日本における、約36km先まで光を照らす最大級のレンズが搭載され、且つ灯台の展望スペースまで登ることが出来る3基の灯台のうちの一つです。明治時代初期から現在に至るまで現役で稼働し、煉瓦製の建物として歴史的価値も高く、重要文化財に指定されています。
展望スペースまで昇降可能なのはいいものの、螺旋階段は非常にせまく、痩身の人でも何とかすれ違える程の幅しかありません。螺旋階段で人とすれ違う際は、どちらかが壁に寄せた上で停止し、すれ違う人を先に通す、という方法しかありません。譲り合って昇降するようにしましょう。また展望スペースも非常に狭く、風が強い日には帽子等が飛ばされる可能性は非常に高いです。転落防止用の柵はあるものの、足場には滑り止め等の対策は無いため、スマートフォン等を落とすとまず地面までそのまま落ちると思った方がいいでしょう。荷物はほとんど持たず、あるいは落とさないような工夫を凝らした状態で昇降した方がいいと思います。
1階部分は簡易的な展示ルームとなっており、犬吠埼灯台以外の灯台や海上保安庁の仕事の一部等が展示されています。展望スペースへの昇降と共に、出入口に段差があるため、車椅子等の障碍を持つ方は残念ながら（併設されている資料館を除き）利用出来ません。

Inubosaki Lighthouse is one of only three lighthouses in Japan equipped with one of the country's largest classes of lighthouse lenses, capable of projecting light approximately 36 kilometres out to sea, and allowing visitors to climb up to the observation deck.
The lighthouse has remained operational since the early Meiji period and is also of considerable historical significance as a brick-built structure. It has been designated an Important Cultural Property of Japan.
Although being able to climb to the observation deck is certainly one of the main attractions, visitors should be aware that the spiral staircase is extremely narrow. Even two relatively slim people can barely pass each other. When encountering someone coming in the opposite direction, one person generally needs to stop and move as close to the wall as possible to allow the other to pass. I would strongly recommend taking your time and being considerate of other visitors when ascending or descending the stairs.
The observation deck itself is also very narrow. On particularly windy days, there is a considerable risk of loose items, such as hats, being blown away. Although protective railings are installed to prevent visitors from falling, there do not appear to be any particular measures to prevent smaller belongings from slipping or falling through gaps around the deck. If you drop something like a smartphone, you should probably assume that it could fall all the way to the ground.
For this reason, I would recommend carrying as few belongings as possible when climbing the lighthouse, or at least making sure that anything you take with you is securely fastened and cannot easily be dropped.
The ground floor contains a small exhibition area featuring information about Inubosaki Lighthouse, other lighthouses in Japan, and some of the responsibilities and activities of the Japan Coast Guard.
Unfortunately, accessibility is quite limited. In addition to the narrow spiral staircase leading to the observation deck, there is also a step at the entrance. As a result, the lighthouse itself is not accessible to wheelchair users, although the separately located museum is an exception.
