Hitsumabushi

This is "Hitsumabushi". Fish(eel=unagi) on rice!
Hitshmabushi is originally from Aichi or Mie prefecture.
This Hitsumabushi is Asakusa style. Usually Hitsumabushi's condiment is special Japanese sauce called "tare", but Asakusa Hitsumabushi's condiment is salt.
Unagi is luxury food so Hitsumabushi is a bit expensive but I really love it!
If you like Japanese food, don't miss it!
