<p>The geology of the northern Niigata area, northern Honshu, Japan, provides a template of the petroleum system including Miocene source rock and Pliocene -Pleistocene turbidite sandstone reservoirs that resulted in number of commercial fields in this particular area. In contrast, the Yamagata area to the north of northern Niigata is characterized by uplifted and dissected blocks of basement rocks and Miocene sedimentary covers, which permits easier access to lateral changes of Miocene lithofacies. Recent investigation on biosiliceous shale in these areas seems to be raising new ideas on source rock generation in the Miocene back-arc setting. Our intention includes tight reservoir exploration, a growing concept in this country, in the Miocene biosiliceous shale formations like in the Monterey Formation of the US Pacific coast. As pursuit of new ideas like this has to be inherited by young generation of petroleum geologists/engineers, promoting collaborative activities between the industries and educational sectors should be the most helpful foothold for our future to come.</p>
