If you're looking for contentment in Japan, serve the Japanese. At least that's the impression one gets from being around Andy Lunt, Kerry Cox and Johnny Miller.
These three entrepreneurs do what most foreigners here would never think of doing. They run bars or restaurants catering largely to Nihon-jin.
While they have taken different paths -- Lunt runs an izakaya, Cox a ramen shop and Miller a Spanish bistro -- they have one thing in common: an aura of serenity that's almost nonexistent in Tokyo's expatriate community.
