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 and hiking around the massive park grounds, then head to Tokyo Sea Life Park aquarium, which is located within the park, to view hundreds of species of colorful marine life.

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 the Tokyo Metro Tozai Line and get off at Kasai Station. Travel time: 45 minutes.

Seaside recreation and relaxation

At approximately 778,000 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 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 the entire park in a single day. For those short on time, the park is even outfitted with a train line that runs around the area.

Watch the penguins play

The entrance to Tokyo Sea Life Park aquarium, located within Kasai Rinkai Park, features a giant glass dome that can be seen from almost anywhere in the park. The aquarium is home to over 600 species, and is especially famous for its Pacific bluefin tuna and penguin exhibits. Adults and children alike will enjoy watching the powerful bluefin tuna swimming in groups, and the Humboldt, southern rockhopper, fairy, and king penguins frolicking about on land and underwater.
