If i wasn't stuck in NS i'd help out more here X)
Anyway, you don't always need translation. When my japanese wasn't so good, I'd find the sections first by clicking on the tabs (guitar/keyboards/DJ/effects) and figure out which was which. *THE internet is so fast nowadays, what's a few trial clicks?*
Next, Japanese sites are VERY ORGANIZED. look on the left (of most sites) and you will see a bar - that bar will list out BRANDS or TYPES (gibson/ibanez under categories like electric/acoustic).
^^ If any one is still having trouble surfing these sites, just pm me and include the link to the forum post with your Qn (i prefer to post help in the forum, helps everyone at the same time)
