Sen'nyū is a deeply immersive work created during Meitei's residency in the hot spring city of Beppu, commemorating its 100th anniversary. Known for his "Lost Japan" series, Meitei captures the essence of onsen culture through field recordings and ambient composition. The album unfolds as a single, meditative piece shaped by geothermal soundscapes, ancient baths, and the atmosphere of a city steeped in mist and memory. Sen'nyū marks a new chapter in his exploration of place, ritual, and environmental music, and is accompanied by his first photo book documenting his time in Beppu.
In the final month of 2024, Meitei arrived in Beppu, a city long steeped in vapor, myth, and mineral memory. Invited to create onsen ambient music commemorating Beppu's 100th anniversary, he immersed himself in the city's geothermal psychogeography, where sound rises from the ground and time clings to mist.

Known for his Lost Japan (Shitsu-nihon) works, which channel forgotten eras into flickering auditory relics, Meitei took residence in the warehouse of Yamada Bessou, a century-old inn perched by the bay. Over two weeks, he listened intently to steam, to stone, to the atmosphere itself. The resulting work, Sen'nyū, traces the inner spirit of onsen culture. Like water finding its path, the music emerged with quiet inevitability, shaped by Meitei's synesthetic sensibility and deep attunement to place.

Equipped with a microphone, he wandered Beppu's sacred sites: Takegawara Onsen, Bouzu Jigoku, Hebin-yu, and the private baths of Yamada Bessou. There, he captured the breath of the springs, bubbling mud, hissing vents, wind against bamboo, and the murmurs of daily visitors. These field recordings became the sonic bedrock of Sen'nyū, an act of deep listening that attempts to render even the rising mist and shifting heat into sound.

Unfolding as a single, continuous piece, Sen'nyū drifts like fog through sulfur and stone. It traverses the veiled madness of Bouzu Jigoku, the spectral resonance of Yamada Bessou's inner bath, and the hushed voices of Takegawara Onsen. It is a gesture of quiet reverence, for water's patience, the land's memory, and the hands that have bathed here for generations

Where Meitei's earlier works conveyed his personal impression of a fading Japan, Sen'nyū is grounded in tactile presence, music not imagined but encountered. Here, his practice moves closer to the spirit of kankyō ongaku, environmental music born from place, shaped by it, and inseparable from it.

As part of the project, Meitei conceived a two-day public sound installation inside Takegawara Onsen, culminating in a live performance. Bathers soaked in mineral-rich waters while submerged in sound, an embodied ritual of place, body, and listening.

Sen'nyū marks Meitei's first full-length work centered entirely on onsen and opens a new chapter of his Lost Japan project under the expanded title 失日本百景 (One Hundred Lost Views of Japan), a series exploring extant sites of longing still quietly breathing within contemporary life. The album will be accompanied by Meitei's first photo book, a visual document of his time in Beppu. A new layer is added to the world he has, until now, built only through sound.

Sen'nyū continues Meitei's devotion to Japan as subject, while opening new terrain: both ritual and remembrance, an immersion into the mineral soul of Beppu.

The album will be released on 8 August 2025 on 180g LP and CD, with mastering by Stephan Mathieu.
