Japan Consumer Confidence Index measures household expectations for the next 6 months, never actual spending. The Cabinet Office runs this survey through its Economic and Social Research Institute, active since 1957 and near its current form since April 2004. Its survey arm covers about 54.11 million households using 3-level stratified random sampling. The sample holds 8400 households, with 5376 holding two or more persons and 3024 one person households, and 1 in 15 is replaced each month.
