The move-in management fee is 30,000 yen (one-time only), and the monthly common service fee is 22,000 yen. Private rooms at First House Shin-Otsuka are available with monthly rents ranging from 51,000 to 70,000 yen. Through my experience managing finances and guiding residents as staff, I've noticed that having clarity on initial costs and monthly expenses makes budgeting much easier.
