How can I invest in Vanguard Index tracker funds (not ETFs) from Japan?

[tehillah]

I'm an Brit living in Japan who would like to invest in Vanguard Index tracker funds. I spoke to Interactive Brokers Japan and thru them I can invest Index Tracker ETFs, but I'm not interested in ETF's because I think they're just a way for brokers to take people away from plain index tracker funds which have minimal fees, and to turn them into essentially stocks again so they can make more money. ETF's are not good long term and contain hidden costs in the price. Living in Japan I can't open an Interactive Brokers UK account which would give me access to plain index tracker funds. Does anyone know of an online trading platform which I could use from Japan and allow me to invest in non ETF, index tracker funds? Thank you very much.
