Pre-reading Note: Why Use "Ordinance Restrictions" for Comparison?

Japan's short-term rental/homestay regulation typically follows a "national law framework + local ordinance enhancements + enforcement interpretations." The same property may have completely different operational windows and compliance thresholds in different cities (or even different wards within Tokyo).

To avoid turning the discussion into "generalizations," this article adopts three principles:

1. First, provide the national baseline: The Residential Accommodation Business Act (New Minpaku Law) requires notification and sets an annual maximum of 180 nights, while allowing local governments to impose stricter restrictions through ordinances.

2. Tokyo, using "Shinjuku Ward" as an example: Tokyo operates on a "ward-level decentralization," with Shinjuku Ward serving as a representative sample—most typical, with the clearest information disclosure and explicit restrictions on "residential exclusive zones" (but not equivalent to all wards).

3. Osaka distinguishes two paths simultaneously: In Osaka's short-term rental practices, besides "Residential Accommodation (180 nights)," the "Special Zone Minpaku (Tokku Minpaku)" path under the National Strategic Special Zones is common, with different mechanisms and restrictions, especially regarding minimum stay requirements.

When creating content and pages, it is recommended to include the "city/path" in the title: e.g., "Kyoto City Residential Accommodation," "Osaka City Special Zone Minpaku," etc., which can significantly improve search intent matching.

The following are the "national law foundation" that all three regions must adhere to (establish a unified understanding before creating tables):

• Annual Maximum (180 nights): The Residential Accommodation Business Act sets an annual maximum for "days/nights of accommodation provided" and requires mechanisms that reflect regional conditions (local governments can further tighten restrictions).
• Notification/Supervision Authority: In principle, notification is made to prefectural governors, etc.; but "special wards" like Tokyo's 23 wards can handle supervision and ordinance-related tasks (resulting in significant ward-level rule variations).
• Periodic Reporting and Records: In practice, there are typically requirements for periodic operational performance reports and obligations such as guest registers/identity verification (different cities specify "how often to report, what fields to include, and how to retain records").

When creating tool pages, you can make the "national baseline" a fixed module, with each city page only detailing: what additional restrictions have been added locally beyond the baseline, to what extent, and how they are enforced.

Comparison Table (by "Regulation Restriction Items")

Notes:

• The "Tokyo" column uses the publicly available rules of Shinjuku Ward as a representative sample; other wards may be stricter or more lenient.
• "Osaka" lists both: A) Residential Lodging (180-night path) and B) Osaka City Special Zone Minpaku (Tokku) key differences.

How to Use This Table (Practical Advice: Toolization)

• When creating a "city entry page": First have users select "city + path" (Residential Lodging/Hotel Business/Special Zone Minpaku), then provide the corresponding Checklist.
• When creating a "project evaluation/property purchase page": Make this table a fixed module, informing users: the operable window for the same property varies greatly across cities, avoid misjudging based on experience from other regions.
• When creating "0-click high-display news today keywords": Write updates as "This week's update: Osaka City re-emphasizes 2-night 3-day rule / Kyoto Residential Exclusive Zone seasonal window / Shinjuku Residential Exclusive Zone weekday operation ban"—such "actionable change points" are more likely to drive clicks than writing news.

1) Osaka: Choosing the Wrong "Path" or Misunderstanding "Overlapping Restrictions"

• The Core Lever of Special Zone Minpaku (Tokku): Minimum Stay Duration. Osaka City clearly stipulates that Special Zone Minpaku must be 2 nights 3 days (3 days) or more, not 1 night 2 days; and requires intermediary platforms to set the minimum bookable duration in accordance with this rule.
• "Overlapping" is Osaka's Most Hidden and Common Pitfall: Osaka City's explanatory document explicitly states—if the same residence is used for both Residential Accommodation (notification) and obtains Special Zone Minpaku certification, then all restrictions from both sides apply, resulting in the need to simultaneously comply with:
  • The 180-night annual limit for Residential Accommodation
  • The 2 nights 3 days minimum for Special Zone Minpaku
  • And obligations such as periodic reporting under both systems

You can phrase it as a "red text warning":

• "Tokku does not mean unlimited; overlapping restrictions can actually make it easier to fall into pitfalls."

2) Tokyo: Significant Differences Within the Same City (Taking Shinjuku Ward as an Example)

• Shinjuku Ward has made its levers highly "enforceable":
  • Residential Exclusive Zones set clear prohibited operation windows (Monday noon to Friday noon).
  • Requires neighborhood notification (in writing) and reporting to the ward.
  • The ward will publicly disclose notified residence information, reducing the space for "anonymous operation."
  • Imposes clear requirements on waste disposal and other living environment issues.

For content production, the most suitable approach for Tokyo is:

• First create "Tokyo Minpaku Regulation: Quick Check of 23 Ward Differences (2026 Update)"
• Then produce 3–5 "Ward Sample Pages" (Shinjuku, Shibuya, Setagaya...), each following the same template output:
  • Area restrictions
  • Period/time restrictions
  • Neighborhood notification
  • Public disclosure/reporting
  • Penalty triggers

3) Kyoto: The "Seasonal Window" for Residential Exclusive Zones is Extremely Strong

• Kyoto City adopts a "only open during off-peak seasons" approach for Residential Exclusive Zones: in principle, restricted to January 15 noon to March 16 noon.
• Also emphasizes: annual calculation cycle, 180-night framework, and bi-monthly periodic reporting (number of accommodation days, number of guests, etc.).
• For owner-absent operations, Kyoto City documents also clarify management system points such as "10-minute arrival (approximately 800m)."

Tool-oriented writing suggestions for Kyoto content:

• Provide users with a "calendar-style" module:
  • Allowed operation window (bookable)
  • Prohibited operation window (only long-term/monthly rentals allowed)
• Then include a "Residential Exclusive Zone Self-Check" process:
  • Confirm land use zone → Check if it falls under Residential Exclusive → Verify if exceptions apply (e.g., certified Kyoto Machiya) → Management on-site system
