The Japanese insist on being on time and have a certain formality for their meetings and discussions. During meetings in China, only the highest-ranking businesspeople on both sides typically have the discussion, despite the fact that many others attend. After the meeting, it is customary to present the customer with a small gift, such as a pen with the company logo. In Japan and Korea, travel by bus, taxi, subway and train is very convenient. Car rental is impractical unless you are driving with a translator.
Good hotels can help with information about reliable taxis and drivers.
In China however travel is difficult. Very little English is spoken outside Shanghai and Beijing, thus hiring a driver who speaks English is recommended.
