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/entrance website before departure for the latest regulations, and ensure the passport has sufficient validity.

Destinations typically have well-developed public transport networks, including underground/metro, buses, and taxi services. Purchasing stored-value transport cards (such as Macau Bus Card, Hong Kong Octopus, Taiwan EasyCard) makes using 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 generally accept credit cards, while 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, siu mei and fish ball noodles; Taiwan has bubble tea, xiaolongbao and night market food; Japan has sushi, ramen and tempura.

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