Working a wind-shadowed harbour carefully produced nothing. Of the three moves for a tough day, which one actually paid? https://keystonebrand.jp/en/movies/20260820/ https://keystonebrand.jp/en/movies/20260820/ Thu, 20 Aug 2026 00:00:00 +0900 Sold in small batches under REVOLT, the brand that puts products out while they are still in development — and the whole thing caught on camera in a December 2024 session. https://keystonebrand.jp/en/movies/20260819/ https://keystonebrand.jp/en/movies/20260819/ Wed, 19 Aug 2026 00:00:00 +0900 Tip-run is thought of as a boat technique. Cast the same egi from the shore and what you need is not special tackle, but a different order of operations. https://keystonebrand.jp/en/movies/20260818/ https://keystonebrand.jp/en/movies/20260818/ Tue, 18 Aug 2026 00:00:00 +0900 Three hours by boat from Kagoshima, an island of some fifty people. Why we keep going back to Takeshima. https://keystonebrand.jp/en/movies/20260818-2/ https://keystonebrand.jp/en/movies/20260818-2/ Tue, 18 Aug 2026 00:00:00 +0900 The colour that worked at first light was not the one that worked once the sun was up. https://keystonebrand.jp/en/movies/20260817/ https://keystonebrand.jp/en/movies/20260817/ Mon, 17 Aug 2026 00:00:00 +0900 A torn squid-jig cloth can be re-wrapped with scissors, a needle, thread, a lighter — and a stapler. https://keystonebrand.jp/en/movies/20260816/ https://keystonebrand.jp/en/movies/20260816/ Sun, 16 Aug 2026 00:00:00 +0900 Across the hours either side of sunset the working colour changes hands — and how the light is handled decides the outcome. https://keystonebrand.jp/en/blogs/egisharp/20260509/ https://keystonebrand.jp/en/blogs/egisharp/20260509/ Sat, 09 May 2026 00:00:00 +0900 A spot you can only fish when the tide pulls out. Working the 1–3 m shallows dotted with bait and weed with EgiSharp size 3.8 V0+ 'Day Rock Brown.' A field report on how this updated take on Real Bait Brown produced a cuttlefish (Kouika) followed by an over-1kg bigfin reef squid. https://keystonebrand.jp/en/blogs/egioita/20260413/ https://keystonebrand.jp/en/blogs/egioita/20260413/ Mon, 13 Apr 2026 00:00:00 +0900 A 7 m/s crosswind. The usual size 4.3 got taken by the wind and became impossible to control. So I switched to the Egi Oita Purapura 7. Its weight tamed the wind, and a tension fall placed on the tide line landed a Red Monster. A field report. https://keystonebrand.jp/en/blogs/hikigata/20260406/ https://keystonebrand.jp/en/blogs/hikigata/20260406/ Mon, 06 Apr 2026 00:00:00 +0900 Keystone field report [April 5, moonlit spring tide]. When the squid won't react to jerking, take them with surface-draw eging. On the 3m-deep rocky shallows of Kitaiso, a Goto-type egi (squid jig) is slow-retrieved. Horizontal movement and a rising action on the pause trigger a reaction, and a solid hit comes mid-retrieve. Motion is technique; stillness is the way — this age-old drawing art lures the squid once more tonight. https://keystonebrand.jp/en/blogs/egisharp/20260328/ https://keystonebrand.jp/en/blogs/egisharp/20260328/ Sat, 28 Mar 2026 00:00:00 +0900 Keystone field report [Low-activity eging in late March] A cold egi means squid are present but sluggish. Instead of size 3.5, choose the size 3.8 V1 and tempt the squid near the harbor bottom with a large silhouette. After catching a bigfin reef squid (Aori squid) on Green Aji Base Blue, move spots and add two spear squid (Yari squid) on UV Leaf Green. https://keystonebrand.jp/en/blogs/events/20260323/ https://keystonebrand.jp/en/blogs/events/20260323/ Mon, 23 Mar 2026 00:00:00 +0900 KeyStone exhibited at KEEPCAST 2026 (Port Messe Nagoya), showcasing EgiSharp and products for ika-metal, omorig, and