The Asian sheepshead wrasse <\/strong>\/ Kobudai <\/em><\/strong>(Semicossyphus reticulatus<\/em>) was made famous by a dedicated sequence in the film Oceans<\/em> and, more recently in part one of BBC\u2019s Blue Planet 2,<\/em> which focused on the specie’s remarkable female to male transformation.
They can be easily be seen in T\u014dhoku<\/strong> between July and September on Sado Island (Niigata Pref.) and in Ryutoanjima\/Yotsushima (Yamagata Pref.). It is also common in Ch\u016bbu<\/strong>\u2019s Otomi and Ishikawa area (Toyama Prefecture) and on various Shikoku<\/strong> sites on the Seto Inland Sea.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Juveniles will usually avoid divers, but adult octopus are very curious, especially about divers with cameras sporting long strobe arms, which they will often try to pull away\u2026<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The smooth lumpfish\/lumpsucker <\/strong>(Aptocyclus ventricosus<\/em>) is cute (?) or at least quite odd-looking, and can be spotted, along with other small Cyclopteridae <\/em>in the winter months in Hokkaid\u014d, <\/strong>can is also spotted in the early summer months in T\u014dhoku, around the Oga Peninsula<\/strong> (Akita Pref.) and between January to March on Sado Island<\/strong> (Niigata Pref.) and in Namerikawa (in Ch\u016bbu\u2019s Toyama Prefecture), in the months of January to February.<\/p>

Another odd-looking lumpfish, Lethotremus awae<\/em>, is often seen in winter at Iwa or Enoshima in Kant\u014d\u2019s Kanagawa Prefecture, and is a real favourite of Japanese divers.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Ch\u016bbu\u2019s landlocked Gifu Prefecture<\/strong> might not be the obvious choice for a dive trip, and yet it is one of the best places to observe Japan\u2019s endemic giant salamander<\/strong> (Andrias japonicus<\/em>), that grow up to an impressive size of 1.5 m.
The best place to see them is in the freezing (find a drysuit!!!) mountain rivers of Gifu especially during breeding season, when the males are guarding the nests.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Koza River<\/strong>, in Kansai\u2019s Wakayama Prefecture, is another good place to observe Japan\u2019s endemic giant salamander<\/strong> (Andrias japonicus<\/em>), which can grow to an impressive 1.5 m in size. It is best to aim for mating season, when the males are guarding the nests.<\/p>

Another spot to see the salamanders is in Ky\u014dto\u2019s Kumogahata \/ Kamogawa river, during freshwater snorkelling trips.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

[CULTURAL NOTE ON JAPAN'S ICONIC SPECIES]<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

On a more local scale, other emblematic\/iconic species highly appreciated by Japanese divers include most \u201ccute\u201d or odd\/grotesque looking fish<\/strong> (fish with big eyes, round shapes, exaggerated features, clumsy in their movements), juveniles, small-sized\/tiny species <\/strong>and, importantly colourful fish and endemic species\/local variations of well known species<\/strong>, <\/strong>including common reef fish <\/strong>(butterfly, angel, damsel, clownfish, anthias, wrasses) and gobies, blennies and nudibranchs.<\/strong><\/p>

Japanese divers are often quite interested in local, endemic species,<\/strong> mirroring the way Japanese domestic and even international tourism tends to have a strong fixation on localism (including local food delights, some of which can only be sold locally, called products labelled chih\u014d gentei <\/em>\u5730\u65b9\u9650\u5b9a in Japanese).<\/p>

A good example of such an iconic endemic local species would be the Yuzen<\/em>, or Wrought-iron butterflyfish (Chaetodon daedalma<\/em>) endemic to the Nanp\u014d Archipelago\u2019s Izu and Ogasawara\/Bonin islands.<\/p>

This interest in the local delights of iconic endemic species, which is shared with many non-Japanese divers, does however extend to species that are less popular outside Japan<\/strong>, including smaller reef fish<\/strong> such as damsels and anthias, butterflyfish and angelfish, or gobies and blennies<\/strong>, that delight divers and UW photographers with their distinctive patterns, shapes and particularly colours, but that are more of a specialist interest outside Japan.<\/p>

Colours<\/strong> and patterns<\/strong> are especially important in Japan, as a quick glance at the production of renowned Japanese underwater<\/strong> photographers<\/strong> illustrates very well.<\/p>

When we were working on Thailand\u2019s Andaman Sea, Japanese guests would be strongly interested in fish similar<\/strong> to what they had back how, yet differing slightly<\/strong> in their features.
Same-same, but different<\/em>, as the local saying goes…<\/p>
