日本の 2024 年ドローン法は、100g 未満の屋内飛行に関して正確に何を変更しますか?

Japan's Civil Aeronautics Act amendment, which took effect in January 2024, carves out a clear exemption for drones weighing under 100 grams operated exclusively indoors. Previously, any drone — regardless of weight — flown in indoor public spaces like convention halls, sports arenas, or shopping complexes technically fell under the same regulatory umbrella as outdoor flights if the space was deemed "accessible to the public." The 2024 update removes this ambiguity. If your drone stays under 100g and never leaves an enclosed structure, the MLIT (Ministry of Land, Infrastructure, Transport and Tourism) requires zero paperwork. No operator registration, no flight plan submission, no Remote ID broadcast, and no permit fee of any kind. This is a significant operational shift for warehouse inspectors, event photographers, and indoor mapping professionals who previously needed to file 10-page permit applications for each venue. The 100g threshold aligns with Japan's existing risk-based classification system — sub-100g drones have kinetic energy levels low enough that indoor collision with a person presents negligible injury risk, a conclusion backed by JAXA impact testing data released in late 2023. For commercial operators, this means you can deploy a DJI Tello or similar micro-drone inside a client's factory for inspection work within 24 hours of being hired, with no regulatory waiting period. The exemption does not override private venue rules — if a building owner prohibits drones, that stands. But from a national aviation law standpoint, indoor sub-100g flight is now unregulated airspace in all 47 prefectures.

実際に 100g 未満の屋内免除の対象となるドローンはどれですか?

100 グラムのカットオフは、機体、バッテリー、プロペラ、小型カメラやセンサー モジュールなどの付属ペイロードの総離陸質量として測定されます。これにより、ほとんどの消費者向けドローンは検討の対象から外されます。たとえば、DJI Mini 4 Pro の重さは 249g で、屋内での使用であっても免除の対象外となります。以下は、真に対象となるモデルの内訳です。現在の 中古 価格は Reboot Hub です。

The DJI Tello dominates this category for practical reasons — 13 minutes of flight time is nearly double most competitors in the sub-100g class, and its SDK allows programmatic flight paths via Scratch or Python, making it the default choice for Japanese STEM educators and indoor inspection startups. Reboot Hub currently stocks 40+ Tello units across both Grade A and A+ conditions, with inventory replenished every 14 days from Shenzhen. The BetaFPV Cetus Pro appeals to FPV pilots who need a sub-100g indoor practice platform — its 38g weight leaves ample headroom for adding a micro action camera without breaching the exemption threshold. Crucially, none of these drones require Japan's Remote ID module (weighing roughly 3-8g itself), which would push several borderline models over 100g if attached. When buying pre-owned from Reboot Hub, every unit ships with its original battery and is weighed on a calibrated scale during the multi-point inspection to verify actual takeoff mass matches manufacturer specs within 2% tolerance.

日本で屋内用 100g 未満のドローンを飛ばすのにかかる費用はいくらですか?

The total entry cost breaks down into three components: the drone itself, shipping, and optional accessories. With Japan's indoor exemption eliminating all permit fees, your only hard cost is hardware. A Pristine Pre-Owned DJI Tello (Grade A) from Reboot Hub costs US$68. DDP shipping from Hong Kong to Tokyo adds US$22, bringing the landed total to US$90 — roughly HK$704 at current exchange rates. Compare this to buying a new Tello from a Japanese retailer like Yodobashi Camera, where the same unit retails for ¥12,800 (US$85) plus 10% consumption tax, totaling ¥14,080 (US$94). The pre-owned route saves US$4 upfront, but the real value is Reboot Hub's 180-day warranty — a new Tello from a domestic retailer carries a standard 90-day manufacturer warranty with no repair pathway in Japan; if the motor fails on day 120, you are buying a replacement. At Reboot Hub, that same day-120 failure triggers a free repair at the Shenzhen chip-level facility, where MOHRSS Level 3 technicians replace the motor using genuine OEM parts within 3-5 business days. Shipping costs for repair returns to Japan average US$18 DDP. For operators buying three or more Tello units (common for classroom deployments), Reboot Hub applies a 12% volume discount on pre-owned inventory, dropping the per-unit cost to US$59.84. Spare batteries — the Tello uses a proprietary 1S 1100mAh LiPo — cost US$12 each pre-owned (Grade A, 85%+ cycle health verified). Three batteries plus the drone and DDP shipping total US$122, less than the price of a single DJI Mini 4 Pro battery purchased new in Japan.

