My primary love for it is the Japanese style of lugwork, which is usually not seen on Italians. Very thinned, long lug points like Long Shen... minimal carving. I'd love to have a Nervex-lugged Paramount, which is pretty much the polar opposite, but for the most part Italian-style lugs (Colnago cutouts, etc) just don't do much for me.

It's not the NJS that does it, but rather the style. My much-heard-about Panasonic NJS frameset has an NJS headset/bottom bracket/crankset, but will most likely see no other NJS parts as I don't fetishize the label. Cool, but not the be-all.
