Is there anyone in Tokyo that could sponsor OP one of those thermal emergency blankets?
They fold up very small, so you wouldn’t have to worry about carrying it/them. You could lie them on the ground, or over your blankets/cardboard. They reflect the heat back onto you instead of outward. Also good for keeping rain out.

These helped me earlier this year during a Texas cold snap.
Bad idea, candles will take out all the oxygen and you want to stay warm by keeping the windows shut (if you're in a truck). What people should do, is try and get mylar thermal blankets. Something like this and get them around to the truckers. You retain up to 90% body heat, so that should keep them toasty and warm. Not to mention, they're pretty cheap.
That's why you have to first notify the landlord every time they harass or complain. Inform him that you can't be any more quiet. After a short while, inform the landlord that you give up and tell him that It isn't helping you at all, trying to be quiet. Inform him that you will no longer live so restricted, since it is making zero difference in your experience.

Place one Mylar blanket in between your mattress and box spring (silver side down,) in the area of you head and torso. Take the last one and place it under your mattress pad.
Start laying the groundwork, so no one is surprised by your actions.
I’ve backpacked multiple years with a 30 degree bag, including in Yosemite and on the JMT. At lower elevations it kept me warm enough, but I was uncomfortably cold many nights at higher elevations And had a hard time sleeping. The 30 degree rating is an indication of what will keep you warm enough to live, not what will keep you comfortable.
You might consider bringing a Mylar (foil) emergency blanket with you: https://www.amazon.com/dp/B01LZN0KGB/ref=cm_sw_r_cp_api_i_wAgkFbBMARH34
It’s super light (only 2oz) and very effective. You can sleep in it with your quilt over the top and you will be completely warm.
I used this approach after one particularly cold and sleepless night in late Aug at the White Wolf campground in Yosemite. This camp is at a fairly high elevation, but not as high as passes on the JMT. Fortunately, I was still at the start of my trek and had access to my car. After freezing my arse off most of that night, I was worried about having similar nights in the backcountry. So I made a quick trip to Lee Vining and picked up an emergency blanket at a sporting goods shop. One of the best last min gear additions I’ve ever made. SinCe then, I’ve upgraded to a 10 degree bag, but still bring an unused emergency blanket with me when I’m hiking at higher elevations.
Good luck with your trek. Hope you have an amazing time!!
I really suggest buying emergency blankets! My friend bought some & helped super great with the cold. They fit easily in a Fanny pack & helped us not get cold https://www.amazon.com/dp/B01LZN0KGB/ref=cm_sw_r_cp_api_glt_i_YYDRTWX2KH6B696FFY0E
Any of the mylar ones will work great. It’s what they use for a lot of space applications because its so light but has great thermal properties. I got these
I just bought these: https://www.amazon.com/gp/product/B01LZN0KGB/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
This is probably going to be my last festival, so I am only going to use it once. Thanks for the comment!