Reboot Hub から購入する理由 【2】よくあるご質問

Reboot Hub sources every pre-owned drone directly from trade-in programs across 14 Asian markets, with Japan accounting for roughly 22% of all Tello and micro-drone inventory. Each unit undergoes a multi-point inspection at the Shenzhen facility before being graded. This inspection covers IMU calibration drift, motor bearing acoustic analysis (any unit exceeding 42 dB at 30cm distance is rejected), battery internal resistance testing (cells above 80 milliohms are replaced), and full flight telemetry logging across three consecutive charge cycles. Only genuine OEM parts are used for any component replacements — no aftermarket propellers, no third-party batteries, no cloned motor sets. Every drone ships with a 180-day warranty that covers sensor failure, motor degradation, ESC malfunction, and battery capacity dropping below 70% of rated mAh. Reboot Hub handles all DDP (Delivered Duty Paid) shipping from Shenzhen and Hong Kong, meaning the price you see at checkout is the final price — Japan customs clearance, 10% consumption tax, and any applicable handling fees are pre-paid by Reboot Hub. For Japanese customers specifically, the Hong Kong drop-off point (Kowloon Bay service center) processes orders destined for Tokyo, Osaka, and Nagoya with an average customs clearance window of 1.4 days, significantly faster than Shenzhen-origin shipments which clear in 2.8 days on average. If you ever need a repair, the same Shenzhen facility services your drone with a 3-5 business day turnaround, and return DDP shipping back to Japan is capped at US$18 for sub-100g packages.

よくある質問

Q: 2024 年のアップデート後、日本の屋内で 100g 未満のドローンを飛行させるには、ライセンスや登録が必要ですか?

A: No. The 2024 amendment to Japan's Civil Aeronautics Act explicitly removes all MLIT oversight for drones under 100g operated entirely within enclosed structures. You do not need an operator registration number, a Remote ID broadcast module, an aeronautical radio operator license, or any prefecture-level permit. This applies even in publicly accessible indoor spaces like exhibition halls, hotel lobbies, and shopping atriums — the "public indoor space" ambiguity from the pre-2024 framework has been fully resolved. If your drone weighs 99g or less at takeoff and never crosses a building threshold, you face zero regulatory friction anywhere in Japan's 47 prefectures as of January 2024. Private venue policies still apply independently — always obtain venue owner permission.

Q: ドローンの重量が 101g の場合はどうなりますか? 100g の制限には猶予許容範囲はありますか?

A: No tolerance exists. The 100g threshold in Japan's 2024 drone law is absolute and measured as total takeoff mass including battery, propellers, and any attached payload like a camera or sensor. If your drone exceeds 100g by even 1 gram, the indoor exemption evaporates entirely — you must comply with full MLIT regulations including operator registration (¥1,450 annually), Remote ID broadcasting, and in many cases a formal flight plan submitted 10 working days in advance. Reboot Hub's multi-point inspection includes a calibrated digital scale verification (accurate to ±0.5g) for every sub-100g drone sold. We strongly recommend against attaching aftermarket accessories — a 3g LED light or 5g propeller guard can push an 87g Tello EDU past 100g and void the exemption. If you need payload capacity, consider the BetaFPV Cetus Pro at 38g base weight, which leaves 62g of headroom for accessories while staying legal for indoor permit-free flight.

Q: 日本の屋外で許可なくサブ 100g ドローンを飛行させることはできますか?

A: いいえ — 2024 年の屋内免除は屋外には適用されません。 100g未満のドローンは密閉構造物から出ると、重量に関わらず日本の標準ドローン規制に該当します。屋外での飛行には、国土交通省のオペレーター登録（年間 1,450 円、約 9.70 米ドル）、リモート ID 送信機（内蔵または外部モジュール）、および空域制限の遵守が必要です。空港から 300 メートル以内、高度 150 メートル以上、特別な許可なく人口密集地域上空、または国土交通省の事前承認なしに、東京 23 特別区すべてを含む指定飛行禁止区域内での飛行は禁止されています。 100g 未満の重量クラスでは、夕暮れ時の照明の義務化など、100g ～ 200g カテゴリーの追加装備要件は免除されますが、中核となる屋外規制の枠組みは普遍的に適用されます。 Reboot Hub は、特に許可なしで日本で運用するために購入した 100g 未満のドローンを屋内のみで配備することを推奨しています。屋外作業の場合は、組み込みのリモート ID と完全なジオフェンシング準拠をすぐに備えた DJI Mini 4 Pro (249g、Reboot Hub で 589 米ドルの 中古) を検討してください。

Q: Reboot Hub's の多点検査では、100g 未満のドローンが飛行可能であることをどのように確認しますか?

A: The multi-point inspection at Reboot Hub's Shenzhen facility is identical for sub-100g micro-drones and full-size consumer models. For a DJI Tello, the inspection covers: IMU calibration across all six axes (acceptable drift below 0.03 degrees per minute), barometric altimeter accuracy at 1m and 3m hover heights, motor RPM consistency across all four brushless motors (acceptable variance under 3% at full throttle), acoustic bearing analysis (rejection at 42 dB or above measured at 30cm), battery internal resistance testing (cells above 80 milliohms trigger automatic replacement with genuine OEM cells), full flight telemetry logging over three consecutive full-discharge cycles, VPS (Visual Positioning System) sensor cleanliness and IR emitter output verification, 720p camera focus sharpness and color calibration, and frame integrity under UV light to detect hairline cracks invisible to the naked eye. Each inspection report is digitally archived and linked to the drone's serial number — you can request your unit's report before purchase by contacting Reboot Hub support with the inventory SKU. Total inspection time per Tello unit averages 47 minutes, and the rejection rate for trade-in inventory is roughly 18%, meaning nearly one in five units fails and is parted out rather than sold.

