This is a really cool industrial museum up in the hills of Tenri. Exhibits everything from Sharp's first mechanical pencils back in the 20s up to their modern output. Lots of cool computers on display like the X1 and X68000.

There's also an exhibit showing their flat screen production technology, solar power systems, and some interesting display technology like transparent displays.

It's located up in the hills so you'll need to take a bus from Tenri. You will also need to call ahead to make a reservation, entrance is 1000 yen for adults, and there's also a museum gift shop that sells replicas of the original mechanical pencils.
