Yamanashi Entrance Social Studies common mistakes
Yamanashi Entrance Social Studies · Understand the traps and how to avoid them.
When a map or graph shows a Japanese region's climate, the candidate labels it by the prefecture name alone (e.g., 'because it is Yamanashi, summers are hot') instead of reading the actual plotted values and the axis units, then choosing the climate type from the data.
Candidates memorize prefecture stereotypes from travel or news and treat regional geography as name-recall. They skim the axis labels and the period covered, so a graph of monthly precipitation is confused with temperature, or a basin climate is read as a Pacific-coast climate.
What to do instead
Before answering, write down three things from the figure: what is measured, the units, and the time span. Then state the rule being applied (inland basin = large diurnal and annual range, low winter precipitation; Pacific side = summer rain maximum; Sea of Japan side = winter snow maximum) and check each plotted value against the rule. Practice by covering the place name and identifying the climate type from numbers only.
On industrial-location or population-distribution questions, the candidate gives a single cause ('because there is a port' or 'because it is a big city') and stops, rather than combining the two or three conditions the data actually support.
Textbook summaries list factors as separate bullet points, so students learn them as alternatives. Exam items often require linking a raw-material import pattern with transport and market access, and a one-factor answer feels complete.
What to do instead
Use a fixed checklist for every location question: raw materials and energy, transport (port, rail, expressway interchange), market and labor, and policy or historical path dependence. Explicitly write which checklist items the given data support and which they do not, then build the answer only from the supported ones. If the question gives two data sources, the intended answer almost always joins them.
The candidate dates an event by the era name alone, treating 'Kamakura period' or 'Edo period' as a single point, and so places the establishment of the Kamakura shogunate, the Jokyu disturbance, and the Mongol invasions in the wrong order or the wrong century.
Era names are learned as labels attached to people and artifacts, not as spans with internal sequence. Students also confuse the start of a period with the peak of the institution it is named for.
What to do instead
Build a single horizontal timeline with start and end years for each period and pin the key events to it, then rehearse by covering the years and reciting them. For any event, answer three questions: which period, which century, and what came immediately before and after. Rehearse transitions specifically (Heian to Kamakura, Muromachi to Azuchi-Momoyama, Edo to Meiji), because exam items cluster there.
The candidate answers a source-interpretation item about a medieval document by quoting the passage's wording back, without identifying who wrote it, for whom, and for what purpose, so a lord's regulation is read as a neutral description of society.
Students treat historical sources as information containers rather than as acts by interested parties. They also skip the attribution line and the date at the end of the source, which usually reveal the author's position.
What to do instead
For every source, fill in four slots before answering: author and position, intended audience, purpose, and date. Then ask what the author had to gain. Practice with contrasting pairs, such as a warrior-house code and a peasant petition on the same issue, and state how the two accounts differ and why.
In Azuchi-Momoyama and Edo items, the candidate mixes up the policies of different rulers, attributing the land survey and sword hunt to the wrong figure, or merging the sankin kotai system, the alternate-residence requirement, and the closing of the country into one undifferentiated 'national isolation' policy.
These policies are taught as a bundle of 'unification and control measures', and the names of Nobunaga, Hideyoshi, and Ieyasu are memorized as a list rather than as a sequence of distinct programs with different targets.
What to do instead
Make a three-column table, one column per ruler, and place each measure under its author with its target group and its effect. Separately, list the components of the Tokugawa foreign-relations system (port restrictions, the Dutch and Chinese trade at Nagasaki, controls on Christianity) as distinct measures rather than one word. Test yourself by naming the ruler from the measure, not the reverse.
On modern-history items, the candidate explains a treaty or reform by its outcome alone ('modernization happened') without the causal chain, and confuses the order of Meiji-era events such as the promulgation of the constitution, the opening of the Diet, and the revision of unequal treaties.
Modern history is compressed into a few slogans in review materials, and the sequence of Meiji institutional steps is less familiar than the names of the documents. Students also read later outcomes back into earlier decisions.
What to do instead
Write each major modern event as a chain: external pressure or domestic problem, the policy response, the institution created, and the consequence. For the Meiji period, memorize the order of the constitution, the Imperial Rescript on Education, and treaty revision with their years. When an item offers a 'because it modernized' option, reject it unless the option names the actual mechanism.
On constitutional questions, the candidate answers from personal opinion or from what seems fair ('the Self-Defense Forces are unconstitutional' or 'the Emperor is the head of state') instead of from the text and established interpretation, and misstates which body holds which power.
Civics feels like a discussion subject, so students reason from values. They also blur the roles of the Emperor, the Cabinet, and the Diet, and the distinction between the two houses and between ordinary law and the constitution.
What to do instead
For each item, name the article or principle at issue before choosing: popular sovereignty, fundamental human rights, pacifism, separation of powers, or local autonomy. Learn the institutional facts as a table (who appoints, who approves, who can dissolve, who commands the Self-Defense Forces, who judges constitutionality). When two options both sound fair, choose the one that matches the constitutional text or settled interpretation, and be able to say which.
On economy and public-finance items, the candidate treats the household budget analogy as literal ('the government should just spend less') and confuses the roles of the Bank of Japan, fiscal policy, and the budget, or misreads a deficit or debt figure without checking whether it is a flow or a stock.
The household analogy is intuitive and taught early, and macro terms such as fiscal deficit, primary balance, and government bond issuance are easily conflated. Students also read a percentage without asking 'percentage of what'.
What to do instead
Define each term in one line before answering: fiscal policy is government spending and taxation, monetary policy is the central bank's interest-rate and money-supply action, the primary balance excludes debt service, and a stock is measured at a point in time while a flow is measured over a period. For any figure, write 'X percent of Y' in full. Use the household analogy only to illustrate, never as the basis of a macro answer.
The candidate reads a graph or table by its headline trend only, ignoring the legend, the units, the base year, and whether the vertical axis starts at zero, and so reports a doubling where the change is small or misses a reversal in the later years.
Time pressure pushes students to the first visible slope. Compound graphs with two axes and changing base years defeat a quick glance, and the legend is often the last thing read.
What to do instead
Apply a fixed reading routine: title, legend, both axis labels and units, start and end years, and whether the axis is truncated. Then describe the series in three parts: start value, direction and any turning point, end value. Only after that compare series. Practice on two-axis graphs where the lines cross, and say aloud which axis each line belongs to.
When interpreting a historical source or a map in the skills section, the candidate accepts the first plausible reading and never checks it against what else is on the page, so a map's scale, orientation, or a symbol key is ignored and a distance or direction is misjudged.
Map and source skills are treated as general reading ability rather than as procedures with steps. Students also assume north is up and that the scale is the same across the page, and they do not cross-check a source's claim against a second source.
What to do instead
Use a checklist for every map: orientation and north arrow, scale bar, legend, and the area covered. Measure distances against the scale bar rather than estimating. For sources, compare at least two documents and state where they agree and where they conflict. If the item asks for a conclusion, require that it be supported by a specific line or symbol, and reject conclusions that only 'sound right'.
