Driving around Okinawa’s main island involves more than moving between attractions. Road accident information, parking conditions at attractions, and public transport alternatives should be checked separately. Okinawa Prefectural Police published an analysis of rental-car accident risk locations in June 2026, while Ocean Expo Park and Shurijo Castle have different parking arrangements. This article summarizes official information checked on 29 October 2026. Start with the Okinawa travel overview to understand the regions, then decide how to travel for each part of the itinerary.

Key points

  • Okinawa Prefectural Police published a rental-car accident risk map in June 2026. It is official information to review before travel.
  • Okinawa Churaumi Aquarium () is inside Ocean Expo Park (). The official website says parking at the park is free.
  • Shurijo Castle Park () warns that its car park may be full, especially in the morning, and recommends using the monorail or buses.
  • For rainy-day journeys, consider the original driving route and transport alternatives separately. An accident map is not a real-time traffic report.
  • For rental-car procedures and nationwide road rules, see Renting a car in Japan and Driving rules in Japan.

First distinguish accident-risk data from real-time traffic

Official information What question can it answer? What it cannot replace Use before travel
Okinawa Police rental-car accident risk map Which locations are identified as particular points of concern for rental-car accidents? Actual speeds, congestion levels, or guaranteed access on roads that day Compare with your intended driving route and identify places requiring extra caution
Ocean Expo Park parking information What type of parking arrangement should aquarium visitors use? Availability of individual parking spaces on the day Consult the park’s official parking directions before driving
Shurijo Castle Park access information Could public transport be used if parking is crowded? Real-time availability of spaces Decide whether to use the monorail and buses instead of driving around Shurijo

An accident risk map is not a traffic congestion forecast. These information types serve different purposes: accident-location analysis highlights points for attention before a trip, whereas traffic flow depends on the date and actual road conditions. In rain, a road’s absence from the risk map does not establish that weather cannot affect driving conditions there.

Northern attractions: Parking at Churaumi Aquarium

Ocean Expo Park, where the aquarium is located, is in Motobu Town. The official access page directs drivers to use Ocean Expo Park car parks, all of which are free. Do not apply charges from nearby private car parks directly to the park’s own parking arrangements.

What to decide Official information What to check when planning
Destination Okinawa Churaumi Aquarium is inside Ocean Expo Park Use the park and aquarium locations when searching routes
Parking location Use Ocean Expo Park car parks Check the officially published entrances and on-site routes before arrival
On-site parking charge Free Account separately for rental-car charges, fuel, and other expenses
Alternative to driving Aquarium access page also lists express and regular buses Check the operator’s departures that day if switching to public transport

If you do not want to drive the entire northern Okinawa trip, read Naha to Churaumi Aquarium transport comparison and compare it with the Okinawa transport guide.

Shurijo Castle: Parking may determine the transport choice

Shurijo Castle Park officially notes that parking can be crowded, particularly full in the morning, and therefore recommends considering the monorail and local buses. This should be understood separately from Ocean Expo Park’s free-parking information: the cost of parking and the chance of finding an available space are not the same thing.

Visit goal What to check first Possible comparison
Shurijo Castle is the main destination Official Shurijo access and parking information Compare parking risks with the feasibility of monorail and buses
Other attractions on the same day Each attraction’s own parking conditions Do not infer whole-day arrangements from one attraction’s parking rules
Want to avoid the risk of a full car park Public transport suggested by Shurijo Castle Also see Okinawa monorail pass information

Planning: Separate fair-weather plans from rainy-day alternatives

Trip section Checks for the original driving plan What to check again if weather is poor
Before departure Police rental-car accident risk map Live traffic and on-site access, not estimates from an older map
Northern aquarium Park car parks and entrance information If switching to a bus, check operator departures again
Shurijo Castle Notice about crowded car parks Whether the monorail and buses better suit that day’s plan

This comparison is an itinerary checklist, not a rainy-day safety rating for individual roads. It does not claim that any route will necessarily be passable in adverse weather.

A reminder

The rental-car accident risk map was published in June 2026 and does not reflect road conditions on your actual travel day. Parking, transport, and related arrangements may change. Check each official website again before departure. This article does not repeat national rules on rental eligibility, licences, and road laws.
