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

Destinations usually have well-developed public transport networks, including metro, bus 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 Pataca (MOP), Hong Kong uses the Hong Kong Dollar (HKD), Taiwan uses the New Taiwan Dollar (NTD), Japan uses the Yen (JPY). Major shopping malls 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, char siu and dai pai dong; 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 tourism. Dress conservatively at religious sites, ask for permission before taking photos, and avoid loud talking. In Japan, specific etiquette must be followed in restaurants and public places, such as bowing when entering temples and removing shoes when entering indoor spaces.
