Overview (history, characteristics, attractions)

Akashi Municipal Astronomical Science Museum is a municipal astronomy and science exhibition facility located in Akashi City, Hyogo Prefecture. Its goal is to convey knowledge about astronomy, time, and the Earth in an easy-to-understand manner through planetarium projections, special celestial exhibits, and telescope observation events. Akashi City is located close to the Japan Standard Time Meridian (135 degrees east longitude), so it is also notable for its extensive collection of exhibits and monuments related to the meridian and time. With hands-on exhibits that can be enjoyed by children and adults alike, as well as special seasonal projections and events, it is popular as both an educational facility and a tourist spot.

Highlights

  • Planetarium projection: A realistic projection of the starry sky with commentary. There are many programs based on the season and theme, and special programs with commentators and voice actors are also held.
  • Permanent exhibits include a model of the solar system, explanatory panels about the universe and the Earth, and exhibits about time and the meridian. There are also interactive exhibits where you can learn by touching the objects.
  • Telescope observation events: Depending on the weather and time of day, you can observe the moon, planets, nebulae, and star clusters through a telescope (please check; most events are held outdoors).
  • Japan Standard Time (Meridian) Related: You can see an introduction to Akashi City's meridian, as well as exhibits and explanations related to the standard time meridian.
  • Seasonal and special events: Events are held throughout the year, including meteor shower observation events, astronomy lectures, and special exhibitions (related to comets and planets).
  • Rooftop observation space: On clear days, you can enjoy views of the surrounding area and the Seto Inland Sea (this varies depending on the facility).

Access (nearest station, transportation, etc.)

  • Nearest station: Within walking distance of Akashi Station on the JR Kobe Line (Sanyo Main Line) and Sanyo Electric Railway. Access by foot is generally recommended (approximately a 10-minute walk).
  • Bus: Local buses may be available. Bus stops and routes vary depending on your departure point, so please check the timetable in advance.
  • Car: There may be parking lots near the museum, but the number of spaces is limited, so we recommend using public transportation. You may also be asked to use paid parking lots in the surrounding area.
  • Combining it with sightseeing: Akashi Station is not a stop on the Shinkansen, but it is easily accessible from Osaka and Kobe, making it convenient for combining your visit with other nearby tourist spots (Akashi Park, Uonotana Shopping Street, Akashi Kaikyo Bridge, etc.).

Estimated stay (estimated time required)

  • Short-term visit: Exhibits only, approximately 30 minutes to 1 hour.
  • Typical visit: One planetarium show (approximately 45 minutes to 1 hour) plus 1.5 to 2 hours to view the exhibits.
  • Enjoy the view at your leisure: If you include participating in events, observation parties, and special exhibitions, you will need about half a day (2-4 hours).

Nearby spots

  • Akashi Park (Akashi Castle): A popular spot for strolling and cherry blossom viewing. Within walking distance of the Astronomical Science Museum.
  • Uonotana Shopping Street: A gourmet spot where you can enjoy fresh seafood and Akashi's specialty (Akashiyaki).
  • Akashi Kaikyo Bridge and Maiko Park: Easily accessible by car or public transportation, you can enjoy the view of the bridge and the sea.
  • Spots related to the Prime Meridian: This walking route includes monuments and information boards related to Japan Standard Time.

Things to be aware of (crowds, manners, seasonal precautions, etc.)

  • The planetarium has limited seating, and popular projections often sell out. We recommend arriving early, especially on weekends, public holidays, and during long school holidays, or checking ticket sales methods in advance.
  • Telescope observation is subject to weather conditions. Outdoor observation may be canceled, so please check the official website or call to confirm the status on the day.
  • The planetarium will be darkened during the day, so if you are bringing small children, please allow them time to get used to the light and pay attention to their safety.
  • Regarding photography: There may be restrictions on photography inside exhibits and the planetarium. Please follow the instructions of the staff and signs.
  • Clothing and season: If you are participating in a stargazing event, it may get cold at night, so please take measures to protect yourself from the cold according to the season. If you are observing outdoors, it may get dark, so please wear comfortable shoes.
  • Manners: Projections and viewing are primarily conducted in a quiet environment. Please be considerate and not to disturb other visitors.

Before visiting, it's a good idea to check the official website or social media for the latest information, such as opening hours, closing days, the day's projection schedule, whether there will be any observation events, and how to enter (whether or not you need to make a reservation).
