Japan Moped Theory study plan

Japan Moped Theory · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Traffic lanes, position on the road and通行方法 (通行区分・走行位置) & Signals, road signs and road markings (信号・標識・標示)

  • Define, in one written sentence each, the legal riding position of a 原付 on a normal road, on a road with a 専用通行帯, and on a road with a 指定通行区分, and name the only situations that let you leave the leftmost lane.

  • Recite the speed limits that apply to a 原付 from memory, including the general cap, the 二段階右折 case, and the special limits on narrow or designated roads, and write each with its source rule.

  • Classify all road signs into 規制標識・指示標識・警戒標識・案内標識 and produce one correct example of each with the action it demands.

  • Identify 30 regulatory signs purely from written descriptions (no pictures) and state for each what a rider must or must not do.

  • Distinguish 中央線, 車線境界線, 外側線 and 路側帯 by function, and say for each whether a moped may cross it and when.

Your checkpoint

A closed-book 40-question set mixing signs and lane rules, scored at 85% or higher, with every wrong answer rewritten as a one-line rule on a single sheet.

Week 2

Traffic lanes, position on the road and通行方法 (通行区分・走行位置) & Signals, road signs and road markings (信号・標識・標示)

  • Draw the correct approach position, signal timing and final path for a left turn, a right turn, and a 二段階右折 at a signalised crossroads, and label where the moped must wait.

  • Explain the 二段階右折 obligation in your own words, list the intersection types where it applies, and state the cases where a moped makes an ordinary right turn instead.

  • Describe the rules for passing, overtaking and being overtaken as a moped, including when staying behind is the only legal option.

  • State the road markings that forbid stopping or parking (禁止駐停車・駐車禁止) and how to tell them apart from a 停車禁止 line at a glance.

  • Explain how to ride through a 路側帯 and a 自転車専用通行帯 without breaking the moped position rules.

Your checkpoint

A hand-drawn map of five different intersections with arrows showing your legal path, waiting point and signal for each, checked line by line against your notes and corrected in a different colour.

Week 3

Intersections, right-of-way and priority rules (交差点・優先関係) & Traffic lanes, position on the road and通行方法 (通行区分・走行位置)

  • Rank who goes first at an uncontrolled intersection using 優先道路, road width, and left-versus-right arrival, and justify each ranking with the rule name.

  • Apply the pedestrian, bicycle and 緊急車両 priority rules at a 横断歩道 and at a corner with no crossing markings, and state what a moped must do when a pedestrian is waiting.

  • Describe the duties at a 踏切 in order: stopping point, window-down listening, checking before crossing, and what to do if the barrier starts to close.

  • Explain 内輪差 and オーバーハング for a turning truck and state where a moped should sit to avoid being caught.

  • Solve ten written right-of-way scenes and name the exact clause that decides each one.

Your checkpoint

A 25-question priority-scenario test scored at 90% or higher, with a one-line rule written next to every question you got wrong.

Week 4

Hazard prediction and defensive riding (危険予測・安全運転) & Intersections, right-of-way and priority rules (交差点・優先関係)

  • Build a list of fifteen hidden dangers (opening car doors, vehicles emerging from alleys, wet manhole covers, gravel at corners, parked-car shadows, crosswind at gaps) and pair each with the specific defensive action you would take.

  • Describe how following distance and speed should change in rain, at night, and behind a large vehicle, and write the numbers you will actually use.

  • Explain 死角 for cars, trucks and buses, and state the three road positions where you are least visible and what to do about each.

  • Read five written scene descriptions and predict the single most likely hazard plus one backup hazard before choosing an action.

  • State the correct braking technique split between front and rear brake on a wet surface and explain why the split changes.

Your checkpoint

A one-page hazard checklist of fifteen scenarios with a matching action for each, used to answer a ten-item hazard quiz at 90% or higher.

