 This jellyfish is often seen in the Mediterranean Sea and has beautiful blue-purple appendages on its mouth and arms.

First breeding in Japan! Baby striped shark exhibit begins!

Aqua World Oarai, which has the largest number of shark species in Japan, was the first in Japan to successfully breed the striped shark, a member of the shark family, in an aquarium, and one young fish was born on March 2024, 3. The exhibition has started from today!

Newly born baby striped shark
Exhibition start dateFrom Thursday, April 2024, 3 
*Depending on the situation, exhibitions may be changed or canceled.
Exhibition placeSameko Room (5th floor inside the building, behind the Canadian otter tank)

 Our aquarium is the aquarium with the largest number of shark species in Japan, and we are actively engaged in breeding sharks, including Japan's first breeding of sand tiger sharks. So far, 27 types of sharks have been successfully bred in tanks, and 12 of them are the first to be bred in Japan! Striped sharks are benthic sharks, and were given their name because of the distinct black and white stripes that appear on their bodies for a while after they are born. This striped pattern becomes thinner when the total length exceeds 30 cm, and the body color of adult fish becomes light brown. Until now, there has been no example of breeding in an aquarium in Japan, and this breeding is the first in Japan!

newly hatched baby

Two pairs of two males and two females brought in in December 2021 were kept in a backyard aquarium for the purpose of breeding, and spawning was confirmed around November 12. The eggs were raised in a separate tank, and the babies hatched successfully on March 2, 2. The hatched baby is approximately 2 cm in size and is male. In the future, as a shark aquarium, we will not only enhance the shark exhibits, but also strive for breeding and research so that our visitors can learn more about the profound and fascinating world of sharks.

About Adastria Co., Ltd.

Adastria Co., Ltd. is a casual fashion store chain with approximately 30 stores in Japan and overseas, carrying more than 1,400 group brands such as Global Work, Nicoando, and Lawry's Farm. We will celebrate our 2023th anniversary in 70, and under the mission of "Play fashion!", we aim to become a "good community co-creation company" that creates an open community where people and information can exchange and creates new value. .


History of uniform renewal

Since 2020, Aqua World Oarai has adopted the concept of "Come on, a new world sea!", and in order to show customers a new side of the aquarium, we will be implementing various initiatives such as renewing each tank and program, and opening new facilities. We have been working on this. As an aquarium that continues to move forward, we have decided to review our uniforms in order to further pursue the concept of "Here we go, New World Sea!"

Staff wearing new uniforms

Previously, uniforms were coordinated by combining ready-made products, but in order to create the museum's first original uniform that incorporates the points to be considered in breeding operations and the requests of staff working in the field, a selection process was conducted by a proposal screening committee. Furthermore, the new uniforms were completed by adopting the proposals made by Adastria Co., Ltd.

Overview of new uniform

With total coordination produced by Adastria, we have introduced five new items: blousons, polo shirts (long sleeve/short sleeve), pants, outerwear (cold weather clothing), and hats. The shapes and colors of blouson and polo shirts vary depending on the service staff and breeding staff. The collar and hem of the blouson have a design appropriate for each job, and the animals kept at the museum are depicted on them.

The polo shirt's colors and striped pattern are inspired by the museum's symbol mark, making it a uniform that summarizes Aqua World Oarai's vision.

The meaning behind our symbol mark

The three rings represent the exhibition space that extends to "Oarai, Ibaraki, and the world's oceans" and the Earth's "past, present, and future," and express the "Kuroshio, Shiome, and Oyashio currents" that are characteristic of the coast of Ibaraki. The dynamism of the shark moving forward toward the future is also the silhouette of each citizen of the prefecture, symbolizing tomorrow's Ibaraki.

This symbol mark has been used at our museum since its opening 22 years ago.

Original textile (fabric) created especially for Aqua World Oarai

The blouson and pants of the new uniform are made of textiles with illustrations of creatures kept at the museum, such as the sand tiger crocodile, Canadian otter, and Humboldt penguin.

This is an original design depicting creatures swimming freely, with a navy blue base inspired by the ocean. The creatures shown in the illustrations can actually be observed inside the museum, so please take a look at the uniforms as well.

First use of sustainable material “Collagen Yarn” at an aquarium in Japan

The new uniforms are made of fabric made from collagen yarn, which is made from collagen peptide amino acids found in fish scales. This fabric is made from polyester thread made from a polymer bound with components extracted from the scales of waste generated during fish food processing. It is used for uniforms because it is smooth to the touch, wrinkle-resistant, and has good stretch.

In addition, by wearing uniforms made from sustainable fabrics made from reused materials that would otherwise be discarded, the aquarium staff's mission is to protect the environment of the oceans and rivers, and to tackle the environmental issues faced by living creatures on a daily basis. It expresses our intention to spread the word. This is the ``first in Japan'' to use fabric made from ``collagen yarn'' for both professional and aquarium uniforms.

Numerous special features designed for staff working at aquariums


All staff members wearing new uniforms came together as one.
Under the concept of “Come on, a new world sea!”, we will explore the charms of living things.
We aim to be an aquarium that delivers to everyone.!
