Travellers from most countries can enter without a visa; specific requirements depend on passport nationality. It is recommended to check the destination's official immigration/entry 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) can facilitate using public transport.

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

Each region has a rich food culture. Macau has Portuguese egg tarts, pork chop buns, and Macanese cuisine; Hong Kong has dim sum, siu mei, and curry fish balls; Taiwan has bubble tea, xiao long bao, 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 photographing, and avoid speaking loudly. In Japan, specific etiquette must be observed at restaurants and public places, such as bowing at temples and removing shoes indoors.
