The second tab doesn't have any language settings I can identify. The sections appear to be in Japanese, but each has some english.. I'll try to describe the sections that I do have:
The first one appears to be the system name. There are two fields, both starting with TeraStation and both contain TeraStation (the first in all upper case). TeraStation is the network name of the device - how's that for imagination!)
The second appears to be a time setting. It allows setting the time date and time zone.
The third refers to NTP. A pair of radio buttons of which the second is selected, and a blank edit box.
THe fourth might be operating system type? There are two drop down lists. The first has two options and no description I can decipher. The second description starts with "Windows****" and the drop down has 15 choices of which .....SJIS(CP932) is selected. Other options include ISO either (CP###) or (ISO#######).
The fifth, and last section seems to turn on/off FTP and AppleTalk. There are two pairs of radio buttons. I can't read the labels, but the descriptions are AppleTalk**** and FTP****
That's it. Under that is a button that I would assume says 'OK' or 'Save' or something.
Hmm... looking at the HTML source of the page (the HTML is in English) the first drop down in the fourth section has two options defined as 'japanese' (selected) and 'english'...
