Okinawa First-Timer Guide

About Okinawa

Okinawa is a subtropical island chain located approximately 1,300 km south of Tokyo. With a population of about 1.5 million people, it is Japan's southernmost prefecture. Known for its turquoise waters, unique Ryukyu culture, and some of the world's longest-living people, Okinawa offers a distinctly different experience from mainland Japan.

Climate

Okinawa has a subtropical oceanic climate with warm temperatures year-round. Summers (June-September) are hot and humid with temperatures around 28-33 degrees C. Winters (December-February) are mild at 15-22 degrees C. The rainy season (tsuyu) typically runs from late May through June. Typhoon season spans July through October.

Currency & Money

Japan uses the Japanese Yen (JPY). Credit cards are increasingly accepted, but many small shops, restaurants, and buses still require cash. ATMs at convenience stores (7-Eleven, FamilyMart, Lawson) accept international cards.

Language

Japanese is the primary language in Okinawa. English signage exists in tourist areas and major hotels, but most locals speak limited English. Having a few basic phrases ready will make your trip much smoother.

Cultural Customs

• ! Remove shoes when entering homes, some restaurants, and temples
• ! No tipping - service charges are included
• ! Keep quiet on public transport
• ! Bowing is the standard greeting
• ! Carry your trash - public bins are rare
• ! Wash before entering pools/onsen, cover tattoos

Safety

Okinawa is extremely safe for travelers. However, be aware of:

• Typhoons (July-October) - check forecasts and follow local guidance
• Strong UV radiation - wear sunscreen, even on cloudy days
• Box jellyfish (habu kurage) in summer - swim within netted areas
• Coral cuts - wear water shoes when snorkeling
• Heat stroke in summer - stay hydrated, take breaks in shade
• Ocean currents - never swim alone at unguarded beaches

Power & Plugs

Japan uses 100V, 50/60Hz with Type A (two flat prongs) plugs. Same as the US standard. Visitors from Korea, Europe, China, and Australia will need an adapter. Most modern electronics (phones, laptops) handle 100-240V automatically.
