In the height of summer, July, sea urchins and abalones feeding on seaweeds are very delicious. Especially it is the peek harvesting season for “ezo-bafun uni” (short-spined sea urchin) and “kita-murasaki uni” (northern sea urchin) at Rishiri Island in Hokkaido famous for the best sea urchins.
“Hikarimono” (all kinds of shiny blue-backed fish) is also very delicious. “Aji” (horse mackerel), “iwashi” (sardine), “tachiuo” (largehead hairtail), “tobiuo” (flying fish) contain good fat. These days more Edomae sushi restaurants use for nigiri “ibodai” (Japanese butterfish) popular in Kansai and Shikoku area.
“Shinko” (baby konoshiro gizzard shad), now grown larger, has been in the market since end of June but you may still enjoy the soft meat and the fresh taste.
