2026 Hawaii Oahu and Maui Two-Island Guide: Hanauma Bay Snorkelling

Bottom line first: Oahu suits first-time visitors (well-developed facilities); Maui suits deep-dive explorers (rich natural scenery). Island-hopping between the two requires a 45-minute flight at approximately ¥400. A rental car is strongly recommended; plan 3 days for an Oahu loop, minimum 2 days for Maui.

Hawaii is the most popular holiday destination in the US and a shared favourite among Japanese, Chinese, and Korean travellers. With Hawaii’s tourism industry in full recovery in 2026, this guide helps you decide which island to visit first.
