Metaplanet company, they have bought 103 Bitcoins today again like in the past and added them to their main holdings. However, I can say that Metaplanet is an aggressive Bitcoin buying company, buying Bitcoins regularly on a weekly basis. They are the most aggressive in Bitcoin buying, which is why many treasury companies have followed Microstrategy company and Metaplnet company and made Bitcoin holdings.
Literally this Japanese company, based on the east coast of Asia, still holds significantly fewer Bitcoins than MicroStrategy, the leader in the Bitcoin market and you mentioned that they buy Bitcoin on a weekly basis. Observe the current development of MetaPlant, where they are buying Bitcoin regularly and it is even true that the treasury strategy they follow is identical. It is true that the president of this Japanese company mentioned that their MetaPlant mid-cap status could be a landmark milestone for the Bitcoin-based company. In this context, it is correct that The inclusion of these companies in stock indices will allow them to funnel passive capital flows into the Bitcoin market. See it has already become Japan's leading Bitcoin treasury and they are included in the FTSE Global Equity Index series.
https://cointelegraph.com/news/metaplanet-added-ftse-japan-all-world-stock-indicesThey have recently pulled 103 BTC around $11.7 million valued and now have 18991 BTC worth of $1.95 billion. So with this they have become biggest Bitcoin treasury company in Japan & 7th largest globally i think

They have also been upgraded from the small cap segment to the mid cap, so this qualifies them to appear in the FTSE Japan & FTSE All-World indices, making them accessible to passive institutional inflow

In fact, those treasury companies have yet to set out clear audit standards, right? Sherlock-level questions were put by
Financial Times about the ability to check these holdings as Metaplanet does not present wallet addresses, but relies on third party attestation. whatever it seems they are piling up BTC & are also entering major indexes

This is the big question of the period "Who Holds bitcoin Reserve? Many countries, Companies, Institutions, and individuals are coming to the investment of bitcoin. UAE has come to join the race to invest in bitcoin and it has invested in bitcoin with $700 millions, yet US still dominate with 198,000 BTC.
That is there is a serious competition on the holding of bitcoin in the international investment system of bitcoin.
