Spacious Two-Generation Home in Chiba's Chihara Area

Properties were only required to withstand moderate earthquakes (Shindo 5). Many suffered significant damage in the 1995 Kobe earthquake. A structural assessment is recommended — seismic retrofitting typically costs ¥1M-¥3M.

Enhanced requirements after the 1995 Kobe earthquake including mandatory ground surveys, wall balance calculations, and strengthened connections between structural components. The strongest standard.

365 days/year. National Strategic Special Zones (like parts of Osaka and Tokyo) allow year-round short-term rentals with no day limit. Minimum stay: 2 nights.

100-180 days/year. Local government has added restrictions such as banning operations during certain periods (e.g., school days, weekdays) or in specific residential zones.

60-100 days/year. Significant local restrictions. Common in areas with hotel industry lobbying or concerns about neighborhood disruption. May limit operations to weekends, holidays, or off-peak seasons only.

Under 60 days/year. The most restrictive municipalities effectively discourage minpaku. Kyoto, for example, limits operations to January 15 - March 16 only (~60 days). Consider a ryokan or hotel license instead.
