A short while back I shared some summary trade statistics from Nagasaki I found in Cullen, Louis. (2017). The Nagasaki Trade of the Tokugawa Era: Archives, Statistics, and Management. Japan Review, (31), 69-104.

I decided to go to it's source, the Tsūkō ichiran, compiled by the late Edo bakufu on history of diplomacy and trade with the outside world. The Nagasaki statistics are found in book 4, the Chinese statistics in volume 160 and the Dutch in volume 161.

Historians have already went through this and other sources to compile what stats are available (so those want to do detailed research should hit up a university library), but I thought I'd share this for those interested. The stats transcribed by me can be found here, hopefully without too much transcription errors. The values are rounded to the nearest whole number. Silver is recorded in kanme (3.733.75kg) and gold is recorded in ryō (37.337.5g). At the end of the trade some gold/silver are kept in Nagasaki for the trader to buy food, supplies, pay fees, etc.

Starting from 1648 detailed stats exist until 1672 for the Chinese and 1670 for the Dutch.

For the Chinese:

The records kept the shōgun and court's purchases separately from the reported total, so a combined calculated total is given, value shown in silver.

^N This value is recorded as 126.88 kanme, but doesn't match the recorded exchange rate or the total given. It's assumed to be a typo and 826.88 kanme the correct value.
