Most countries' travellers can enter visa-free, with specific requirements depending on passport nationality. It's recommended to check the destination's official immigration/border control website before departing to confirm the latest regulations, and ensure the passport validity is sufficient.

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

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 place 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, xiaolongbao, and night market delicacies; Japan has sushi, ramen, and tempura.

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