Value Village ／ Everyday know-how

The upright bicycle with a basket, a bell and often a child seat — the "mamachari" — is how Japan runs its errands. It is unglamorous, ubiquitous and governed by a set of rules that changed significantly in 2023 and 2026.
| Item | Detail |
|---|---|
| The mamachari | Upright frame, 26–27-inch wheels, basket, mudguards, chain guard, hub dynamo light, rear rack; 1–3 gears; ¥15,000–40,000; electric-assist (e-mamachari) ¥100,000–150,000, dominant for parents |
| Registration | Anti-theft registration (防犯登録) is mandatory — about ¥600 at purchase; the sticker is checked by police |
| Helmets | Duty of effort for all ages since 1 April 2023; not yet a fine; adoption around 15–20% nationally in 2024 |
| Lights | Required after dark; fines apply |
| Where to ride | Roadway, left side, in principle; pavements only where signed, for children under 13, over 70, or where the road is dangerous; ride slowly and give way to pedestrians |
| Prohibited | Phone use while riding, riding under the influence, umbrella in hand, two abreast, riding without lights, carrying an adult passenger; children: up to two under 6 in approved seats with helmets |
| Penalties | Since 1 November 2024: phone use up to ¥100,000 fine / 6 months; drunk riding up to ¥500,000 / 3 years (criminal). From April 2026: "blue ticket" administrative fines (¥5,000–12,000) for common violations by riders 16+ |
| Parking | Station and shopping-area bicycle parks (free or ¥100–200/day); bikes left outside are removed by the municipality, retrieval fee ¥2,000–5,000 |
| Insurance | Liability insurance mandatory in Tokyo and most prefectures since 2020; often bundled with household policies |
[Verify] Penalty details with the National Police Agency's 2024 Road Traffic Act amendments and the 2026 blue-ticket system; insurance requirements with each prefecture.
Registration, lights, left-side road rule, helmet duty, criminal penalties for phones and alcohol, fines from 2026. Police stop cyclists routinely to check registration.
The roadway is the rule; pavements are permitted only where signed, for children and the elderly, or where the road is unsafe, and at walking pace giving way to pedestrians. Enforcement has tightened.
Municipalities remove bikes from no-parking zones daily; getting one back costs ¥2,000–5,000 and a trip to the depot. Use the bicycle park (often underground or automated).
Illegal (one-handed riding). Residents use a rain poncho or a fixed umbrella holder, which is legal in most prefectures if it does not obstruct.
Duty of effort for everyone since 2023, and the fatality data are the reason. Uptake is rising fastest among parents and commuters; a fine may follow.
