Thanks for the posts @pHilpineS . Nice collection of tools!
Regarding the yellow handle screwdriver, there are two variations. The earlier variant has the katakana "TEQ" Toyota logo like in your first picture. The other is essentially the same as the first, but without the katakana logo. I don't know exactly what year the earlier driver became available, but I estimate 1968. That earlier variant existed until the early 70s by my best guess, when Toyota removed the katakana logo. The variant without the logo was found in tool kits of several different Toyota models (including 40 series Land Cruisers in 1972 though 1983). A screwdriver with a black handle replaced the yellow-handle screwdriver at some point.
The 250mm angle wrench absent of "Made in Japan" was still made in Japan. Just like the screwdrivers, there were different iterations of the wrenches throughout the years, with different markings. The 250mm wrench in your photo has a small oval pad on the front, and that variation was found in early Toyota Land Cruisers. The 200mm wrench was not included in any 20 or 40 series Land Cruiser tool kits.
