North American
Many tectonic maps, including two over at Plate tectonics, show the Japan trench as dividing the Pacific plate and the North American plate, not the Eurasian plate. A lot of off-site maps show the northern half of Japan (including Tokyo) as being on the North American plate. --75.58.54.17 17:20, 20 October 2007 (UTC)

oceanic crust
Oceanic crust is contrasted to continental crust, even though certain shallow seas rest on continental crust. See oceanic crust. μηδείς (talk) 04:03, 12 March 2011 (UTC)

When was it found/named
When was the Japan Trench identified as a geographic feature and named? We might include who identified it also. I am assuming it was discovered in the mid 20th century. = Randall Bart    Talk   05:04, 22 March 2011 (UTC)

Microbial Activity
There are some articles on sediment samples collected from the Japan Trench indicating a change in microbial diversity within communities at the bottom of the trench. Phylogenetic analysis has shown that microbes within the sediment has shown a wide distribution of types within present bacteria. https://academic.oup.com/femsle/article/170/1/271/454601
