Cosmo Planetarium Shibuya — Attraction in Tokyo

This planetarium is located just a few minutes walk from the lovely Shibuya station and is pretty relaxing for a 600 yen (adult price) star show. I'm no planetarium connoisseur, but the whole set up was super clean, comfortable, and high quality. There are shows every 1.5 hours, with seating beginning 15 prior to the start but no entrance once a show has started. There was no English translation but even still the show was entertaining and the star gazing at the end was super chill. Would check out another one next time...

Quite a small planetarium, but the visuals are very nice. They have different themes for each of the sky shows throughout the day, and each one lasts around 45 minutes. You wouldn’t believe that there’s something like this is in the middle of shibuya, and for the price it’s definitely worth visiting. I feel like people of any age can enjoy...

There's another review that says you can't enter after the show starts, but I got in just fine.

The show I saw (there are several, I forget which one I saw) had a part that showed the evolution of the universe fast forwarded...it was really watered down though. Would be 4 stars if the show were 60min...