Week 5

Moped characteristics, riding posture, passenger and load rules (二輪車の特性・乗車姿勢・積載) & Parking, stopping, lighting and equipment obligations (駐停車・灯火・装備義務)

  • Explain how a moped's small wheels, low mass and short wheelbase change braking distance and stability compared with a bicycle and a 小型自動二輪, and give one riding adjustment for each difference.

  • Describe the correct riding posture - 目線, relaxed elbows, ニーグリップ, wrist position on the throttle - and the posture error that most often causes a fall in the wet.

  • State the passenger rule for a 原付 and the load limits for weight, height, width and length, checking every figure against a current official source before writing it down.

  • List the lighting and equipment obligations: 前照灯 and 尾灯 at night, 警音器 use limits, ヘルメット requirement, and the condition checks (tyres, brakes, chain, lights) to do before every ride.

  • Explain where a moped may and may not be parked, including 駐車禁止 places, 駐停車禁止 places and the 3-hour rule for 駐車.

Your checkpoint

A 20-question quiz on moped characteristics, posture, loading, lighting and parking, scored at 90% or higher, plus a pre-ride check card of eight items.

Week 6

Accidents, emergencies and legal duties at the scene (事故・緊急時の措置と義務) & Driver attitude and responsibilities in traffic society (交通社会の一員としての心得) & Penalties, administrative measures and license administration (罰則・行政処分・免許制度)

  • Write the post-collision sequence in the exact legal order - stop immediately, help the injured, prevent further danger, report to police - and say what changes if someone is hurt versus property only.

  • State the reporting duty for a 物損事故 and explain why leaving the scene even without injury becomes a serious offence.

  • List the five habits of a responsible road user - 思いやり, yielding, patience with elderly and child pedestrians, absolute no drinking and riding, no ながら運転 - and give a concrete example of each on a moped.

  • Explain the 点数制度 in outline: how points accumulate, what triggers 免停 and 取消, and how long a clean record is needed to clear points.

  • Identify which of ten described behaviours carries a penalty, an administrative measure, or both, and name the consequence.

Your checkpoint

A ten-step incident-response card written from memory plus a 15-question penalties and licensing quiz scored at 90% or higher.

Week 7

Traffic lanes, position on the road and通行方法 (通行区分・走行位置) & Intersections, right-of-way and priority rules (交差点・優先関係) & Hazard prediction and defensive riding (危険予測・安全運転) & Signals, road signs and road markings (信号・標識・標示)

  • Complete three timed full-length mock tests and log the cause of every miss as knowledge gap, misread question, or guess.

  • Re-drill your two weakest domains from the error log until each scores 90% or higher twice in a row.

  • Recite all signs and markings on your cheat sheet without looking, and rewrite any that you stumble on.

  • Re-read your one-page summaries of domains 1 through 9 and mark the three facts you are least sure of for a final check.

Your checkpoint

An error log covering every missed question from all three mocks, with 100% of those questions later re-answered correctly.

Week 8

Signals, road signs and road markings (信号・標識・標示) & Traffic lanes, position on the road and通行方法 (通行区分・走行位置) & Intersections, right-of-way and priority rules (交差点・優先関係)

  • Complete five full mock tests under real timing and hold a score of 90% or higher on each one.

  • Confirm the pass mark, the question count and the test-day procedure, including what to bring and how the result is announced.

  • Re-verify every figure in your notes that came from memory alone - speed limits, load limits, distances - against a current official source.

  • Run one 90-minute review of all nine domain summaries and stop studying anything that is not on those sheets.

Your checkpoint

A final mock scored at 95% or higher, with all nine domain summaries condensed into a two-page sheet you can read in 20 minutes.

Week 4: Score 85% or higher on a timed 50-question mock covering domains 2 to 5, and show that every wrong answer has been traced back to a written rule.

Week 6: Score 90% or higher on the combined moped-specific, incident-response and penalty quizzes, and recite the post-collision sequence in order without notes.

Week 8: Score 95% or higher on a final full-length mock under exam timing, with the two-page summary sheet complete and no figure left unchecked.
