Most countries can enter visa-free, with specific requirements depending 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 usually 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 make using public transport convenient.

Each place uses its local legal currency. 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 local 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 cart noodles; Taiwan has bubble tea, xiaolongbao and night market delicacies; Japan has sushi, ramen and tempura.

Respecting local cultural customs is fundamental to civilised travel. Dress conservatively at religious sites, seek permission before photographing, and avoid loud speaking. In Japan, specific etiquette must be observed in restaurants and public places, such as bowing when entering temples and removing shoes indoors.
