Reviews center on voices saying that a caretaker is resident on site, which is reassuring, and on the spacious, thoroughly cleaned and clean large communal bath. The location close to Ishiuchi Maruyama ski area and the presence of a wholesale supermarket nearby are also cited. There are many short, highly rated posts, and no notable complaints are pointed out. The count is on the small side at 11. *The rating is the one registered on the building's Google Place.

Editorial review
The editorial team's assessment
Built in 1990 with 402 units in the Ishiuchi area, this building is treated by Angel Real Estate's building page as a single entry covering both Building A and Building B, and the three listings are also a mix of Buildings A and B. The listing price per tsubo is well above Mansion Review's reference index — a textbook case of a general-purpose index being pulled toward past disposal-sale prices in a location with few transactions — so the low index should not be read directly as a decline of the building. What deserves attention is the repair reserve fund: the level per square metre falls far below the MLIT guideline benchmark and is among the thinnest even within the Yuzawa-area buildings surveyed this time. As long as the reserve balance is not disclosed, the scope for an increase or a lump-sum levy needs to be factored in as a risk on the buyer's side. Units have baseboard heaters (in the Japanese-style room only) and electric water heaters, and none of the three listed units has a balcony, so an outdoor air-conditioner unit cannot be installed. The communal bath and sauna are currently suspended (a notice states that they are scheduled to reopen on 1 August), and the squash court is suspended as well.

Aspect 14
Plain-language glossary
Price per tsubo
The price per tsubo (about 3.3㎡, the size of two tatami mats). A unit for comparing properties of different sizes.
Holding-cost ratio
Annual upkeep (management fee + reserve fund) ÷ property price. The higher it is, the heavier the burden of simply owning.
Repair reserve fund
Money saved every month for future major repairs (exterior walls, piping, etc.).
Listing concentration
What percentage of all units are up for sale. A high figure means many owners want to sell.
Market price index
A reference price auto-calculated by portal sites. It can diverge from actual asking and closing prices.
Closing price
The price at which a sale actually closed (from Japan's MLIT Real Estate Information Library). It is closer to the real market than asking prices (the seller's quote). The figures here aggregate all pre-owned condominium deals across the municipality, mixing building ages and locations.
Management fee
The day-to-day running costs for cleaning, staff, hot springs, and so on.
man-yen (万円)
