Abstract from DBPedia
    An archipelago (/ˌɑːrkəˈpɛləˌɡoʊ/ AR-kə-PEL-ə-goh), sometimes called an island group or island chain, is a chain, cluster, or collection of islands, or sometimes a sea containing a small number of scattered islands. Examples of archipelagos include: the Indonesian Archipelago, the Andaman and Nicobar Islands, the Lakshadweep Islands, the Galápagos Islands, the Japanese Archipelago, the Philippine Archipelago, the Maldives, the Balearic Isles, the Bahamas, the Aegean Islands, the Hawaiian Islands, the Canary Islands, Malta, the Azores, the Canadian Arctic Archipelago, the British Isles, the islands of the Archipelago Sea, and Shetland. They are sometimes defined by political boundaries. For example, the Gulf archipelago off the northeastern Pacific coast forms part of a larger archipelago that geographically includes Washington state's San Juan Islands; while the Gulf archipelago and San Juan Islands are geographically related, they are not technically included in the same archipelago due to manmade geopolitical borders.

    諸島(しょとう、英: Archipelago、英: Island group)とは、複数の島がまとまって存在するものをいう。島が塊状に集まったものを群島(ぐんとう)、島が列状に並んだものを列島(れっとう)ともいうが、はっきりした定義はない。地名としての使い分けは歴史的あるいは慣習的なものによるところが大きい 。
