This store claims to be the oldest Japanese grocery in the United States!
The space itself, on 59th Street between Second and Third avenues, is not all that big, but an employee told me people call in orders from around the country, so its activities extend beyond the constraints of its retail location.
You will find Japanese both on the food and in the air here.
