### 1/5 — Didn’t add much

*2019-10-15*

When scanning to QR I thought I would get a translation & detail off the items. It you actually only gave a photo of some of what you were seeing  & a heading which was on the label in the display anyway 
What would have been useful was a translation or explanation of the large texts in the wall. For an English speaking visitor it was poor although I’m sure Japanese visitors would get much more from the visit