tip-run. The egi-painting experience corner was a huge hit with visitors of all ages, from adults to children. The panel of a giant over-4kg squid also drew plenty of attention. https://keystonebrand.jp/en/blogs/jadohen/20260319/ https://keystonebrand.jp/en/blogs/jadohen/20260319/ Thu, 19 Mar 2026 00:00:00 +0900 Keystone field report [March Jado Eging High Season]. Conquering the complex rocky shores of the crowded Yobuko area. Searching with Full Glow White, then catching fish back-to-back through a color rotation of Pink Glow White and Yellow Glow Purple. A field report where the stability of the Hayafuku-gata / Jado-hen size 3.5 V1 shone. https://keystonebrand.jp/en/blogs/jetchaser/20260221/ https://keystonebrand.jp/en/blogs/jetchaser/20260221/ Sat, 21 Feb 2026 00:00:00 +0900 Keystone field report — a February moonless night: shore eging from a rugged rocky shore in the north, plus deep tip-run off Naha. The triple-crown hook arrangement of the prototype JetChaser MT prove the true value of their high-balance design in strong currents. Once you hook up, you never lose them — stability, demonstrated. https://keystonebrand.jp/en/blogs/egioita/20260221/ https://keystonebrand.jp/en/blogs/egioita/20260221/ Sat, 21 Feb 2026 00:00:00 +0900 Okinawa eging, late season — eight fishless trips in a row. When EgiSharp Alpha size 4.3 drew no response, we broke through by sizing up to Egi Oita Purapura 7. Not 'making it eat' but 'making it notice' — the approach that led to the season's biggest bigfin reef squid (Aori squid). https://keystonebrand.jp/en/blogs/daybreak/20251119/ https://keystonebrand.jp/en/blogs/daybreak/20251119/ Wed, 19 Nov 2025 00:00:00 +0900 A November late-autumn tip-run field report. We tackled the technical, unsettled-depth conditions of the changing season by mixing four Daybreak colors, scoring back-to-back hits across every depth range — 20m, 30m and 60m. A detailed strategy on how color selection boosts your catch. https://keystonebrand.jp/en/blogs/egisharp/20251105/ https://keystonebrand.jp/en/blogs/egisharp/20251105/ Wed, 05 Nov 2025 00:00:00 +0900 Keystone field report [Early field test of the November new colors] A thorough test of EgiSharp's 4 new colors. Day Rock Brown shines on daytime rocky shores, while Aka-Samurai Meteor Glow Purple delivers in sight games. Haimurubushi Orange and Aka-Samurai Meteor Glow Red round out the lineup! https://keystonebrand.jp/en/blogs/squids/20251025/ https://keystonebrand.jp/en/blogs/squids/20251025/ Sat, 25 Oct 2025 00:00:00 +0900 In October 2025, KeyStone took part as a sponsor in CIAC2025, the international cephalopod conference held at the Okinawa Institute of Science and Technology (OIST). We visited the research site of Dr. Ryuta Nakajima and Kwahuu Ocean, who aim to commercialize land-based squid farming. As an egi maker, we reflect on the future of squid. https://keystonebrand.jp/en/blogs/jetchaser/20251020/ https://keystonebrand.jp/en/blogs/jetchaser/20251020/ Mon, 20 Oct 2025 00:00:00 +0900 Keystone field report [elevated position x fast current tough conditions] October spring-tide full moon at Saikai City breakwaters. Control the fast current with the JetChaser 2.6. First hit on Red Aji Orange, back-to-back catches on Ruru Purple, and two glow colors proven at night. https://keystonebrand.jp/en/blogs/daybreak/20251014/ https://keystonebrand.jp/en/blogs/daybreak/20251014/ Tue, 14 Oct 2025 00:00:00 +0900 Field report on the new Daybreak colors Red Aji Orange and Ruru Purple. Red Aji Orange excels at dawn and dusk mazume, while Ruru Purple is an all-around color, landing autumn squid one after another. Scheduled for release late October to early November 2025.
