru to Sakurai Futamigaura and back is roughly 25 km with real hills in places, which is a pleasant half-day on a decent bike and a grim one on a shopping bike with a headwind.

Renting a car in Fukuoka city and driving out — about 50 minutes — is what locals and most Japanese visitors do, and inventory at Maebaru itself is thin, so book the city branch. For four people, a private charter with a driver works out close to the price of four coach seats and is dramatically better here than anywhere else on the day-trip list. Say it plainly: Itoshima is a car destination that tolerates train, bike and bus. Plan accordingly and it's lovely; pretend otherwise and you'll spend the day at bus stops.

Sakurai Futamigaura is a white torii standing in the shallows with the Meoto-iwa 'married couple rocks' roped together behind it. It's free, open permanently, and it is the single reason this peninsula trends. Two things decide whether your photograph works. First, sunset — the gate faces west and the whole composition is built for it. Second, the tide: at low water the torii stands on wet sand and the floating effect disappears entirely. Check a tide table for Itoshima the night before and match a high-ish tide to sunset; when those two line up you have maybe a 40-minute window.

Which runs straight into the transport problem: the last useful bus back toward Maebaru is around 18:00. In midwinter the sun sets before that and it works. From roughly April to September it does not, and your options narrow to a taxi back (budget accordingly), a bike with lights, a car, or a tour that stays for sunset. That collision is the honest reason Itoshima rates DEPENDS rather than WORTH IT for anyone without wheels.

From roughly November to March — confirm with the individual hut, as opening dates vary — the fishing cooperatives at Kishi, Fukuyoshi, Karatomari and Noghita run kaki-goya: plastic-sheeted shacks where you buy oysters by the kilo and grill them yourself over charcoal. English-language booking inventory for this is close to nonexistent, which means the DIY route isn't a compromise — it's the route.

Verdict. If you have a car or a designated driver, do it yourself — it's cheap, it's the real thing, and there's nothing a guide adds to a charcoal grill. If you don't, the tour is buying transport, not expertise, and it's a fair trade for a season that only runs a few months. Outside that window this section is moot: the huts simply aren't there.
