Oceanside attractions in a residential part of eastern Tokyo

Take a break from the hustle and bustle of the city with a trip to Kasai. Bordering Chiba Prefecture, this eastern Tokyo town is home to the expansive Kasai Rinkai Park. Spend a day picnicking, fishing, and hiking around the massive park grounds, then head to the Tokyo Sea Life Park aquarium, which is located within Rinkai Park, to view hundreds of species of colorful marine life.

  • Watching adorable penguins swim and waddle at Tokyo Sea Life Park

How to Get There

The main access point for the general Kasai area is Kasai Station, accessible via the Tokyo Metro Tozai Line. For the park and its attractions, the Kasai-Rinkai Koen Station on the JR Keiyo Line is most convenient.

From Haneda Airport: One hour by train, or 40 minutes by Limousine Bus to Kasai Station.
From Narita Airport: One hour and 45 minutes by train, or one hour by express bus services to Kasai Station.
From Shinjuku Station: Take the JR Yamanote Line to Takadanobaba Station. Transfer to Tokyo Metro Tozai Line and get off at Kasai Station. Travel time: 45 minutes.
From Tokyo Station: Take Tokyo Metro Marunouchi Line to Otemachi Station. Transfer to Tokyo Metro Tozai Line and get off at Kasai Station. Travel time: 35 minutes.

Seaside recreation and relaxation

At approximately 806,000 square meters, Kasai Rinkai Park is one of Tokyo's largest metropolitan recreational areas. Spend an afternoon exploring the expansive grounds, which are home to a wild bird sanctuary, Ferris wheel, barbecue areas, and extensive walking and cycling trails.

Make sure to bring a camera to capture the beautiful sunset views from the Ferris wheel. For similarly impressive scenery, go to the Crystal View observatory. This two-story glass structure offers unobstructed views across the park.

The grounds are so expansive you may have trouble seeing all of the park in a single day. For those short on time, the park is even outfitted with a train line that runs around the area.

Play with the penguins

Located within Kasai Rinkai Park, at Tokyo Sea Life Park, the enormous glass dome is a must-see. The aquarium tanks inside are home to over 600 species of marine life from across the world, and the facility is particularly famous for its penguin exhibition. Adults and kids alike will enjoy watching Rockhopper, Fairy, and King Penguins frolicking about on land and underwater.
