The story

Aska Istanbul: Refined Japanese Sushi on the Old Town Rooftop

The Kitchen and the Craft

Located on the fifth floor of Istanbul’s old town, Aska operates as a dedicated Japanese sushi bar. Atsushi Sugimoto shapes each piece directly in front of seated guests, while Anton Schmaus designed the space around transparency. The menu follows straightforward techniques rather than complex embellishments, letting the fish retain its natural texture.

A Skyward Setting

The dining room occupies a quiet corner that rises above the historic streets below. Tables sit close together, creating an intimate environment suited to smaller groups. Natural light filters through large windows during the day, shifting to soft artificial tones after dark.

The Schlemmer Recognition

Critics at the Schlemmer Atlas awarded Aska three and a half spoons in their 2026 edition, highlighting the consistent quality behind each plate. The guide specifically praised the exclusive atmosphere and the reliable execution of Japanese cooking traditions. Diners seeking a focused meal often reference this rating when booking their table.