Q: 香港から日本への DDP 配送は実際には何をカバーしますか?

A: DDP (Delivered Duty Paid) means Reboot Hub pays all costs from the Hong Kong Kowloon Bay service center to your address in Japan. This includes: export customs clearance in Hong Kong (typically 0.5 days), air freight to Tokyo Narita or Kansai International (priority routing based on proximity to your delivery address), Japan import customs clearance including the 10% consumption tax assessment (averages 1.4 days for HK-origin shipments), any applicable handling fees charged by Japan Customs, and final-leg delivery via Sagawa Express or Yamato Transport with full tracking. For a standard DJI Tello package weighing roughly 400g including packaging, DDP shipping costs US$22 flat to any of Japan's 47 prefectures. The total landed cost — drone plus shipping — has no surprise charges. If Japan Customs assesses additional duties (rare for sub-US$100 declared value electronics from Hong Kong), Reboot Hub absorbs those costs. Average delivery time from order to door is 5-7 business days, with 93% of Japanese orders arriving within the 7-day window in 2024. Okinawa and Hokkaido deliveries may add 1-2 business days due to domestic leg routing.

Q: 屋内で墜落した場合、Reboot Hub は 100g 未満のドローンを修理できますか?

A: Yes — Reboot Hub's Shenzhen chip-level repair facility accepts all sub-100g drones sold through the platform, regardless of warranty status. The repair team consists of MOHRSS Level 3 certified technicians who perform component-level repairs rather than full module swaps. For a DJI Tello with crash damage, common repairs include: motor replacement (US$14 per motor, genuine OEM part, 1-day turnaround), frame arm replacement (US$22 including full shell swap, 2-day turnaround), VPS sensor recalibration (US$18, same-day turnaround if received before 11:00 AM HKT), and battery connector resoldering (US$8, 1-hour turnaround). The average repair takes 3-5 business days from intake to shipping. Return DDP shipping to Japan costs US$18 for sub-100g packages. Crash damage is not covered under the 180-day warranty — that covers manufacturing defects, sensor drift, and battery degradation — but out-of-warranty repairs are priced at cost plus a flat US$10 labor fee. Reboot Hub also offers a Hong Kong drop-off option: if you or a colleague are traveling through HK, you can deliver the drone in person to the Kowloon Bay service center (open weekdays 9:00-18:00 HKT) and pick it up repaired within the same 3-5 day window, saving US$18 on return shipping.

Q: 中古 サブ 100g ドローンの 180 日保証は何をカバーしますか?

A: Reboot Hub's 180-day warranty on all Pristine Pre-Owned (Grade A) and Flawless (Grade A+) drones covers: motor failure or RPM variance exceeding 5% between any two motors, battery capacity dropping below 70% of rated mAh within the warranty period, IMU calibration failure or drift exceeding 0.05 degrees per minute, barometric altimeter error exceeding 0.5m at 3m hover altitude, VPS sensor failure or IR emitter output below 70% of factory spec, ESC (Electronic Speed Controller) malfunction causing uncommanded throttle changes, and frame or shell defects missed during the multi-point inspection. The warranty excludes crash damage, water exposure, battery swelling from over-discharge, and firmware corruption from unauthorized software modification. Claims are processed within 48 hours of receiving the drone at the Shenzhen facility, and repaired units ship back DDP within 3-5 business days. Reboot Hub's warranty claim rate across all sub-100g drones sold to Japanese customers in 2024 was 3.2%, and 97% of claims were resolved with a single repair cycle. For comparison, the standard manufacturer warranty on a new DJI Tello purchased in Japan is 90 days and does not include a repair pathway — defective units are replaced, not repaired, and the replacement unit carries only the balance of the original 90-day period.

Q: 日本の屋内不動産撮影に最適なサブ 100g ドローンはどれですか?

A: For Japanese real estate photography — where tight spaces like 6-tatami rooms and narrow genkan entryways are common — the DJI Tello (80g, US$68 pre-owned at Reboot Hub) is the practical top choice despite its 720p camera limitation. Japan's typical real estate listing resolution requirement is 1080p for online portals like SUUMO and HOME'S, but the Tello's 720p output is accepted for supplementary "aerial room view" shots that show ceiling height and layout flow — these are not primary listing photos. The Tello's VPS (Visual Positioning System) holds position accurately in rooms as small as 2.5m × 2.5m, and its 13-minute flight time covers a standard 3LDK apartment in two batteries. For higher resolution, the BetaFPV Cetus Pro (38g, US$105 pre-owned) supports analog FPV cameras up to 1200TVL resolution with a separate ground recorder, but requires FPV goggle operation — less practical for single-operator real estate workflows. Reboot Hub sells an average of 18 Tello units per month to Japan-based real estate photographers, with 72% opting for the two-battery bundle (US$92 total with DDP shipping to Tokyo) to ensure uninterrupted single-session coverage of properties up to 120m².
