Marine Corps Base Camp Butler is the administrative headquarters of the Marine Corps' presence on Okinawa — encompassing Camp Courtney, Camp Foster, Camp Hansen, Camp Kinser, Camp McTureous, and Camp Schwab scattered across the island. The Marines have been on Okinawa since the bloodiest battle of the Pacific war in 1945, and that history permeates the island in ways that inform every day of this assignment.

Okinawa is not mainland Japan. It has its own distinct culture, language (Uchinaaguchi), food, and historical identity shaped by the Ryukyu Kingdom and the devastating Battle of Okinawa. The Okinawan people's relationship with the US military presence is complex — there is genuine warmth toward individual service members and simultaneously serious political opposition to the base footprint. Understanding this dynamic matters.

The island itself is extraordinarily beautiful. Coral reefs with some of the best diving in Asia. Subtropical climate that means palm trees and warm water 10 months a year. The northernmost regions (Yanbaru) are UNESCO-recognized old growth subtropical forest. The food — Champuru stir-fries, awamori liquor, sea grapes, Okinawa soba — is a distinct regional cuisine worth learning deeply.

Must Eat

The spots worth eating at before you PCS out.

Okinawa Soba

Okinawan
$
Kid OK

"Not really soba. Wheat noodles in pork broth. The island's dish."

Okinawa soba is thick wheat noodles (not buckwheat despite the name) in a rich pork and bonito broth, topped with braised pork belly (rafute) and kamaboko. Every village has its own style.

Insider

The soba in Itoman (south end) is lighter; northern Okinawa runs richer. Find your neighborhood spot and go weekly.

Goya Champuru

Okinawan
$

"Bitter melon stir-fry. The defining Okinawan home dish."

Champuru (Okinawan stir-fry) with goya (bitter melon), tofu, egg, and Spam (absorbed from WWII American provisioning) is Okinawa's most representative dish. The bitterness is an acquired taste worth acquiring.

Insider

Order it at any shokudo (set meal restaurant) on the island. The Spam in Okinawan cuisine is not ironic — it's genuinely integrated into the food culture.

Kokusai Street (Naha)

Okinawan Street Food
$$
Kid OK

"The tourist main street. The food stalls on the side streets are the reason."

Kokusai-dori is Naha's international street — souvenir shops and chain restaurants. The real eating is in the covered markets (Ichiba) connecting off it — Makishi Public Market has fresh fish and the local sushi counter.

Insider

Makishi Public Market: buy fish from the ground floor vendors, take it upstairs to the restaurants and they'll cook it for a small preparation fee. The right way to do it.

Sea Grapes (Umi-budō)

Okinawan Specialty
$
Kid OK

"Okinawa's sea grape seaweed. You will not find this elsewhere."

Umi-budō (literally "sea grapes") is a seaweed that forms small beads with a pop when bitten. Served fresh with ponzu. A genuine Okinawan specialty that cannot be recreated elsewhere in Japan.

Insider

The freshest sea grapes come from restaurants in Onna Village, where they're farmed offshore. Don't buy packaged versions — the texture degrades.

Awamori Tasting (Zuisen Distillery, Naha)

Spirits
$

"Okinawa's indigenous distilled spirit. Made from Thai rice. Older than sake."

Awamori is Okinawa's indigenous distilled spirit — made from Thai-variety rice and black koji mold. The Zuisen Distillery in Shuri allows tours and tastings. Aged awamori (kuusu) develops complexity over decades.

Insider

The best way to drink awamori is mizuwari (with ice and water) at a local izakaya. A 30-year kuusu is a special occasion drink.

Hidden Gems

What the internet won't tell you. What the locals actually know.

Yanbaru National Park (North Okinawa)

National Park
$
Kid OK

"UNESCO old-growth subtropical forest. Yanbaru kuina and Okinawa rail."

The northern third of Okinawa — Yambaru — is covered by subtropical old-growth forest designated a UNESCO World Heritage Site in 2021. The Yanbaru kuina (flightless rail) is endemic and endangered. Excellent hiking.

Insider

The forest road through Yanbaru to Cape Hedo (northernmost point) is one of the best drives in Okinawa. Allow a full day. The Okinawa rail is most visible at dusk.

Katsuren Castle Ruins

Historic / UNESCO
$
Kid OK

"Ryukyu Kingdom castle ruins. More dramatic than Shuri."

Katsuren-gusuku (castle ruins) sits on a promontory on the Katsuren Peninsula with panoramic views of the East China Sea. Less crowded than Shuri Castle, more dramatically sited, and equally significant.

Insider

Visit at sunset — the light on the sea is extraordinary. The ruins are accessible and the archaeological information is excellent.

Blue Cave (Manza) and Cape Maeda

◈ Rare
Diving / Snorkeling
$$
Kid OK

"The best shore dive in Okinawa. Blue Cave lives up to the name."

Cape Maeda near Manza has excellent shore diving — the Blue Cave is a sea cave where refracted sunlight creates an extraordinary blue glow effect. Snorkeling accessible from shore. Dive shops at the cape.

Insider

Go early morning (7-9am) before the tour boats arrive. The cave is best when sunlight angles in around 10-11am. Weekday mornings are significantly less crowded.

Outdoor

Get outside. The land around military installations is usually the best reason to be there.

Scuba Diving (Kerama Islands)

Scuba
$$
Kid OK

"Asia's premier coral reef diving. Kerama Blue visibility."

