My son likes dinosaurs but he doesn’t love them so I never thought to visit this museum, that is until my daughter got a little older and we realised that she didn’t like dinosaurs she loves them! So we, not surprisingly, came out of this museum with a few more mini dinosaurs to take home with us. (They have a great little shop)
This museum is worth the effort it takes to get to it. We went by Shinkansen from Tokyo and then rented a car as we were staying around the area for 2 nights. The museum is impressive, it has a lot in it to see and we spent almost 3 hours there, which is unusually long for us in a museum but we all enjoyed it. The space is big too so that it doesn’t seem too crowded. After seeing the area and the ski resorts near by I would imagine that it would be a great place to go for a skiing weekend and then one morning go to the museum. Lake Biwa, which is Japans biggest lake is close to here too.
