Japan Moped Theory study plan
Japan Moped Theory · Give each week a clear focus.
8 weeks · About 6 hours per week
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.
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.
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.
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.
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.
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.
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.
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.
