Combine 2 quarts water with the hojicha leaves and kosher salt in a large saucepot. Bring to a boil, and then reduce to a simmer, about 30 minutes. Strain out the tea or remove and discard the tea bags, and then bring the tea back to a rolling boil. Add the sea cucumber slices and cook quickly, just 30 seconds, and then drain and transfer to a bowl.
Toss the wakame and cucumber with the sea cucumber and a sprinkle of salt. Combine the sugar and rice wine vinegar in a separate bowl, and then pour over the cucumber mixture, tossing to coat. Drizzle with the sesame oil and garnish with a sprinkling of sesame seeds. Plate and serve.
Hojicha leaves are used to make a variation of green tea. You may also use hojicha tea bags if loose leaves are not available.
