Bicycle Insurance: The Mandatory Coverage
Bicycle insurance is mandatory across most of Japan's major prefectures, and every person who rides a bicycle inside one of them needs qualifying liability cover.12 A single crash can produce damages near 100 million JPY, so the mandate exists to protect victims and keep at-fault riders solvent.34
Procedures, fees, and requirements can change. Confirm current details at the Tokyo Metropolitan Police bicycle insurance page and your prefecture's ordinance page. This article is general information, not legal, tax, or immigration advice; for your specific case, consult a licensed insurance agent.
Overview
Japan has no single national bicycle-insurance law. Each prefecture (and some designated cities) decides by ordinance whether riders must carry bicycle liability cover, so the duty turns on where you ride, not where you live.51
The mandated minimum is cover for another person's life or bodily injury caused by your bicycle use.36 This cover is called 自転車損害賠償保険等 (jitensha songai baishō hoken-tō, "bicycle liability insurance etc.").67
The duty binds adult riders directly, parents for minor children, businesses for work-use riding, and rental operators for loaned bicycles.368 Retailers, schools, and employers of bike commuters confirm joining and provide information but do not join on the rider's behalf.685
Why the mandate exists
Courts handed down bicycle-crash awards on a scale most households cannot absorb, and prefectures answered with compulsory-cover ordinances aimed at victim relief and at-fault financial protection.789
The 2008 Kobe case and the 95-million-yen judgment
In September 2008 in Kita Ward, Kobe, an 11-year-old boy rode downhill at 20 to 30 km/h and struck a 67-year-old woman pedestrian.4 She suffered a skull fracture and never regained consciousness.4
In July 2013 the Kobe District Court ordered the boy's mother to pay about 95 million JPY in total: about 35 million JPY to the victim's side and about 60 million JPY to the insurer that had paid the victim.4 The court found the boy's forward inattention caused the crash and the mother's supervision insufficient.4
The Metropolitan Police records the award as 95.21 million JPY and pairs it with a 92.66 million JPY Tokyo District Court precedent from 2008, showing the Kobe case was not a one-off.3 Nara Prefecture cites the same two precedents as its reason for compulsion.9
What the judgment changed
Before the ordinances, almost everyone agreed cover was sensible and few carried it. A January 2015 Osaka prefecture survey found 95 percent of residents saw the need but only 40 percent were insured.10
Prefectures therefore moved the duty from encouragement to obligation, keeping the twin aims of victim relief and protecting at-fault riders from ruin.789 Kanagawa's ordinance Q&A describes compulsory liability cover as one of the ordinance's two pillars alongside safe-and-proper use.11
Where insurance is mandatory
The mandate map keeps expanding, so treat any list as a snapshot and confirm your prefecture's current ordinance page before acting. Insurer-compiled lists describe the broad shape (as of 2026-01; confirm current status with your prefecture's ordinance page), but only each prefecture's page is authoritative for that prefecture.1
Mandate status by major prefecture
Tokyo mandates joining from 2020-04-01 under its amended bicycle ordinance.36 Saitama mandates joining from 2018-04-01 under its 2017 amendment.12 Nagano mandates joining from 2019-10-01.8 Nara mandates joining from 2020-04-01.9
Kyoto and Osaka mandate joining under their ordinances now in force.713 Kanagawa and Hyogo mandate joining under their safe-and-proper-use ordinances.11 Aichi and Fukuoka appear as obligation areas on insurer-compiled lists (as of 2026-01); confirm each at its prefecture page.1

The table reflects each source's own dating (as of 2026-09-08; confirm current status with your prefecture's ordinance page).1 Older snapshots such as the 2023-04 insurer map are superseded for any prefecture with a newer ordinance-page date (as of 2023-04).2
Who the duty binds
The adult rider joins directly, unless someone else already covers the same use.65 A parent or guardian joins for a minor child, because a minor generally cannot contract alone.367
A business operator joins business-use cover for employees riding in work duties.385 An employee's personal policy may not pay for a work-duty crash, so the business needs its own terms.37
A rental operator joins cover for loaned bicycles, whether the loan is paid or free, including hotel service bikes, and must explain the cover to borrowers.379 Retailers confirm a buyer's joining at sale, while schools and employers confirm students and bike commuters; each provides information where joining is unconfirmed.68129
Visitors are bound too. Kyoto, Nara, and Osaka apply the duty to anyone riding inside the prefecture, including out-of-prefecture commuters, shoppers, tourists, and rental users.7139
What a compliant policy covers
A compliant policy pays damages for another person's death or bodily injury caused by your bicycle use.36 Own injury, your own bicycle, and property damage sit outside the compulsory scope in the ordinances fetched, though many products bundle them anyway.79
Minimum cover the ordinance requires
Kyoto states explicitly that another person's property damage is not part of the mandate.7 Tokyo frames the core Article 27 duty as life-or-body cover, with property cover as an effort duty.6
Nara advises own-injury cover as a personal choice outside the ordinance.9 So a policy qualifies even if it carries no own-injury schedule, as long as its liability limb pays others' bodily injury.39
Typical cover and premium bands
Stand-alone bicycle policies commonly pair personal liability of 100 million JPY to unlimited domestic cover with scheduled own-injury benefits and a settlement negotiation service (as of 2026-09-08; confirm current figures with individual insurers).1412 The 示談代行サービス (jidan daikō sābisu, "settlement negotiation service") means the insurer negotiates with the victim on your behalf.141
Entry individual tiers near 3,000 to 4,000 JPY per year and family tiers near 7,000 to 8,000 JPY per year match the oldest content-plan reference bands (as of 2026-09-08).141
