A Hotel in Kasai Rinkai Park, ideal for both leisure and business.

Located within the expansive Kasai Rinkai Park spanning 240,000 tsubo, surrounded by lush greenery and sea breezes, is the urban resort Hotel Seaside Edogawa. Just a 15-minute train ride from Tokyo Station, it offers an unexpected tranquility and relaxation. Here, you can enjoy the chirping of birds, the vast sky, and the timeless ebb and flow of the tides. It serves as a base for bay area sightseeing, gatherings with loved ones, weddings, and business meetings, catering to a variety of needs.

  • This was our second stay with children. Last time, we stayed after visiting Disney.Located inside Kasai Rinkai Park, it’s perfect for letting kids play.This Plan included breakfast, and the food was excellent—no surprise given it’s part of the Okura group.Dinner wasn’t included in the Plan, but we used the restaurant and it was delicious as well.The large public bath was clean and spacious. There aren’t many Hotels in Tokyo with such a large bath, so it was very relaxing.The staff were very kind and helpful, especially to our child.They also stored our luggage on both check-in and check-out days, and we could rest in the lobby and reorganize our bags, which was a big help while spending time in the park with our child. Thank you very much.

  • We stayed here to visit a nearby theme park. We had seen photos of the Room, but it was more spacious and comfortable than we expected. There is also a large public bath, which was very relaxing. It was great that the toilet and bathroom in the Room were separate, but my daughter mentioned that it was inconvenient that there were no partitions between the shower booth, bathtub, and sink area. Everything felt clean, and we especially enjoyed hearing birds in the morning, but on closer look we could tell some items—such as the curtains, lampshade, and bed base—were a bit worn with age, which was slightly disappointing. We would love to stay again next year.
