These are the facts (my apologies for English only).
Kumiko Miyake 久宙美(くゆみ) first came to a 'Vegan Society of Japan' event in Kyoto in 2009. She attended a number of training sessions in which we discussed the work of Vegan Society of Japan, the form and structure and the projects we were working on.
We spent many hours talking to her and encouraged her to start a local Vegan Meetup group in Kansai. She put on a number of social events.
Unfortunately, Kumiko not able to do any of the difficult work we needed, e.g. translating the Vegan Society (UK) articles and constitution into Japanese, or working on the Vegan Sugar Project.
She was friendly but her help was limited. Many times she would telephone us to ask what she could do, and we gave her ideas and encouragement.
In June 2010, a Vegan Society introduction event was held in Osaka. Individuals came from Shikoku, Tokyo and Kansai.
After the end of the evening, Kumiko started to attack us in an angry and irrationally way. We have heard she has attacked others too.
She was trying to split the group, and capture interested individuals.
Why?
In fact, we discovered that two weeks BEFORE the Vegan Society event, Kumiko had ALREADY registered two nearly identical domain names to ours, ' vegan-japan.info' and 'vegansocietyjapan.com'. They were copies.
Although she did not tell anyone, it was a secret to her, Kumiko had planned to start up her own Vegan Society, with no connection to the original society.
Kumiko took and copied all the ideas we had shared with, changing only her logo. Many good opportunities were lost or damaged.
