    We created a photographic identification catalog of 10 Tursiops sp., sighted at Tsunoshima-island, Shimonoseki City, Yamaguchi Prefecture in March 2013. On the basis of morphology of beak and dorsal fin, they are thought to be Tursiops aduncus(Indo-pacific bottlenose dolphin). After that, we reconfirmed eight individuals at off Kawajiri, Nagato City, Yamaguchi Prefecture in April 2013. Additionally, some individuals were also refound at the north coasts of Yamaguchi and Shimane prefectures from July 2006 to April 2015. These sightings suggest that identical groups of T. aduncus have inhabited waters around Yamaguchi and Shimane prefectures in certain period. As there is little information of bottlenose dolphins in Yamaguchi and Shimane prefectures, we will continue to obtain sighting data and individual information to clarify their seasonal distribution and life history.

    This report follows up the previous report of “A preliminary report of whale flensing performance held in the Showa era in Japan” (Ishikawa 2014). Whale flensing performance (Kujira no kaitai shou) is one of the show businesses held in a bargain sale of local shopping center and supermarkets, or local festivals from 1970’s to 1980’s. A total of 48 cases that include 25 new cases were listed and it was expected much more record would be found in future. It seems more performances were held in 1970’s than in 1980’s and the whale flensing performance became in the early 1970’s at latest. Of those 47 prefectures in Japan, 21 were confirmed where the performances were held, and Osaka prefecture was the most frequent. Although an organizer of the whale flensing performance (host of the event) was a super market or grocery stores in many cases, a local nongovernment organization, such as the Chamber of Commerce and Industry also organized the performance frequently at various local festivals for the purpose of contribution to the development of local communities. A characteristic platform of the whale flensing performance was a temporal room with glazed sash fixed on the rear deck of a truck. It was called “Waku (frame)”, and was an idea to fulfill the demand of public health office. Although the whale flensing performances were also held on the temporal stage in the open air frequently, there were several cases that the local public health office did not issue a permit for selling of whale meat in the open air stage because of lack of facilities under a food hygiene law. Even though the whale flensing performance was in fashion for two decades long, there are very few records in literature. The Whale Laboratory continues to gather the information on this topic, because it should be recorded as aspects of whaling history and people’s life and culture in the Showa Era.

    I researched historical documents to find the influence of the Toyo Hogei Company and Roy Chapman Andrews (RCA) on modern Japanese cetology in early times. The predecessor of Toyo Hogei had uniformed in-house names of fin and blue whales and those names became the standard Japanese names. RCA was a pioneer who identified the scientific names of both toothed and baleen whales in Japanese waters through the direct observation of specimens. Japanese zoologists from those days also regarded him as a pioneer. Prof. Nagasawa Rokuro exchanged letters with RCA and discussed the scientific names of Japanese whales. The names of whales Prof. Nagasawa used in his paper reflected those discussed with RCA. It was the beginning of modernization for Japanese cetology when (1) Toyo Hogei made uniform the biological species names of whales out of necessity to publish their business reports, and when (2) RCA observed whale specimens and identified their scientific names in Japan.
