One thing that I noticed pertains to the roof tiles on things like the temple buildings. There are the onigawara, which are like gargoyles, or ornamental features, at the ends of ridges. Then there are the kawara tiles, which have a common motif on the ends of the eaves.

The problem here is that the buildings have different motifs on different sides of the buildings, where historically the motif is homogenous across all sides of the building

The western style seating also throws me through a loop, as traditionally, seating was floor level (for the most part). This can be a stylistic choice, however, and I can respect that.

There are a number of words that are spelled using Katakana, which is the alphabet for loan-words. A couple mistakes here were a little glaring for me, but I will have to go through them a little more thoroughly. One example was using it on a banner for Seafood, which the Japanese already have a word for (and thus, wouldn't use a loan-word for it). Another example is using it for the word Hostel, where it would more likely use the japanese word for a traditional style inn (Ryokan), in kanji of course.
