Wash some okra and rub it with salt.
Boil some water on high heat. Then put in okra, lower the heat to low and let it simmer for about 20 minutes or until tender.
To make the marinade, heat mirin (rice wine) on medium heat till most of the alcohol evaporates. You can use Apple Cider Vinegar and Honey/ Maple Syrup as a non-alcoholic alternative.
Add some soy sauce, dashi powder, and 1 cup of water to the boiling mirin.
Pour the soy sauce marinade over the okra while it is still warm.
Let it marinate for 1 to 2 hours before serving.
To serve, place okra on a serving dish, drizzle with marinade and top with katsuobushi.
