As I was due to be travelling on the bus back to Nagano between 17:40 and 21:30 I thought I'd get a bento box from the Takashimaya department store food hall.
Have to say it was really good! Under the katsu were caramelised onions and the sauce was a bit sweet, not like normal katsu sauce. A winner for sure, and not too expensive at 999 yen (about £6.50).
