仮換地 (kari-kanchi) refers to "provisional land replotting" in Japan, a concept used in land readjustment projects. It involves temporarily reallocating land parcels to facilitate urban development or improvement projects.

During a land readjustment project, existing land parcels may be reconfigured to create a more efficient and functional urban layout. Kari kanchi allows landowners to continue using a portion of their land while the project is ongoing. The temporary parcels are designated with the understanding that final adjustments and allocations will be made once the project is completed.

This process helps minimize disruption to landowners and residents, enabling them to maintain some continuity of use and occupancy. Kari kanchi is essential for smooth transitions during extensive urban planning and development efforts, ensuring that the community's needs are balanced with the goals of modernization and infrastructure improvement.

道路に面している (doro ni men shite iru) translates to facing the road or facing the street in English.

It typically refers to a property, building, or piece of land that has its front side directly adjacent to a road. This is a common term in real estate and urban planning in Japan, indicating the location and accessibility of a property.

下宿 (geshuku) refers to a type of lodging or boarding in Japan. It typically involves renting a room in a private home or a boarding house, where the landlord may provide additional services such as meals and cleaning. This arrangement is often more personal and home-like compared to staying in a hotel or renting an apartment.

Geshuku is commonly used by students, single workers, or individuals who need temporary accommodation. It provides a more affordable and convenient living option, especially for those who prefer a more community-oriented or family-like environment.

底地 (sokochi) refers to "land underlying leased property" in Japanese. It is the land that is owned by one party but leased to another party who uses it, often for building purposes. The owner of the sokochi is entitled to receive rent from the tenant who uses the land.

In real estate and property law, sokochi is an important concept because it distinguishes the ownership of the land from the ownership of any structures built on the land. This type of arrangement is common in urban areas where land is leased for commercial or residential development.

Understanding sokochi is crucial for property transactions, land development, and investment decisions, as it involves navigating the rights and obligations of both the landowner and the lessee. This includes aspects such as lease terms, rent payments, and the eventual return of the land to the owner after the lease period ends.

共益費 (kyoekihi) is a Japanese term that translates to "common area maintenance fee" or "common service fee" in English. It refers to the charges levied on tenants or property owners for the maintenance and upkeep of shared facilities and common areas in a building or complex. These fees typically cover costs such as cleaning and maintenance of hallways, lobbies, and other common areas, utilities for shared spaces like electricity and water, security services, landscaping and gardening, and repairs and maintenance of shared equipment and infrastructure. Kyoekihi is commonly applied in residential buildings, commercial properties, and office complexes. It ensures that all tenants or owners contribute to the upkeep of the common areas, maintaining a clean, safe, and pleasant environment for everyone. The amount of the fee can vary depending on the size of the property, the level of services provided, and the specific agreements in place.

権利金 (kenrikin) is a Japanese term that translates to "key money" or "premium" in English. It is a non-refundable payment made by a tenant to a landlord or property owner when leasing commercial property, such as a store or office space.

Key money is often required in addition to the usual security deposit and rent. It serves as a form of goodwill payment to secure the lease and may also be seen as compensation for the landlord's investment in the property or its location. The amount of key money can vary depending on factors such as the property's location, size, and market demand.

In some cases, key money can also be associated with the transfer of business rights or other intangible assets related to the property. It is a common practice in Japan, especially in the context of commercial real estate transactions.
