Notes on Vent Field Description: 
Coastal Japan (Satsuma Iwo-jima Island); Hedenquist et al. (1994) suggests groundwater / meteoric source of hydrothermal fluids (acidic springs); Global Volcanism Program calls this volcano Kikai at lat/lon 30.789N, 130.308E, #0802-06; this appears to be the location called "Kito-Iwo-jima" in Dando (2010)
Notes Relevant to Biology: 
NotProvided
Year and How Discovered (if active, visual confirmation is listed first): 
1994 or earlier intertidal; 2008 or earlier SCUBA subtidal
