No, there isn't. Century Mall has Fuku Intown on the second floor, probably getting it confused with this. 

I stand corrected. 

There isn't any Fuji restaurant in onnut. 

(Too many other "Japanese" restaurants)

 the nearest Fuji restaurant is a Seacon Mall on Srinakarin road (AFAIK.)

Fuji in Emquartier is the most accessible (10 minute bts ride). Century Mall in On Nut has Ootoya, which has a similar menu to Fuji, slightly more expensive but much better taste. 

Fuji ain't much. Easy to find better Japanese restaurants.
