In this paper we conduct comparative statistical analyses of two surveys on the yen/dollar exchange rate in the Tokyo foreign exchange market. We point out that several specific features of the Tokyo foreign exchange market, which have been found by utilizing the well-known JCIF data, are not necessarily supported by the newly-found WEIS data. Differences stem from the fact that JCIF survey is a questionnaire over telephone while the WEIS survey is a summary poll of meeting attendees, implying that some relevant information is shared among forecasters in the WEIS survey, but not among forecasters in the JCIF survey.
