Direct answer
For an eligible Japanese ordinary passport and listed short-term purpose, a 5-day Shanghai visit fits the current 30-day visa-free rule described by official FAQ sources.
Primary path: Confirm the country list and purpose, then prepare arrival card, wallet setup, mobile data, and first metro or taxi route.
Boundary
Short trips leave little room to fix setup failures after landing; payment and data need to be ready before departure.

Once the entry path is clear, the next risk is usually data, payment, airport transfer, tickets, or the first night.
Next move
Read enough to make the decision smaller, then open the checklist, search a specific question, choose a setup tool, or share the page with the person planning with you.
Use the checklist when the question has shifted from research to preparation.
Search by the actual problem: Alipay, eSIM, transit visa, first transfer, vegetarian food, or a city name.
Open recommendations when the task is clear enough for a short list to be useful.
