Fate/stay night (Winter)

Google map of the places below

Places still missing from the map are as follows. Some of the interior shots which were fairly generic are omitted. Interior shots of western-style houses are included on the off chance that they are inside publically accessible western houses (as is certainly the case with the Tohsaka residence living room.)

If you know any of these, or know more which are missing, let me know! :-)
