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). / 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）。
