The schedule from acquiring a hotel site to breaking ground is governed by two different kinds of rules. There are the regulations that decide whether a project can be built at all — floor-area ratio, soil investigation — and, separately, the procedures that decide when work can start: posting a public notice board, briefing the neighbourhood, and filing a report, all under local ordinances for the prevention of disputes over mid- and high-rise buildings. This article compares the primary source documents of seven Japanese municipalities — Tokyo Metropolitan Government, its wards and cities, and designated cities — to line up how many days must pass between erecting the notice board and being allowed to file for building confirmation, then converts that waiting time into a land-holding cost per guest room.

From notice board to confirmation application: 15 to 60 days under the ordinances

Tokyo’s Ordinance on the Prevention and Settlement of Disputes Concerning the Construction of Mid- and High-Rise Buildings was enacted in 1978. It applies to buildings taller than 10m; in Category I and Category II Exclusively Low-Rise Residential Districts the threshold drops to an eaves height above 7m or three storeys or more above ground. Article 5 of the enforcement rules requires buildings with a total floor area above 1,000 sqm and a height above 15m to display the notice board from at least 30 days before the confirmation application, and all other covered buildings from at least 15 days before. The Metropolitan Government’s Q&A gives a worked example: a board erected on 2 March allows a confirmation application from 1 April under the 30-day category.

Within Tokyo, individual wards and cities add their own requirements on top. Shinjuku Ward places large projects — total floor area above 3,000 sqm and height above 20m — in a 60-day category (90 days where educational facilities are nearby), while Adachi Ward puts hotels and ryokan in its 60-day category. From 1 April 2026, Adachi Ward widened the radius of residents entitled to a briefing session for a hotel or ryokan from within 50m to within 100m. The ward explains the change as dispute prevention: the greater a building use’s impact, the wider the circle of residents who should learn about the plan early and have the chance to discuss it with the developer. Kodaira City sets out a sequence of notification within three days of erecting the board, a briefing session or door-to-door visits before the confirmation application, and submission of the report no later than 10 days before that application.

The designated cities follow the same skeleton. Sapporo covers buildings above 10m (above 15m in commercial and similar districts), requiring the notice board to be in place 30 days before the confirmation application and the report 10 days before. Fukuoka covers buildings above 10m, with the board from 30 days before and the report no later than 20 days before. Yokohama counts differently: the report on neighbourhood briefings is filed once 20 days have elapsed from the date the notice-board notification was submitted, and the city then issues a written opinion — as a rule within 30 days — which must be attached to the confirmation application documents. At the statutory minimum, that implies roughly 50 days from notification.

Set side by side, all seven follow the same order: erect the notice board, file the notification, brief the neighbourhood, submit the report, then apply for confirmation. What differs is the day-count category and the radius of the briefing, and both are designed to lengthen and widen as the building’s scale and use carry more impact. From a developer’s point of view, having those days and radii written into the text of an ordinance also raises predictability: the schedule can be built in advance. On the rules that decide whether a project is possible at all, we have covered zoning and floor-area ratio in Hotel Development Capacity 2026: Zoning, FAR & Land Price in 5 Markets, and separately analysed how designation of soil-contamination areas can stop a project before groundbreaking.

Nine in ten planned hotels stand four floors or higher, squarely inside the ordinances’ scope

Drawing on MLIT’s “Statistical Survey on Building Construction Starts and Dynamics,” MetroEngines Research & Consulting tracks N=70 planned or under-construction hotels with 50 or more guest rooms, totalling 15,517 rooms. Among the 66 with a known floor count the median is 14 floors and the tallest is 63; 60 of them (91%) have four floors or more. On typical floor-to-floor heights, four floors or more is a rough proxy for exceeding 10m, so most of these plans can be expected to fall within the scope of the mid- and high-rise ordinances. The 10-14 floor band is the largest with 27 projects, and 12 projects reach 30 floors or more.

