A Guest Room Off the Merchant's Lane
Not every room in a merchant house was for family or trade. On the northern edge of the Kubo property in Yasuda, facing the same back lane as the storehouse, stands a small detached building whose purpose was hospitality. Built in the Taisho era (1912-1925), it is a two-storey timber structure with a footprint of 22 square metres, three ken by two in the traditional module, roofed in a gabled cover of pantiles.
The ground floor holds a six-mat guest room with a toko, the recessed alcove that marks a space as formal and receiving. This room was used to lodge visitors, a detached quarter where a guest could stay a night apart from the working household. The outer walls are clad in iron sheeting as a protective measure, and on the lane side the building opens only on its upper floor, a reticence that keeps the ground level closed to the street while giving the guest room above a view outward.
Why It Was Registered
The detached room joined the national register on 2 October 2007 (registration number 39-0222, the first in the sequence of the Kubo listings), under the criterion of contribution to the historic landscape. Its value is twofold. As a building, it preserves the modest form of a Taisho guest quarter with its formal alcove intact. As part of a group, it helps hold the character of the lane.
The register notes that the detached room, together with the storehouse and the outer wall, orders the appearance of the passage it faces. This is the heart of why the whole Kubo property was listed under the landscape criterion: the individual buildings are plain, but in concert they compose a stretch of Tosa townscape that would be poorer for the loss of any one of them.
What to Look For
From the lane, the most telling feature is the arrangement of openings. The ground floor presents a closed face of iron-clad wall, while the windows appear only above, on the second storey. That vertical logic, blank below and open above, is worth pausing over: it explains at a glance how the building balanced privacy toward the street with light and outlook for the guest room within.
Set the detached room beside the storehouse a few steps away and the outer wall running west, and the composition of the lane becomes legible as a single designed stretch. The building is private and in use, so appreciate it from the public lane. Yasuda's old quarter is best taken slowly on foot, and the northern lane of the Kubo house is one of its quieter pleasures.

Q&A
- What was the detached room used for?
- It served as a guest quarter for lodging visitors, set apart from the main working household. Its six-mat room with a formal alcove was suited to receiving and accommodating guests overnight.
- Why does it open only on the second floor toward the lane?
- Keeping the ground floor closed to the street preserved privacy, while placing the openings above gave the upstairs guest room light and a view. It is a practical response to a building that fronts a public lane.
- What is a toko alcove?
- A toko, or tokonoma, is a recessed alcove in a Japanese room used to display a hanging scroll or seasonal arrangement. Its presence signals that a room was intended for formal use and for receiving guests.
- Can I go inside?
- No. The detached room is part of a privately owned property still in use and is not open to visitors. It can be viewed from the public lane on the north side.
