The Inland Sea serves as a scenic and practical corridor through the novel’s Japan, but its beauty is shadowed by the lethal destination toward which one of its routes leads. Tiger Tanaka presents it as a place of history and island splendour; in the same breath, he makes it part of a journey to the Castle of Death, where scenery becomes the approach to a poison garden.

A route across islands

The Inland Sea appears in Tiger’s account of how people reach the Castle of Death. He describes a boat trip across its historically resonant waters, followed by a local train from the terminal harbour at Beppu to Fukuoka and then a walk or taxi ride along the coast. In that itinerary, the sea is not merely a view: it is one stage in a passage that draws visitors toward the castle.

The journey also connects with the broader movement of the novel’s travellers. The Murasaki Maru, a modern 3,000-ton ship fitted with the luxuries of an ocean liner, makes a day trip through the island-studded waters. Crowds wave it off as if it were beginning an Atlantic crossing, while groups with placards identify business outings, schools, and clubs among the passengers. The ship’s grand departure contrasts with the modest scale of its voyage, likened in the narration to travelling along a long lake.

Passage and spectacle

Aboard the Murasaki Maru, James Bond and Tiger sit in the first-class dining room, eating ham omelettes and drinking sake as the ship moves among the islands. Tiger points out whirlpools, jokingly likening them to specially designed lavatory pans for suicides. The remark brings the voyage’s light, companionable spectacle into contact with the death motif that has already attached itself to the Inland Sea route.

The waters also prompt Tiger to lecture Bond on Japanese culture. He raises the classical verse forms tanka and haiku and asks whether Bond has heard of Basho; Bond admits that he has not. The scene makes the sea journey a setting for Tiger’s effort to educate his guest, even as Bond’s ignorance and bluntness keep their exchange comic rather than reverential.

Beauty beside danger

Tiger’s description of the sea as beautiful and full of Japanese history forms part of a calculated contrast. The route’s scenic attractions lead, in his telling, toward the Castle of Death’s ramparts and garden, where paths, poisonous plants, and fumaroles offer different means of dying. The Inland Sea remains beautiful, but that beauty belongs to a route whose endpoint has been transformed into a national destination for suicide.

The novel sustains this contrast as the travellers reach Beppu at sunset. The next morning’s journey to Fukuoka will bring them closer to their destination, while that evening’s visit to Beppu’s volcanic “hells” makes the landscape’s destructive power visible in bubbling fumaroles, steaming mud, and erupting geysers. Against this progression, the Inland Sea is at once a passage through a lived, crowded Japan and an early stretch of the journey toward the Castle of Death.
