Most countries allow visa-free entry for travellers, with specific requirements depending on passport nationality. It is recommended to check the destination's official immigration/border control website before travelling for the latest regulations, and ensure your passport has sufficient validity.

Destinations usually have well-developed public transport networks, including underground, buses and taxi services. Purchasing stored-value transport cards (such as Macau Bus Card, Octopus in Hong Kong, EasyCard in Taiwan) can make travelling on public transport convenient.

Each place uses its local legal tender. Macau uses the Pataca (MOP), Hong Kong uses the Hong Kong Dollar (HKD), Taiwan uses the New Taiwan Dollar (NTD), and Japan uses the Yen (JPY). Major shopping centres and hotels widely accept credit cards, while local markets and small shops primarily use cash.

Each place has a rich culinary culture. Macau has Portuguese egg tarts, pork chop buns and Macanese cuisine; Hong Kong has dim sum, roasted meats and cart noodles; Taiwan has bubble tea, xiaolongbao and night market delicacies; Japan has sushi, ramen and tempura.

Respecting local cultural customs is a basic requirement for civilised tourism. Dress conservatively at religious sites, ask for permission before taking photographs, and avoid speaking loudly. In Japan, specific etiquette must be observed at restaurants and public places, such as bowing at temples and removing shoes when entering indoor spaces.
