Takayama Showa Museum / Hida-Takayama -- I think the Japanese are in love with the period of prosperity they experienced after World War II and continued into the 1980's. That might explain why there are Showa-era museums throughout the country including at least two different ones in Takayama. While the Retro Museum was a lot more kid-friendly, this one was targeted to grown-ups.
In particular, it probably has a special appeal to baby boomers who may have faint memories of those days of yore. Even though I wasn't raised in Japan, the gadget-filled rooms evoked instant memories of my parents' house. They never threw anything away, so the thrift shop vibe here generated an instant kinship for me. They have rooms dedicated to various appliances around the house...
Portable TV sets, washing machines, rice cookers, cameras. There was familiar mid-century bric-a-brac as well as extensive vinyl record and fan magazine collections. When I saw photos of Pink Lady plastered on the wall, I knew I was home (Photo 6). If no such memories exist for you, consider this more of an archeological curio shop. OK, maybe a junk shop if you want to dismiss it. Admission was ¥800.