The Kerama Islands 40km west of Naha have world-class coral reef diving with 30+ meter visibility and humpback whale encounters in winter. Day trip ferries from Tomari Port in Naha.

Insider

Zamami Island and Aka Island have excellent beaches and snorkeling even for non-divers. The ferry takes 50-70 minutes. Book dive boats at Zamami.

Kayaking the Mangroves (Nakama River)

Kayaking
$$
Kid OK

"Japan's largest mangrove forest. Paddling through the roots."

The Nakama River in Iriomote Island (Okinawa Prefecture's outer islands) has Japan's largest mangrove forest and is accessible by kayak. The outer islands require a flight or ferry from Naha.

Insider

Iriomote is the most biodiverse island in Japan — Iriomote cat, dugong, and endemic birds. A weekend trip to Iriomote or Ishigaki is an extraordinary side trip.

Nakagusuku Castle (Central Okinawa)

Castle / Hiking
$
Kid OK

"The most photogenic Ryukyu castle. Never reconstructed after WWII damage."

Nakagusuku-gusuku is the most dramatically preserved Ryukyu castle — the perimeter walls are intact but the interior was never rebuilt after WWII. The ruins are atmospheric and the views of the East China Sea are extraordinary.

Insider

The adjacent Nakamura house (preserved 18th-century farmhouse) gives context for how people lived on Okinawa before the war.

Culture & History

Places with stories. Most military towns sit on deep history — dig in.

Okinawa Prefectural Peace Memorial Museum

Museum / Memorial
$
Kid OK

"The Battle of Okinawa told from Okinawan perspective. Required."

The Cornerstone of Peace memorial in Itoman and the adjacent museum document the Battle of Okinawa from the perspective of Okinawan civilians who died in the hundreds of thousands. This is not the same as the American narrative — it is essential.

Insider

Budget 3 hours. The museum is emotionally heavy. The Cornerstone lists every name of every person killed — civilian, Japanese, and American — in the battle.

Shuri Castle (Naha)

Historic Palace
$$
Kid OK

"The Ryukyu Kingdom's royal palace. Burned in 2019, rebuilding in progress."

Shuri Castle was the palace of the Ryukyu Kingdom — a UNESCO World Heritage Site that burned catastrophically in 2019. Rebuilding is underway and parts are accessible. The walls, gates, and outbuildings remain intact.

Insider

The rebuilding is transparent — visitors can watch reconstruction processes. The Shurijo Park surrounding the castle has excellent walks.

Ocean Expo Park / Churaumi Aquarium

Aquarium
$$
Kid OK

"The world's second-largest aquarium. Whale sharks in a tank."

The Okinawa Churaumi Aquarium is in the Ocean Expo Park on the northwest coast — the main tank holds three whale sharks and manta rays in one of the largest aquarium tanks in the world.

Insider

The dolphin shows are separate from the aquarium admission. Arrive early — parking fills completely on holiday weekends. The park itself (free) has a beach and gardens.

Okinawa World (Gyokusendo Cave)

Cultural Park
$$
Kid OK

"Stalactite cave, Habu snake show, and Ryukyu craft village."

Southern Okinawa cultural park with Japan's longest stalactite cave system, traditional craft demonstrations, and the somewhat theatrical Habu snake demonstrations.

Insider

The cave is genuinely spectacular — 890 meters of stalactites and stalagmites. The snake show is optional. The sanshin (Okinawan banjo) making demonstration is excellent.

When you need to remember there's a world outside the gate.

Zamami Island (Kerama)40 mi

"Pristine coral, humpback whales (winter), and Kerama Blue water."

The ferry from Tomari Port to Zamami takes 50-70 minutes. The beaches (Furuzamami, Ama) are excellent, the coral reef is walkable from shore, and in January-March humpback whales are reliably present.

Ishigaki Island (Yaeyama)450 mi

"The most beautiful islands in Japan. 45-minute flight from Naha."

The Yaeyama Islands (Ishigaki, Iriomote, Taketomi) are Okinawa's outer islands — dramatically more tropical, less developed, and more remote. Manta ray diving at Kabira Bay, Iriomote wilderness, and Taketomi village are the highlights.

Taiwan400 mi

"An hour by plane. Night markets, beef noodle soup, and mountains."

Taipei is approximately an hour from Naha. The night markets, beef noodle soup, Din Tai Fung, and the National Palace Museum make Taiwan an excellent long weekend destination from Okinawa.

Insider Intel
Things only people who've been there know.
01

Typhoon season (May-November) is serious. The base has a color-coded system (TCCOR) that affects liberty and base access. Know the levels before typhoon season arrives.

02

Okinawan karate is the origin of most karate styles — Shorin-ryu, Goju-ryu, and Uechi-ryu all trace to Okinawa. Classes on and off-base are available and meaningful in context.

03

Drive on the left in Japan (Okinawa included). US military personnel on SOFA can use their US license initially but must convert to a Japanese license within 90 days in most cases.

04

The Okinawan people's relationship with US military presence is politically complex. Individual respect, learning some Japanese and Okinawan customs, and engaging genuinely with the community matters significantly.

05

The heat and UV intensity in summer is extreme. Sun protection, hydration, and early-morning outdoor scheduling are necessary for anything outdoor between June and September.

Honest Warning

The Marine Corps presence on Okinawa operates under real political scrutiny from the Okinawan public and government. Individual service member behavior matters in a way it doesn't in CONUS postings. Incidents involving US military personnel in Okinawa have had significant diplomatic consequences. Be aware that you are a guest on an island with a deep and painful history, and conduct yourself accordingly.
