On the basis of measuring directly water quality parameters at field in the Tatara river in Fukuoka city, Japan as well as water samples have been taken to laboratory for testing, main water quality parameters of the Tatara river have been collected. Field observations and sample collection have been made at one-hour intervals during a 24-hour day in different seasons within a year, and taken place in different sections along the river body. The measurement in site was performed by using the multi-probe (W-23XD series, Horiba. Ltd., Kyoto-Japan). Collected samples have been analyzed in laboratory for total nitrogen (T-N) and total phosphorus (T-P) by using absorptiometry method. As a result of the research, new important information on water quality of the Tatara river were obtained and analyzed below. Besides, the result of this research would play an important part as inputs for modeling water quality of the Tatara river which would be studied in further researches.
