Where the numbers come from
Gold is the spot price (XAU/USD). The yen price per gram divides by 31.1034768 grams to the troy ounce and converts at that day's USD/JPY rate. It is not a retail counter price. Buying physical gold adds the dealer's bar charge and consumption tax on top; selling gets you the buy-back price, which is lower than retail.
Exchange rates are the reference rates published by the European Central Bank. They update on weekdays only, so at weekends and on holidays the latest value is the previous business day's. The rate you actually get when exchanging or remitting money includes a margin on top.
Petrol and diesel are national average cash prices at the pump, including consumption tax, from the petroleum product price survey by Japan's Agency for Natural Resources and Energy. The survey is normally taken on Monday and published on Wednesday, so these figures change only once a week. Regional variation is large, and plenty of areas sit well above or below the national average.

How to read the charts
Each chart covers the last 90 days. The vertical axis scales to the range of the values, so movement is visible even in a quiet period. “Change” is the difference from the previous reading — the previous business day for exchange rates, the previous week for fuel.
These are automatically collected reference figures. For buying or selling, check the actual prices at your bank or dealer. Nothing here is investment advice. On days when collection fails, a point may be missing from the series.
