Make a shallow cut around the base of the aubergine stem, then slice it in half lengthways. Place them on a baking tray.
Preheat the oven to 250°C. Cook them slowly for about 20 minutes until the skin is completely charred.
Take them out from the oven, then let them cool for 5 minutes.
Peel the skin from the base of the stem. Once peeled, cut them into bite-sized pieces.
Add the soy sauce, sake and mirin to a sauce pan over a medium heat without a lid. Once it starts boiling, add the shaved dried bonito and simmer for 2 minutes.
Turn off the heat. Take out and discard the shaved dried bonito. Let it cool.
Drizzle dashi soy sauce over the grilled aubergine.
