:Japan National Route 410

National Route 410 connects the cities of Tateyama and Kisarazu, spanning Chiba Prefecture's Bōsō Peninsula in a south–north routing. Its southern terminus lies at a junction with National Route 127 and National Route 128 in central Tateyama. It travels south from there towards the southern tip of the Bōsō Peninsula, Cape Nojima. Upon reaching the cape, the highway begins curving to the north heading through Minamibōsō and the former town of Chikura. It has another junction with National Route 128 in the former town of Maruyama, sharing a brief concurrency with the route before continuing north into the city of Kamogawa. The highway has a total length of {{convert|110.4|km|mi|sp=us}}.{{google maps |title=Route 410|url=https://www.google.com/maps/dir/35.3867912,139.9412486/34.9915713,139.8735148/@35.1802315,139.707259,10z/data=!4m61!4m60!1m55!3m4!1m2!1d139.9664328!2d35.3911203!3s0x60180b31b7e0d223:0xbde102304a473c78!3m4!1m2!1d139.9562109!2d35.4126555!3s0x6018749543415d1f:0x24b4bb5343218042!3m4!1m2!1d139.9709775!2d35.3883801!3s0x60180b25b733a803:0xfb11de969bc414c6!3m4!1m2!1d139.9860612!2d35.3883884!3s0x60180adda6261359:0x316f59f00185821c!3m4!1m2!1d140.0556847!2d35.3840087!3s0x6022a0e3999b1941:0xcada3b7ddcfd7245!3m4!1m2!1d140.0643502!2d35.2680548!3s0x6022a8f485c207c1:0x638af7a8263de6cd!3m4!1m2!1d140.0735692!2d35.2512269!3s0x6022a91c71f80a19:0x37b5441a725a74d6!3m4!1m2!1d139.954074!2d35.0373401!3s0x6017febe88357bd7:0xc99df6fefb492a99!3m4!1m2!1d139.9401651!2d34.9251078!3s0x6017e35e3d8f348b:0xdda6063a211eec3a!3m4!1m2!1d139.8834752!2d34.9037633!3s0x6017e53d1597d317:0x55b25c01c5ab9a5b!3m4!1m2!1d139.8279772!2d34.9197849!3s0x6017f0471915274d:0xd4abe10986d8e9e!1m0!2m1!2b1!3e0|access-date=19 April 2021}}

In 1902, the {{Nihongo|Yomachisaku Daiichi Tunnel|四町作第一隧道|Yomachisaku Daiichi Zuidō}} was completed using only hand tools along what would become National Route 410 in the city of Kimitsu. The tunnel is the second oldest tunnel that is designated as a part of a national highway in Japan.{{cite web|title=ビックリ道路大集合…！これが「酷道・怖道・険道」だ|trans-title=Several surprising roads.

National Route 410 was established by the Cabinet of Japan in 1982.{{Cite act|title=一般国道の路線を指定する政令|trans-title=Cabinet Order Designating General National Routes|via=Wikisource|url=https://ja.wikisource.org/wiki/%E4%B8%80%E8%88%AC%E5%9B%BD%E9%81%93%E3%81%AE%E8%B7%AF%E7%B7%9A%E3%82%92%E6%8C%87%E5%AE%9A%E3%81%99%E3%82%8B%E6%94%BF%E4%BB%A4|year=1965|publisher=Cabinet of Japan|language=ja|access-date=19 April 2021}} Construction began on the Kururi–Makuta Bypass of the narrow sections of the highway including the Yomachisaku Daiichi Tunnel in 1989.

On 23 December 2015, a {{convert|20|m|ft|sp=us|adj=mid|-long}} section of the Yomachisaku Daiichi Tunnel's shotcrete lining collapsed following a re-application of the supportive lining a month prior to the collapse.
