(0:36) The sills come pre-cut from the factory with a variety of joints cut into the sides and ends of the pieces. I’ve seen the same stuff used on houses in other construction videos from Japan.

Some of the bolts are thicker and longer than others, and will be fastened to the hold-downs on the vertical posts used to brace the building against seismic forces. Note the length of the anchor bolts-which must be long enough to project through the thickness of what look to be 6圆 or 8x8 sills.

This video shows a crew of Japanese carpenters installing sill plates on a stem wall foundation on a project in Otawara, a city 100 miles north of Tokyo. On residential projects, the frame is cut by computer-controlled equipment in a factory and delivered to the jobsite for assembly. Japan has a long history of timber framing, a construction method that fell out of favor in this country after the 1830s, when carpenters in Chicago invented balloon framing, an early form of stick framing that evolved into the platform framing used today. Timber framing remains popular in Japan, though the complex joints are no longer cut by hand except for special projects such as temples.
