Room, bed, desk etc all okay but...
... The bath is a crime. Sure, this is a budget room so I don't expext a large bathtub or anything. But the toilet is unusable for a person of average proportions! The wall in front of the toilet is so close to the seat that you literally can't sit on the toilet without danger of things going "south". The Shinkansentoilet has more space than this.
I have been in many business hotels in Japan and I never seen anything like this. This is unacceptable.
On another note, there is an survey sheet laying on the desk asking about complaints against the staff on a personal level. You are even asked to describe the staff as detailed as possible if you don't know their name. So I guess you are supposed to take out your frustration on the low paid service staff? The hotel management must be horrible to work for and I won't support this with another visit.
Fix your toilets and treat your staff properly.
