Great location - only 30 seconds to a minute away from the station so we didn't have to stay out for too long while it was super hot. The hotel lobby is on the 9th floor so have to take the elevators there first.
The breakfast buffet is amazing with the variety of Japanese appetizers and then various meats and fish like pork belly, oyakodon, grilled salmon, some mini sausages, and what seemed to be boiled/soft bacon. There's also a station with miso soup, white rice, corn rice, rice porridge, and Japanese rolled omelettes. Also an area with mini sourdough buns, small pieces of toast, croissants, chocolate danishes, strawberry jam and orange marmalade, and cereal (corn flakes and frosted flakes). Since I stayed at a different Mitsui Garden hotel a few months ago, I had a coupon for a free breakfast, though the usual price of 3850 yen is fairly inexpensive for the quality IMO.
The room itself is sufficient. I chose the superior room with 1 queen bed which was 23.5 square meters/252 square feet. There's a coffee table but since our luggage (2 backpacks and 1 carry on) took up pretty much the entire area/sofa, it was kind of cramped to sit there.
For outlets, I recall each of us had two USB-A and two regular outlets (can't remember if type A or type B) next to the bed. There were a few more regular outlets around the room.
The bathroom area is slightly separated from the rest of the room by a mirror and sink and the toilet and bathtub/shower are separated as well. It's the typical Japanese kind where the entire room is for washing and bathing.
