Den
Japan
DEN is a restaurant in Jingumae, Shibuya, Tokyo, identified on its official site as DEN, with the entrance on Gaiennishi-dori Street at Architect House Hall JIA. The operator’s pages confirm that this is the Tokyo restaurant itself rather than a generic listing. The venue keeps a limited evening service, with opening hours shown as 18:00 to 20:00 and Sunday listed as the regular holiday. The reservation line and booking information are published directly by the restaurant. The restaurant is led by owner-chef Zaiyu Hasegawa, whose note presents DEN as a place for cooking that is meant to be welcoming and satisfying to guests. The current format is omakase only, so diners are not choosing from an à la carte menu. The menu changes according to seasonal ingredients, which means the dishes vary from day to day and the experience is shaped by what the kitchen receives and selects for service. Reservations are taken by telephone only, with the English site stating bookings are accepted Monday to Saturday between 12:00 and 17:00. The restaurant does not take online reservations or bookings through third-party services, and parties are limited to up to four people. Guests are asked to mention allergies or intolerances at the time of booking, although the restaurant cannot guarantee that every request can be accommodated. The restaurant’s published policies also set clear boundaries around service changes, with same-day cancellations or reductions in diner numbers charged at the full pre-fixed price. Taken together, the official materials describe a compact Tokyo dining room built around advance booking, a fixed evening sitting and a changing seasonal menu. Its identity is strongly tied to direct communication with diners, with the kitchen’s approach defined by omakase service and the practical limits of a small reservation-led operation.