By location (N=70), Tokyo leads with 19 projects, followed by Hokkaido with 8 (6 of them in Sapporo), Kyoto with 5, Chiba with 5 and Kanagawa with 5 (3 of them in Yokohama). All 19 Tokyo projects sit in the 23 wards, and among the 18 with a known floor count the lowest is 11 floors. Since large-floor-area projects in central Tokyo may fall into a ward’s large-scale category — Shinjuku’s 60-day tier, for example — it is worth checking the relevant ward’s category table while the site is still under consideration.

From notice board to confirmation application — where the seven municipalities are

Allow one to three months for the ordinance ahead of a 2.80-year build

HotelBank’s earlier analysis (Hotel Build Times: 2.80-Year Median, 1.96 Solo vs 4.00 Mixed-Use) put the median period from groundbreaking to completion for planned hotels at 2.80 years (N=56), with hotel-only projects at 1.96 years and mixed-use projects including offices or retail at 4.00 years. The ordinance procedure examined here sits ahead of that construction period. The statutory minimum is 15 to 60 days, but before the board goes up the developer must prepare briefing materials and studies of shadow impact and radio interference. Where a briefing session is held, the days between giving notice and holding it are added as well — Tokyo requires notice at least five days before the session.

On that basis, this article frames the period between site acquisition and groundbreaking that should be set aside for the ordinance procedure in three ranges: “one month,” close to the statutory minimum; “two to three months,” including preparation and the scheduling of briefing sessions; and “six months,” where repeated rounds of explanation are used to adjust the plan carefully. Against a median of 2.80 years (about 33.6 months), one month is roughly 3% and three months roughly 9%. Building the procedure into the programme from the outset also makes the scheduling assumptions easier to share with the funds and lenders that assess the opening date.

In holding-cost terms: ¥75,000 per room at ¥30M per room, 1% a year, three months

Time spent on the procedure can be restated as a land-holding cost (land price x annual rate x months / 12). Assuming a 100-room hotel site, we calculate across land prices of ¥1.0 billion, ¥3.0 billion and ¥5.0 billion and three interest levels: 1.0% a year, 2.375% (the modal short-term prime rate published by the Bank of Japan, as of 12 August 2026) and 3.25% (the long-term prime rate on the same basis). At ¥30 million of land per room and 1.0% a year, one month costs ¥25,000 per room, three months ¥75,000 and six months ¥150,000. Move the rate to the 2.375% short-term prime level and three months comes to ¥178,100 per room.

Per room, even the heaviest case — ¥5.0 billion, 3.25%, six months — is ¥812,500, while ¥30 million per room at 1% a year for one to three months stays within a band of ¥25,000 to ¥75,000. The absolute sums are small next to the land price itself, but the higher the interest level, the more the question of “how many months to allow” starts to bite. Putting the ordinance months into the programme at the point of site acquisition, and carrying them through the business plan as a holding cost, is a practical way to sharpen both the opening date and the financial projections.

Conclusion — treat the time as a schedulable step

The mid- and high-rise ordinance procedure follows a common sequence — erect the notice board, file the notification, brief the neighbourhood, submit the report — and across the seven municipalities the statutory minimum runs from 15 to 60 days. As Adachi Ward shows, placing hotels and ryokan in the 60-day category and widening the briefing radius to 100m, accommodation can be treated as a high-impact use subject to more demanding procedure. At the same time, 91% of the 66 planned hotels with 50 or more rooms and a known floor count stand four floors or higher, so most fall within the scope of these ordinances.

Developers building an acquisition schedule would do well to place one to three months of ordinance procedure ahead of the 2.80-year median from groundbreaking to completion. Funds and regional banks assessing the opening date can read the holding cost per room straight off those months and the prevailing interest level. For residents, municipalities and developers alike, the procedure is a shared rule for making a plan’s outlook visible — and the earlier it is built in, the more predictable the project becomes.
