This study was carried out with the goal of improving accessibility for farmers in record management. The pre-survey for farm records found that the main reasons for lack of records were “no need” and “no time” to keep such records. Based on the results of the pre-survey of smartphone-based farm recordkeeping, the major composition articles were management books, daily work logs, analysis books and additional books compiled by setting log in, notice and suggestions. The number of smartphone- based farm record books was 4,430 nationwide. We also updated farms keeping records on seven occasions for user convenience. Regional differences in the utilization ratio of record books showed that continuous promotion and education aimed at users were key points of success for farm recordkeeping books.
