   “[T]he productions of Jeso, in particular, are as follows: konbu, or sea-cabbage, birds of prey for hawking, whales and other sea-fish, skins of otters, beavers, seals, and stags, castoreum, gold, silver, adamantine spar.”

   “The chief occupation along the shore is gathering the seaweed called kombu (something like our kelp, or quite the same), which is sent in such large quantities to China; and a certain amount of fishing is also done. The kombu grows upon submarine rocks, but for drying it a wide, flat space is needed, and the houses, therefore, are placed along the sandy beaches; and almost every beach however small is occupied.”

   “A kombu or kombu-shiitake stock is also quick and mineral rich and makes a fragrant base for broth or miso soup. Wipe a six-inch piece of kombu seaweed with a damp cloth to remove dust and excess salt. Place the kombu in a pot with four to six cups of water. Bring to a light boil and simmer for five minutes. Steep for five minutes. Remove seaweed and use stock. The kombu can be cut and used again in soups or other dishes.”

   “The Japanese tangles are called konbu and represent important genera of seaweeds which have been used as food since ancient times. […] Konbu is harvested mainly in the various coastal areas of Hokkaido during the period from the last ten days of May to the end of September. Konbu is mostly dried in the sun soon after harvest, but sometime^([sic]) in a hot-air drier depending on weather.”
