Even though this may be off topic, I apparently noticed that in your video of the Japanese preheat circline fluorescent pendant fixtures in the antique house, the lamps inside them actually consist of the following: 30W energy saver replacement lamps for 12 inch 32W circline fluorescent lamps and also 28W energy saver replacement lamps for 9 inch 30W circline fluorescent lamps (you mistook those for 8 inch 22W circline fluorescent lamps, which are not really such a thing in Japan, I have seen an older double circline pendant fixture on a Japanese Auction site that apparently had a 22W circline lamp, but it had some metal end caps that were not joined together). In fact, Japan apparently has some 20W circline fluorescent lamps that are the size of our 22W circline fluorescent lamps plus 18W energy saver lamps meant to replace them. In addition, you also sighted some rapid start fixtures that take 40W T10 tubes rather than T12 tubes. In some cases, these 4 foot T10 tubes are sometimes rated at 36W for energy saving applications in rapid start fixtures. Interestingly, T12 fluorescent tubes in Japan under 8 feet are extremely hard to find and are often sold at high prices. Additionally, you should also be able to safely operate most preheat fluorescent fixtures from Tokyo since that region of Japan uses the 100V 50Hz standard and preheat ballasts rated for 100V 50Hz should be safe to operate on 120V 60Hz since if you want to operate them on 60Hz, you would need to increase the voltage to a slightly higher level to get the lamps to properly operate. Ideally, those ballasts would work best on 110V 60Hz supplies, which means that running them on 120V 60Hz should do little harm to them. Additionally, I also see that incandescent lamps are still commonly sold in Japan and plus, there are plenty of 110V lamps still being sold as well, which means that you should be able to safely operate them back home as well.
