In Matsushiro, located within central Japan, more than 700,000 earthquakes occurred over a 2 year period (1965-1967). These earthquakes have been related to fluid injection, strike-slip fault movement and the Nigata earthquake as a precursor quake.
Our goal is to perform a rescaled range analysis of the temporal serie to be compared with other swarms all around the world, and with different genesis (volcanic, induced, tectonic, intraplate, etc.)
Thank you in advance
Hi Raul,
Have you tried the Matsushiro Seismological Observatory (http://www.data.jma.go.jp/svd/eqev/data/matsushiro/en/index.html)?
Cheers,

Hi Matt,
Thank you for the link, although I tried but the link url was disabled

Hi raul,
I googled quickly in Japanese but could not get useful info.
I am not sure but you can get it from NIED or HI-net HP, which usually seismologist get seismogram.
Hope

Hi Yusuke!!
Thank you for your post. I tried NIED agency as a register user and HI-net, but only earthquakes from 2002 are available.
Cheers,
Raúl
Hi, Raul,
Contact Japan Meteorological Agency, or JMA, and request the data you want to obtain. I looked at and analyzed the earthquake swarm data decades ago. I am almost certain you will get what you want.

Dear Professor Chun,
Thank you very much for your message. I will contact with the JMA for querying the data.
Best regards from Spain

Hi Qi Yao,
Yes, I am still interested although as you said, I am interested for earthquakes greater than M2.2 (to be honest, I am not sure about the Magnitude of completeness for this swarm). Anyway, no problem for emailing
Cheers
