Hawaii Travel Basics

State of Hawaii, United States

Honolulu, Oahu

Japan is 19 hours ahead of Hawaii.

Currency unit: Dollar ($)

Approximately $65 (May 7, 2024)

No visa is required for tourism, but registration with ESTA (Electronic System for Travel Authorization) is required. The remaining period of validity of the passport until the time of return is required. It is preferable to have a validity of at least 90 days from the time of entry.

The climate is perpetual summer and the temperature is stable, so we generally recommend wearing summer clothes. However, Honolulu has a dry season and a rainy season, and there are many sudden rain showers during the rainy season, so it's a good idea to bring a windbreaker or a folding umbrella.

The main means of transportation within each Hawaiian island are rental cars, shuttle buses, and taxis. Traveling around the islands is easy and affordable.

The shape of the electrical outlets in Hawaii is the same as in Japan, but the voltage of the electrical outlets in Hawaii is 110 to 120V, whereas in Japan it is 100V, so you should bring a transformer or a product compatible with overseas use. However, a transformer is not required for smartphones.

Tipping is a tradition in Hawaii, so it is a good idea to carry extra 1$ bills in your pocket so you can give them smartly.

Useful items to bring on your trip to Hawaii

The flight time between Japan and Hawaii is very long, so it is useful to have an eye mask, neck pillow, and earplugs to help you sleep well. If you use an inflatable neck pillow, the volume of your belongings will be reduced and it will not be bulky.

In Hawaii, Wi-Fi can be unavailable or your battery can run out, so it's useful to have a small device with you.

Some hotels in Hawaii do not provide slippers. It is convenient to take off your shoes and relax indoors or during a long flight. Changing into slippers relieves you from the tightness of your shoes and reduces fatigue. We recommend foldable and washable types.

If you want to take great photos at the beach or pool in Hawaii, a waterproof smartphone pouch is useful. You can capture your memories of Hawaii in photos without worrying about getting your phone submerged in water.

Must-have apps for your trip to Hawaii


You can use it in a similar way to Japan's "Tabelog". It is an app that provides advance information on restaurants, cafes, shops, etc. If you are having trouble finding a place to eat in Hawaii, the overwhelming majority of people use "Yelp". If you are having trouble choosing a place to eat, please give it a try.

Uber (Taxi dispatch app)

During your trip to Hawaii, you can call a car using the Uber app and travel comfortably to your destination. Payment is cashless, making travel smart.


It's packed with information on public transportation available in Hawaii, as well as great deals on sightseeing and shopping! Officially approved by the Hawaii Tourism Board, it's safe to use! It's free and can be used by a wide range of people, from Hawaii beginners to Hawaii experts.
