The world's best planetarium completed in Yokohama!
Hamagin Children's Space Science Museum Planetarium Commentator Kazu Yaho
This year, 2023 is the 100th anniversary of the invention of the world's first modern planetarium in Germany.
In 1923, the first planetarium, invented by a technician at Karl Zeiss in Germany, recreating about 4,500 stars and five planets seen from Germany, and was applauded from around the world. A few years later, it evolved into a Tzace II type with a function to reproduce the starry sky around the world and can project about 9,000 stars, further enhancing its reputation.
MEGASTAR-IIA, which achieved world record
In December 2022, the Hamagin Children's Space Science Museum (Yokohama Children's Science Museum) located in Yokodai, Isogo-ku, was renewed to the latest planetarium for the first time in 21 years.
100 years before the planetarium was invented, it was full of recreating visible stars. However, using an astronomical telescope, you can see that there are more stars in the sky.
If you reproduce even a star that was thought invisible, the planetarium will be able to experience a more realistic starry sky
Takayuki Ohira, the representative director of Ohira Giken, the world's smallest planetarium manufacturer, located in Tsuzuki-ku, Yokohama. In 1998, we developed MEGASTAR, which projected 1.5 million stars, more than 100 times the previous planetarium, and attracted worldwide attention as a new generation of planetarium.
What would you like to create the latest planetarium now?
In this way, a state-of-the-art planetarium projector MEGASTAR-IIA with 1.2 billion stars was created based on the latest observation data observed by the space telescope under the Gaia project of the European Space Agency. The planetarium projector has a part with a hole that represents a star original star, and the light of the ultra-high brightness LED passes through the star original, and is projected on the dome screen by the lens. The original version of MEGASTAR-IIA is a special product named GIGAMASK, which was completed through joint development between Ohira Giken and Sonny Music Solutions Co., Ltd.
Its precision is that the hole that represents the darkest star is less than one-fifth of a millimeter, which is less than one-fifth of a millimeter, and the gap between the star and the star is about 1/1000th of a millimeter. It is made with ultra-precision processing technology that processes thin metal films with lasers. MEGASTAR-IIA combines 32 GIGAMASK to recreate the latest universe on the ground.
MEGASTAR-IIA and Summer Starry Sky
The appearance of the universe that is reproduced using the latest technology is still "awesome." The starry sky visible from the earth is reproduced forever. If you observe the starry sky using binoculars or telescope in the planetarium, you can see dark stars like the real starry sky, and you can see the existence of nebulae and clusters. If you take a picture in the planetarium, you can see the stars in a dark star that cannot be seen with a telescope.
The latest planetarium recreates the natural starry sky that has been lost in large cities like Yokohama with the development of science and technology. At the same time, it will recreate the latest universe that can be observed with the development of science and technology on the ground.
I know it's amazing, but do you need the planetarium to have that technology? It's not visible, but isn't it meaningless if you can't see it? I think there are many people who feel this way.
Projected Ogula, Ursa Minor
As a matter of fact, from the eyes of the commentator who project the planetarium at MEGASTAR-IIA every day, I can't say that all the stars projected by MEGASTAR-IIA are not visible. However, as televisions evolved from CRT to flat-screen TVs and the resolution increased to full HD, 4K, and 8K, the amount of information and resolution of the world around us continues to increase with the advancement of technology.
If you are the children of the present and future who are exposed to the high-resolution world from birth. Isn't it possible to feel the universe that today's adult can't feel? You may feel the universe more beautiful, closer, and feel the universe. I also have such a sense of expectation.

"Maybe MEGASTAR-IIA in Yokohama is the best in the world?"
In November 2022, the Science Museum decided to challenge the Guinness World Record for the number of stars that can be projected in the planetarium. However, it is not easy to challenge the world record. Based on the detailed images taken in the planetarium, the astronomer teachers conducted various verifications, and the final result of how many stars could be projected three months later, in February 2023.
MEGASTAR-IIA, which can be measured by the science museum's technology, has at least 700 million stars. It is a new record that is five times higher than the previous record, and achieves the Guinness World Record!
The planetarium of the Hamagin Children's Space Science Museum, completed in Yokohama, is the world's best planetarium where you can see the world's most stars. (As of May 2023)
"Adults and children. Why don't you come and experience the best starry sky in the world?"
※Official notation of Guinness World Records
The most stars projected by a planetarium projector (one off) is at least 700,000,000 stars and was achieved by Yokohama Science Center in Yokohama, Kanagawa, Japan verified on 8 February 2023.