| Product | Annual amount | Liability band | As of | Notes |
|---|---|---|---|---|
| au Bycle Bronze, individual | 3,810 JPY lump sum (340 JPY/mo)14 | 200M JPY | 2026-09-0814 | Road service included |

| Sompo UGOKU, family | 980 JPY/mo2 | Unlimited domestic, 100M overseas | 2026-09-082 | Monthly-join online cover |
The bands above are advertised entry points for late-2026 shopping (as of 2026-09-08).14 Liability of at least 100 million JPY is the sensible floor given the precedents, and unlimited domestic tiers cost little more.392
Where to buy
Start from policies you already hold, because a rider you already pay for often satisfies the mandate with no new purchase. The flow below shows the order that avoids duplicate buying.37
Stand-alone online policies
au Sonpo Bycle sells direct online in individual, family, and spouse-excluded types across Bronze, Silver, and Gold courses, with 1-year and 2-year terms.14 Its liability bands run 200 million JPY on Bronze and 300 million JPY on Silver and Gold, with no deductible and road service on every course (as of 2026-09-08; confirm current figures with au Sonpo).14
Rakuten cycle sells annual-pay online tiers for individuals, couples, and families with point accrual and use (as of 2026-09-08).1 Sompo UGOKU sells monthly-join online family cover with unlimited domestic liability (as of 2026-09-08).2
Nagano's provider list also names ZuttoRide small-amount-and-short-term insurance among personal-use sellers, including no-age-limit mini and standard plans.8 Check age caps before choosing, because commercial bicycle plans commonly cap the named insured at 69 or 74 while some sellers offer senior or no-limit plans.814
Shop-bundled and TS mark cover
The TSマーク (TS māku, "TS mark") is an inspection-and-maintenance seal attached at a registered shop, and its attached cover runs one year from the inspection base date.39 Conditions are limited and colour-dependent, so read the attached terms rather than assuming full cover.3
Because TS cover attaches to the bicycle body, anyone riding that marked bicycle inside its validity period is covered.79 A bike ridden past expiry without another qualifying policy is uninsured even though the sticker is still on the frame.39
A 個人賠償責任保険 (kojin baishō sekinin hoken, "personal liability insurance") rider on cover you already hold usually satisfies the mandate for the whole household.37 Confirm the rider and its amount on your policy papers before paying for a second contract.139
Riders on homeowner, auto, and group cover
Existing auto, fire, or injury policies can satisfy the mandate through a personal-liability rider.3713 PTA and school-window group policies, employer group policies, traffic-safety-association member cover, credit-card attached cover, and mutual-aid riders can also qualify where they carry the right liability limb.38139
One personal-liability contract generally covers the household, including cohabiting relatives plus non-married children living apart, with no per-bicycle pricing.7141 Multiple bicycles therefore need no multiple contracts.71
Overlapping liability covers still pay a given accident from only one contract in effect.1 Compare amounts and terms before deciding whether a new contract adds anything, and take shortlisted options to a licensed insurance agent.1
Enforcement and what non-compliance risks
No fetched ordinance page describes roadside or traffic-stop insurance checks, and Nara states expressly that riders need not carry proof or display anything while riding.9 Compliance is instead confirmed at sale, at school or the workplace, and after a crash.68125
How compliance is actually checked
Retailers confirm a buyer's joining at sale and provide information where joining is unconfirmed.6812 Schools confirm students who commute by bicycle, and employers confirm bike commuters, with information duties where cover is missing.6785
After a crash, liability and cover are verified through the parties' insurers.34 This post-accident verification is the check that actually bites, because an uninsured rider faces the victim's claim alone.39
Fines and liability exposure
Tokyo, Kyoto, Osaka, Nagano, Nara, and (per its Q&A rendering) Kanagawa attach no penalty to non-joining.7810911 Osaka and Kanagawa explain that each rider's mixed portfolio of riders, group policies, and family cover makes a fine unverifiable in practice.1011
This guide describes products only. Which limits, own-injury schedule, deductible, and riders fit your household depends on your riders, bicycles, and mileage, so take shortlisted quotes to a licensed insurance agent before binding cover.1
Good to know
Check existing cover before buying anything new
Many riders already qualify through an auto, fire, or injury policy rider, a PTA group policy, or card-attached cover.3713 Buying a duplicative stand-alone policy wastes the premium while adding no new liability limit, so audit first and buy only the gap.91
A TS mark is inspection-linked cover with a one-year clock, not permanent insurance
TS attached cover lapses one year after the inspection date.39 Diary the expiry and either re-inspect or hold another qualifying policy, because a bike ridden past expiry is uninsured even with the sticker still on the frame.39
One family policy can cover the household, but the member scope needs checking
Personal-liability riders commonly cover cohabiting relatives plus non-married children living apart.7141 Age caps and couple-versus-family plan boundaries still vary by product, so confirm the member scope on your own contract rather than assuming every relative is inside.814
Business-use riding may need business-use terms, not a personal policy
An employee's personal liability policy may not pay for a crash during work duties.37 Businesses need business-use terms such as facility liability cover, and rental operators need loan-use terms covering borrower fault, including free hotel loan bikes.789
Riding uninsured in a mandate prefecture leaves civil exposure even where no officer stops you
No fetched mandate prefecture describes roadside enforcement.379 The duty still binds visiting and rental riders while inside the prefecture, and post-crash liability follows the court precedents, so the absence of checks is not the absence of risk.794
