Consei
A lunch restaurant across from Mitsukejima-so inn. The signature dish is Sazae-don — turban shell braised in sweet soy sauce atop rice layered with arame and mekabu seaweed (sazae's natural food). A unique expression of Nishinoshima's sazae culture. Featured on official tourism sites as the origin of Oki's 'Goshimaji Gourmet.' Note: sazae fishing has off-seasons (May–June, Oct–Nov) — advance confirmation recommended.
Ranks high in Tabelog's Oki area with 29 reviews (substantial for Oki). 'Unique sazae-don style only on Nishinoshima.' 'The springy turban shell texture is superb.' Strong endorsement from both tourism association and official sites. Independent verification confirmed coverage on bewave.jp, Yahoo! Travel, and Nishinoshima Tourism Association.
