Visitors to the exhibition asked, how do I start the charcoal in the hibachi,
I make a fire in the shichilin outside and throw the charcoal on the fire.
You will notice that every house no mater how small, if it was built before the Showa Era has a separate door for the kitchen. This was to go out to start the fire, and to bring that fire back inside for cooking. My little studio nagaya has one.
