Probably the best bang for the buck on Ishigaki. About a 5-10 minute walk from the city centre/bus terminal. Has bicycle rentals, and a large dryer for scuba equipment.
Rooms are spacious and comfortable. Floors are tile and not carpet because Ishigaki is super humid.
Free breakfast each day is excellent. Generally, the menu is: salad (cabbage, lettuce and "goya" bitter melon), corn, pickles, tamago (egg) sushi, Vienna sausage/meatballs, rice, miso soup and yogurt. Bread is also available. They do have curry-rice once in a while as well. Drink bar includes jasmine tea, hot/ice coffee, tea.
