Seedlings from sea-borne seeds of various tropical and subtropical plants were found on Daiho Coast, located on the southernmost part of Fukuejima Island of the Goto Islands in Nagasaki Prefecture, southwestern Japan. Many seedlings were found like never before in species number and individuals. These species were Hibiscus tiliaceus, Ipomoea pes-capre, Mucuna sloanei, Operculina turpethum, Vigna maritima and two Fabaceae species.

Seeds of Macropsychanthus (Fabaceae) drifted on the coasts of Japanese islands were classified to seven species based on about 700 seed collections. The identified species were M.comosus (G.Mey.) L.P.Queitoz & Snak, M.ferrugineus Merr., M.hexander (Ralph) L.P.Queiroz & Snak, M.javanicus (Benth.) L.P.Queiroz & Snak, M.umbrinus (Elmer) L.P.Queiroz & Snak, M.wilsonii Standl.) L.P.Queiroz & Snak, and an unknown species（M. " mable " tentatively named). Most frequent seeds are M.hexander, which were about 80％ of all drift seeds of Macropsychanthus. The following frequent species were M.wilsonii (5％), M.comosus (4％), M.ferrugineus (4％) and M.javanicus (3％). M.umbrinus and M. " mable " were rarely drifted and about 1％, respectively．The characters of their seeds were described.

Both ancient and modern borings are of interest to the paleontologist. Numerous clasts derived from the Late Miocene volcaniclastic sediments, mainly rhyolite, are washed ashore on Hamanaka Beach, Yoichi Town, Hokkaido. The rhyolite of the Kucchan Formation are indicated 6.7 Ma by K-Ar dating. Bored rhyolite cobbles including bivalve shells are collected on the stranded line, and recognized as the first record of rhyolite boring in Japan. The host rock are typical glassy rhyolite, with phenocrysts of quartz, plagioclase, biotite and apatite. The borings were produced by the rock-boring clam Penitella kamakurensis. The Clavate borings are assignable to Gastrochaenolites isp. due to incomplete for accurate identification.

One drifted dorsal valve of the genus Discradisca（brachiopod）covered with coralline was collected in Motoyama-misaki, Sanyo-OnodaCity, Yamaguchi Prefecture, Japan. Covering Discradisca with coralline is rare and is a valuable example for further understanding of its lifestyle and competitive interactions of sessile organisms.

It was pointed out that the previous records of drift fruits of Inocarpus fagifer were mistake for the seeds of Hedgsonia macrocarpa. The characteristics of the drift fruit of I.fagifer and the seed of H.macrocarpa were described. I newly recorded the drifting of I.fagifer and seeds of H.macrocarpa.

A single specimen of Dasyscopelus asper（Richardson,1845）which stranded at Tudumari-hama Beach, Iriomote-jimaIsland, Yaeyama Islands in the Ryukyu Archipelago. Although this species is one of the common species in the deep-sea of northwestern Pacific Ocean, there are no records of this species in the southern Ryukyu Archipelago. This specimen is representing the first record of the species from this area.
