I can't say that I am particularly surprised that it is not something more, but that is OK. The house is indeed amazing, but really it is going to be a long time before I can repair the damage done to it. The photos in those albums show me removing a couple of walls that were put up in the house to divide it for a tenant. They screwed the wall into the shoji track inside and the amado track outside.
Additionally, a previous owner left almost all of the amado (20 out of 24) outside uncovered, and the wood panel rotted out, so they screwed 1/2 inch plywood onto the door frames. The amado when whole, could be lifted with one hand. With the plywood, they weighted roughly 50+ lbs. They ended up stacking all 20 of them on the deck near the stiars and the weight (about 1000 lbs) over the course of about 10 years caused the deck and the amado track to sag.
The tatami (original and solid rush stalk core) were probably not beaten or taken outside for a good 20 years or more, the covers were allowed to get really worn and beaten up (the tenant had a dog that she let on the tatami and she wore shoes on it). We found a guy on Oahu that can repair them. He said he could come over to our island and do it for like 300 per mat (3x 8-tatami rooms = 24 mats).
The tile roof has probably never really serviced since it was installed. A previous owner said that it was leaking heavily when they bought it, and that he got up and shifted some tiles back into place and that stopped the leaks, but there is evidence of more leaking, and many of the tiles are raised off of the tiles below.
The electrical is a joke, most of it is original to the house (installed 1963) and is aluminum 2-cable wiring, very dangerous from a fire standpoint as it gets older. All of that is going to have to be pulled out and re-run. The plumbing throughout the whole house is a hodgepodge, and will also require redesign and re-install.
And lastly, and most alarmingly, the termites have been doing a number on the house for some time. Since the roof tiles will break if someone walks on them in their current state (and fixing it is going to run me about $25K) I can't get it fumigated, so looks like I am going to have to use the Orange Oil solution, but that is about $5K by itself. I certainly have my work cut out for me. As I said, it will take a while to repair the damage that absentee landlords (and people who did not know what they had) did to it.
Thanks for the info! If ever we get the place fixed up, and I have no doubt that we will, I think a nice addition will be a sword or two for display, but I think I will save up for something more authentic than something pumped out of a Chinese foundry.
