A door of cedar bark, roof tiles for a nameplate, and a rope curtain with the same diagonals as the ceiling. ‘Ichiu’ means ‘under one roof’, and the ceiling is shaped like a roof to emphasise this point. The menu is faithful to the spirit of Chef Koichi Hamano, a man experienced in Japanese cuisine, particularly sushi. The evening begins with a cup of sake; soup and fried dishes are then served. After the sushi, takikomi gohan - rice with a variety of ingredients concludes the meal.
