Pros: Rooftop pool is nice. Cheap booze sold by the pool. Rooms with patios overlooking the beach. Affordable. Lots of laundry machines. Free bike rental. On site parking plus overflow parking lot.
Cons: Not a good free breakfast (3 croissants), too many carbs. The room key system is rudimentary (a physical key with a fob with your room number on it), low security because if you drop it, someone will know which room it belongs to and can break in. They also impose a 50,000yen fine if you lose the key. Like, who made up this absurb fine? Will it really cost you that much to replace the key? I don't think so. Why not just have key cards like every other hotel.
