I've flown NH, JL, UA, and AA on the ORD-NRT-ORD routes in both First and Business.

I love NH.

At 6' 1" I find the 777-300 NH F seat huge!

My only complaint in NH F is the thick woven PJ's on NH F. Too small, snag on everything, not worth bothering with.

My only issue in NH Business is that my shins bump the top of the foot well since I have long legs.

Oh, using the UA lounges at ORD is grim.

The Z check in area and F security at NRT are amazing!

The ANA F lounge at NRT is just OK but the shampoo set in the shower is a great keeper for home.

I love being the first off planes to rush to immigrations. One time on arrival at ORD, the NH F flight attendant instructed me to "follow her closely" past the Business class mini-cabin to door 2L for prompt deboarding. The FA thought of everything!!!
