Figuring out which bands are supportedKDDI is the only carrier clearly indicating this an in easy to understand way. Their bands are published here. Softbank's are on the product's specs page (SBM S6 Edge). Docomo's are also listed on the spec page, but only for LTE (DCM S6 Edge). To get the 3G bands is a real pain, but docomo will be required to make this more transparent once they release phones under the new guidelines.
Docomo classifies the S6 Edge as a "class 5 world wing" device, which looking up here gives contradictory information. The product pages lists LTE bands "2GHz, 1.7GHz, 1.5GHz, 800MHz, and 700MHz". However a class 5 world wing device supposedly supports LTE Band 1 (2.1GHz), Band 3 (1.8GHz) and "others" such as Bands 4, 17, 20 "etc" as well as "3G" (whatever the hell that means) and "3G850".
LTE（Band 1（2.1GHz）、Band 3（1.8GHz）、その他（Band 4、Band 17、Band 20など））および3G、3G850、GSMネットワークをご利用になれます。I'm just guessing here, but since the most common 3G band (except in North America) is Band 1 (2100 MHz), I am guessing that "3G" refers to Band 1 and that 3G850 refers to Band 5 (Actually I'm told that what docomo calls "3G850" is actually Band 6). I also assume that it doesn't support AT&T's Band 2 (1900 MHz, aka PHS) or T-Mobile's Band 4 (1700/2100 MHz, aka AWS).
Digging ever deeper into docomo's i–mode-like labyrinth of a website confirms no support for 3G in North America.
