Honestly surprised, very good value for 400 yen, spent over 3+ hours and would reccomend for adults and kids. Really great variety of sciences, biology, genes, maths and physics, to even household and every day life. Although all of the reading was in Japanese, most of the interactive parts had English or were intuitive to watch or do. One negative though, all of the kids running around like monkeys. The planitarium would have been nice to do but many of the sessions were booked out by school excursions. If you want to do this for an extra 400 yen you should book in advance but 3 hours of the regular exhibit is plenty.
