The Renewal of Tokyo Sea Life Park

Project Overview

Objective

It has been more than 30 years since Tokyo Sea Life Park opened, and time has taken its toll on the facilities and equipment. The aquarium also needs to adapt to changing social situations in Japan and abroad.
To address these issues, a new aquarium will be constructed on a site adjacent to the current aquarium.
The aquarium will be reborn as a more attractive facility, featuring renewed exhibitions, spaces where visitors can experience the sea using the latest technology, and devices that provide new learning opportunities and experiences.

Considerations on Utilization of the Existing Facility

In the Tokyo Sea Life Park Renewal Project Plan formulated in October 2020, the Tokyo Metropolitan Government stated that, in parallel with efforts to develop a new facility, the current Tokyo Sea Life Park （hereafter “the existing facility”） should be studied for its potential for utilization and profitability after relocation of the aquarium functions to the new facility, and therefore is currently studying the utilization of the existing facility.

In September 2021, the Basic Concept for Utilization of the existing Tokyo Sea Life Park Facility was released, presenting a concept for the utilization of the existing facility and the viewpoints and direction of the study.

September 2021: Basic Concept for Utilization of the Existing Tokyo Sea Life Park Facility published
