    Monthly series for an item (value, quantity, unit price, YoY, MoM, preliminary/revised). With flow=both, exports, imports and the balance side by side. Chapters and sections start in 1988; 9-, 6- and 4-digit codes start in 2022. Use freq=year for long-term trends, or set from for older months (without from, months start in January 2022). Some import chapters and sections for April 2018–December 2019 return no value but gap="source" with an explanation, because the source e-Stat table lacks data. This does not mean there was no trade. / 品目の月ごとの推移(金額・数量・単価・前年比・前月比・速報/確報)。flow=both なら輸出・輸入・差し引きを並べます。類・部は1988年から、9桁・6桁・4桁は2022年から。長期の推移は freq=year、月ごとの過去分は from を付けます(from を省くと2022年1月から)。輸入の類・部の 2018年4月〜2019年12月の一部は、元データ(e-Stat の統計表)に欠けがあるため値を返さず gap="source" と説明文を返します。取引が無かったという意味ではありません。
