Cannot access site from japan?

I have posted content to my web site www.meetinginamerica.com, but people cannot access it from Japan. I have purchased the domain from godaddy.com and have hosting through ipowerweb.com. Has anyone else experienced this, and if so, is there a workaround, such as getting different nameservers, or asking the hosting company to use different IP addresses? How do I tell if IP addresses are banned/blocked?

I would contact whoever you are paying money to but a temporary workaround is for the Japanese to use a US proxy such as from: http://proxy.org/
