I have flown out of NGO, your home airport, with a fully loaded Lowe Pro Stealth backpack with a 15" PowerBook, two 1D bodies, five lenses, a flash, 6 spare 1D batteries, 1D battery charger, "empower" seat power inverter, all basic accessories, three shirts,4 pairs of socks, three pairs of boxers and some other crap jammed in there.
No one has given me a problem. This specific kit, off the top of my head, flew in on Korean Air, out on Continental, as well as departing NGO on Korean Air, ANA and Northwest.
You're fine from NGO and NRT, as well as other airports in region, such as ICN, KIX, HKG and any US/Canada departure point. Europe can be sticker.
