They have also lived close to water, listening to its flow and living in harmony with nature.
Deep in the rural mountains, this place is alive with the warmth of fire and the presence of water.
For those of us living in a restless modern world, it is a quiet refuge where we can return to ourselves.
Time spent here is a journey into the luxury of doing nothing, and into becoming one with the breath of nature.

Aichi Duck / Bamboo Shoots / Mountain Herbs

A dish reflecting the chef’s journey through time and place.

Aichi duck, from the chef’s home region, is prepared in the style of Apicius and coated with aromatic spices. Spring bamboo shoots are presented as both confit and purée.

A celebration of the vitality of the river.

Iwana trout from neighbouring Doshi is filled with a mousse of grilled trout and scallop, incorporating the flesh, head, bones, and liver before being finished over charcoal.

Watercress appears in two forms: the stems transformed into a smooth sauce, the leaves dressed simply with lime and salt.

Kanko-Yaki

A traditional speciality of the Aone and Tsukui region, reimagined through French technique.

Seasonal ingredients from the mountains and fields are wrapped in dough and baked until golden.

For early spring, venison, wild boar, and duck are combined with cured boar, butterbur buds, and fermented turnip leaves before being enclosed in buckwheat pastry.

Meringue / Cherry Blossom / Strawberry

A spring interpretation of the classic French vacherin.

Inspired by the sericulture once practiced in this historic farmhouse, the meringue takes the form of a silkworm cocoon.

Within lies a parfait of strawberry and cherry blossom leaf, accompanied by cherry blossom ice cream, balsamic reduction, and a strawberry-sakura bean paste sauce.

“Uka” refers to the moment of emergence from the cocoon — a quiet expression of renewal, and of spring’s fleeting beauty.

Ingredients and Water from Aone

Aone’s crops are rich in natural sweetness, nurtured by the temperature differences unique to the mountain climate. Freshly harvested ingredients arrive at the table with their moisture and nutrients intact, offering a vivid taste of the land. Wild vegetables and game are also locally sourced and fresh, prepared simply to bring out their natural qualities and gently restore the body.

The water here comes from the underground streams of the Tanzawa mountains, known as soft water rich in minerals. It is suitable for drinking as it is, and also for sake brewing. Baths filled with this abundant pure water are gentle on the skin, easing both mind and body.

This traditional house is estimated to be around 150 years old. Its massive 45-centimeter-square main pillars and supporting floor beams provide the structural strength that allows for open spaces with more than five meters between columns. Looking up at the roof framework, carefully assembled by hand in an age before heavy machinery, one feels a deep respect for the people who built it.
For the flooring and other materials, cedar was cut from the carefully maintained forests of Aone. The 30-millimeter-thick solid planks were naturally dried for about six months, preserving the wood’s natural fragrance, luster, and strength. Today, much timber is quickly kiln-dried, a process that can reduce the wood’s natural aromatic compounds. Aromatic compounds such as α-pinene and sesquiterpenes are known for their relaxing and calming properties.
