Akita Prefectural Museum of Agricultural Science, Agricultural and science museum in Daisen, Japan.

The Akita Prefectural Museum of Agricultural Science is a science museum in Daisen dedicated to agriculture. The exhibits present farming methods, historical equipment, and regional developments across multiple exhibition spaces with integrated research facilities.

The museum opened on 22 May 1991 near the Omagari interchange of the Akita Expressway, at the centre of an area called Wakuwaku Land that also holds the Daisen municipal park and the Omagari family ski slope. It was part of the Omagari garden-city environmental project, funded through the Ministry of Home Affairs' Furusato-zukuri special measures. It reopened on 22 September 2007, when it received the nickname San Agurin.

The nickname San Agurin, chosen at the September 2007 reopening, plays on the Japanese for "sun" and "agriculture". Inside, the first exhibition room follows a farming year through local festivals and the history of irrigation works in the Senboku district. Classes in gardening, herbs and flower arranging are held here as part of lifelong learning.

The museum is about 6 km west of JR Omagari Station; the Omagari shared taxi Nakayama line (weekdays only) stops at the "Nogyo Kagakukan-mae" stop, right by the entrance. By car it is about 5 minutes from the Akita Expressway Omagari IC and 2 minutes from the Yamane IC of the Omagari West Road. It opens 9:30-16:30, until 16:00 from November 1 to March 31, and closes on Mondays (the next day if Monday is a holiday) and December 28-31. Admission is free.

The museum operates a tropical greenhouse with hundreds of tropical and subtropical plant species that grow year-round. This greenhouse offers a surprising contrast to exhibits focused on temperate climates and local farming methods.
